Answer:
i would like to say true
Explanation:
Atoms cannot be brand new in any product or organism.
Answer: False
Explanation:
Atoms are structures that are basic for all molecules. According to the law of conservation of mass it is said that atoms can neither be created nor be destroyed but they are transferred from one form to another, thereby the atoms of any elements that form a new product would have already been derived from the same element in the reactant, they would just be rearranged or will attain a different structural arrangement in order to form a new product.

Before starting kindergarten, Tina had to receive shots to protect her from an infectious disease called measles. Does Tina now have active or passive immunity against measles?
Answer:
i think it's passive
Explanation:
Passive immunity is provided when a person is given antibodies to a disease rather than producing them through his or her own immune system.
Final answer:
Tina has active immunity against measles, which she acquired through vaccination. This has prepared her immune system to fight off future exposure to the measles virus, ensuring she is protected against the disease.
Explanation:
Tina has received active immunity against measles. Active immunity occurs when the immune system is exposed to a pathogen or parts of a pathogen and develops its own antibodies in response. Vaccinations, like the MMR vaccine which stands for measles, mumps, and rubella, introduce a weakened or dead form of the pathogen into the body without causing illness.
This stimulates the body's adaptive immune response to produce antibodies, providing long-lasting protection against these diseases. Tina's body will now have the memory to recognize and effectively fight off the measles virus should she be exposed to it in the future, thanks to the process initiated by the vaccine.
Read each example and decide what the resulting effect on the gene pool of that population would be.
A zebra migrates to join a different herd of zebras.
Competition for sunlight leads to taller trees.
The DNA of a snake changes to make its venom stronger.
A grassfire randomly sweeps through a population of buffalo and kills most of the animals.
A zebra migrates to join a different herd of zebras.
This would lead to biodiversity in the new zebra herd.
Competition for sunlight leads to taller trees.
Taller trees would prosper, and shorter trees would die out. Trees would continuously evolve to be larger.
The DNA of a snake changes to make its venom stronger.
This mutation created biodiversity and favoritism in natural selection. The trait will more likely be passed on.
A grassfire randomly sweeps through a population of buffalo and kills most of the animals.
Only the strongest Buffalo survived, decreasing competition strengthening the gene pool.
Answer:
Genetic variation as it is an important factor causes evolution by increasing or decreasing the frequency of alleles in a particular population through the process of natural selection.
On the basis of knowledge about genetic variation, we can conclude that-
1st example - Increase in gene pool of zebra.
2nd example - Decrease in gene pool of trees.
3rd example - Increase the gene pool of snakes.
4th example - Decrease of gene pool of buffalo.
Question 7 options:
If the DNA sequence reads TAT, what is the mRNA codon?
Answer:
AUA
Explanation:
Thiamine pairs with Adenine. However, in mRNA, the Thiamine base does not exist. It is replaced by Uracil. Therefore, instead of the A in the DNA strand pairing with a T, it pairs with a U on the mRNA.
The DNA sequence that reads TAT gives rise to an mRNA codon that corresponds to the amino acid tyrosine
Explanation:
According to the central dogma of life the DNA gets transcribed to RNA which gets translated to the protein, the protein is the ultimate macromolecules that helps in the metabolic activities of the human, an important aspect of this process is that not all DNA is converted into RNA similarly not all RNA is converted to protein, only the mRNA is converted to the protein based on a degenerative codon mechanism.
Which of the following is NOT a function of the stem of a plant?
a
storage of nutrients
b
absorption of water from soil
c
structural support for the plant
d
transport of water from roots to leaves
Answer:
Absorption of water from soil
Explanation:
That's what the roots do :)
Absorption of water from soil is not a function of the stem of a plant.
What is Stem?In botany, the stem is the axis of the plant that produces leaves, buds, and shoots that terminate in roots. The stem transports nutrients, water, and minerals to other plant parts. It can also store nutrients, and green stems can even manufacture their own food.
The principal vertical stalk in most plants is the stem, though it can vary in appearance and resemblance to other plant parts (e.g., underground stems may look like roots).
The stem's main jobs are to support the leaves, carry nutrients and water to the leaves so that photosynthesis can turn them into useful substances, and then carry those substances from the leaves to other sections of the plant, including the roots.
Therefore, Absorption of water from soil is not a function of the stem of a plant.

how can molecular biology be used to trace the process of evolution?
Answer:
Explanation: At the molecular level, the universal genetic code and homologous molecules provide evidence of common descent.
Final answer:
Molecular biology can be used to trace the process of evolution by analyzing the molecules and DNA found in living things. Molecular clocks calculate differences in DNA sequences to determine relatedness and divergence time. Molecular biology provides features that reflect evolutionary lineage and ancestral relationships.
Explanation:
Molecular biology can be used to trace the process of evolution by analyzing the molecules and DNA found in living things. Scientists use molecular clocks, which calculate the number of differences in DNA sequences or amino acid sequences between species, to determine how closely related they are and when they diverged from a common ancestor. The fewer differences, the more recently two species split and began to evolve separately. Molecular biology also provides characteristics that are unlikely to be shaped by natural selection, allowing researchers to trace ancestry based on shared features.

what is the effect on the blood flow in the blood vessel artery when a person is running ?
The arteries (red) carry oxygen and nutrients away from your heart, to your body's tissues. The veins (blue) take oxygen-poor blood back to the heart.
Increases in peripheral resistance, blood volume, and cardiac output result in higher blood pressure. Conversely decreases in any of these factors lead to lower blood pressure. Three main sources of peripheral resistance: Blood vessel diameter, blood viscosity, and total vessel length.
Cardiovascular Response to Exercise. As muscles begin exercising, the arterioles serving the muscle dilate to provide more blood flow. However, arterial pressure does not decrease because other parts of the cardiovascular system are adjusted to support the increased blood flow to the muscles.
Hope this helps :)
Final answer:
While running, a person's body increases blood flow to support increased oxygen and nutrient demands. The average radii of blood vessels increase, and the viscosity of the blood decreases to facilitate this. These changes enhance the delivery of oxygenated blood to active muscles.
Explanation:
When a person is running, the body's demand for oxygen and nutrients increases sharply. This demand is met by the cardiovascular system, which adjusts by increasing blood flow. During vigorous exercise such as running, the heart rate and blood pressure rise to pump more blood through the body. Additionally, there are changes at the microvascular level, where the arterioles and capillaries dilate—a process known as vasodilation. This increases the radius of the blood vessels, thereby reducing the resistance to blood flow. According to the principles of fluid dynamics, blood flow (Q) is directly proportional to the fourth power of the vessel radius (r) as per the formula Q = πr^4ΔP/8ηl, where ΔP is the pressure difference, η is the viscosity, and l is the length of the vessel. Therefore, during running, the average radii of blood vessels increases to accommodate the increased blood flow, which can be up to 10 times the resting rate, and the blood's viscosity decreases, allowing the blood to flow more easily.
Furthermore, due to the increased metabolic activity, the body also releases certain chemicals like nitric oxide which contribute to vasodilation. The overall effect is that more oxygenated blood reaches the muscles that are working hard during exercise. As a result, blood flow in the artery and other vessels increases, but it's important to note that this hyperemia, or increased blood flow, is tightly regulated and is a normal physiological response to exercise.
In contrast, the presence of plaques in the arteries can greatly reduce blood flow. A decrease in the vessel's radius due to plaque buildup can lead to a significant decrease in blood flow, which the body may attempt to compensate for by increasing blood pressure, but this can be hazardous to cardiovascular health. It's worth noting that during rest, the arterioles and capillaries also allow for an efficient exchange of substances due to their slower blood flow rate.

Algae can reproduce by _____. fission sexual reproduction fragmentation all of the above
Answer:
fragmentation
Explanation:
Algae can reproduce by fragmentation. Most algae that are small reproduce asexually using fragmentation or by cell division. Larger algae on the other hand reproduce by use of spores. Fragmentation is a mode of asexual reproduction in which the parent divides into two or more fragments which later develops into a new organism.A good example of an algae that uses fragmentation is green algae also called Spirogyra. The parent divides into distinct pieces which can then produce an offspring.The correct answer is All of the above
Explanation:
Algae include multiple organisms that are mainly classified as eukaryotic and rely on photosynthesis like plants, although they are quite different from plants. In terms of reproduction, algae can reproduce in many ways depending on the sécies, this includes asexual reproduction that occurs through fission in which cells divide into two or more cells to reproduce; fragmentation in which the algae breaks into different fragments and each of these is able to form a new complete individual and also, algae can reproduce through sexual reproduction which means there are female and male gametes involved. According to this, it can be concluded algae can reproduce by all of the above (fission, sexual reproduction, and fragmentation).

A student observes a star from two positions of Earth in its orbit, in summer and winter, and measures the change in the position of the star. Which of these can be best calculated by this method?
the shift in light traveling from star to Earth in winter
the shift in light traveling from star to Earth in summer
the distance of the star from Sun using parallax method
the distance of the star from Earth using parallax method
the answer for this question is the distance of the star from sun using parallax method
Answer:
The correct answer will be option the distance of the star from Sun using parallax method.
Explanation:
Parallax method or trigonometric parallax is a method of measuring the distance of nearby stars in space on the basis of displacement of stars against the background.
Since a student observes the position of the star in summer and then after 6 months in winter, star changes its position or displaces which can be measured by the student along with measuring parallax angle and drawing a baseline from the Sun as Earth revolves in orbit around the Sun. So by using the parallax method and the formula he can easily determine the distance from the Sun.
Thus, the distance of the star from Sun using the parallax method is the correct answer.
Which of the following equations represents the right chemical process that occurs in photosynthesis?
A. Six molecules of carbon dioxide plus sugar plus light energy converts six molecules of carbon and six molecules of oxygen.
B. Six molecules of water plus six molecules of hydrogen plus six molecules of oxygen converts light energy plus sugar.
C. Six molecules of carbon dioxide plus six molecules of water plus light energy converts six molecules of oxygen plus sugar.
D. Six molecules of oxygen plus six molecules of water plus light energy converts six molecules of carbon dioxide plus sugar.
Answer:
C. Six molecules of carbon dioxide plus six molecules of water plus light energy converts to six molecules of oxygen plus sugar.
Explanation:
Photosynthesis is the process in which green plants manufacture their food in the presence of carbondioxide and water using light energy. The product of photosynthesis is usually sugar and oxygen gas.
The equation is given below:
6CO₂ + 6H₂O + light energy ⇒C₆H₁₂O₆ + 6O₂
sugar
This is the equation of photosynthesis. Photosynthesis is used by green plants which are autotrophs to manufacture their food.
"The correct option is C. Six molecules of carbon dioxide plus six molecules of water plus light energy converts to six molecules of oxygen plus sugar.
Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose (sugar). The overall chemical equation for photosynthesis can be written as follows:
[tex]\[ 6CO_2 + 6H_2O + \text{light energy} \rightarrow C_6H_{12}O_6 + 6O_2 \][/tex]
This equation shows that six molecules of carbon dioxide (COa‚) react with six molecules of water (HaO) in the presence of light energy to produce one molecule of glucose (C₆Hâ‚â‚‚O₆) and six molecules of oxygen (Oâ‚‚).
Let's analyze the options given:
A. This option incorrectly suggests that sugar is a reactant rather than a product.
B. This option incorrectly includes hydrogen (Hâ‚‚) as a reactant and omits carbon dioxide (COâ‚‚).
D. This option incorrectly suggests that oxygen (Oâ‚‚) is a reactant rather than a product and omits carbon dioxide (COâ‚‚).
Option C correctly identifies the reactants as carbon dioxide (COâ‚‚) and water (Hâ‚‚O), and the products as oxygen (Oâ‚‚) and glucose (sugar), with light energy being the driving force for the reaction."

The term 'parents' refers to individuals who are responsible for the care and upbringing of their children. This term can also extend to grandparents or extended family members in cases where they take up the role of the primary caregiver. In genetics, 'parents' also refer to organisms contributing genetic material to offspring.
Explanation:The term 'parents' is commonly used in a social or familial context to refer to individuals who have offspring either biologically, through adoption, or through other familial relationships. They are responsible for the upbringing and care of their children.
'Parents' in a wider context can also include 'parents of parents', often referred to as grandparents who, in many cultures, play a crucial role in a child's upbringing. In certain circumstances, these grandparents may take on the role of primary caregivers, effectively becoming parents themselves.
Beyond direct parenting, there are several forms of family structures, including single-parent families, blended families (where there are step-parents and/or step-siblings), and extended families, where others like aunts, uncles, cousins also play significant roles in a child's upbringing.
Additionally, in genetic terms, the term 'parents' is used to describe individual organisms that contribute genetic material to create offspring. This biological concept of parents exists parallel to, and distinct from, social and legal aspects of parenthood.

When does the cell pinch off and divide into two daughter cells in mitosis?
A. Telophase
B. Interphase
C. Cytokinesis
D. Anaphase
Answer:
C. Cytokinesis
Explanation:
During the cell cycle, the division of cytoplasm (cytokinesis) is followed by the division of the nucleus (karyokinesis). Cytokinesis is occurred differently in plant cells and in animal cells during cell division. In animal cells, the plasma membrane of the parent cell pinches inward along the cell’s equator until two daughter cells are formed whereas, in plant cells, cytokinesis takes place by a cell plate formation
In mitosis during cytokinesis phase the cell pinches off and divide into two daughter cells .The correct option is C.
In cell biology, mitosis is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei. Cell division by mitosis gives rise to genetically identical cells in which the total number of chromosomes is maintained. Therefore, mitosis is also known as equational division.
In general, mitosis is preceded by S phase of interphase and is often followed by telophase and cytokinesis; which divides the cytoplasm, organelles and cell membrane of one cell into two new cells containing roughly equal shares of these cellular components. The different stages of mitosis altogether define the mitotic (M) phase of an animal cell cycle. In cytokinesis,the cell pinches off and divide into two daughter cells in mitosis.
Thus, the cell pinch off and divide into two daughter cells in mitosis during cytokinesis. The correct option is C.

The students in Mrs. Smith's class tested various paper towel brands for strength. The students collected data after they each performed the same experiment with the different brands. When comparing results; Bounty came out on top. How do we know the test results were valid?
Answer:
The Answer Is C
Explanation:
Final answer:
The validity of the paper towel experiment is supported by consistent setup, methodological uniformity, reproducibility, and sufficient sample size. Assuming these criteria were met, the findings suggesting Bounty as the strongest brand is likely valid. Moreover, consistency and controlled conditions are critical for reliable scientific results in various experiments.
Explanation:
To ascertain the validity of the test results from Mrs. Smith's class experiment, one must consider certain criteria. Several factors contribute to the validity of the paper towel brand strength experiment:
Consistency in the experiment setup for testing each brand of paper towel to minimize variables.Utilizing the same method and conditions for each trial to ensure that the measurement of strength is comparable across brands.The reproducibility of the results when the experiment is repeated under the same conditions, meaning other classes or students could perform the same experiment and get similar results.The collection of a large enough sample size to analyze the data and reduce the effect of anomalies.Considering the information provided, we can assume the experiment was valid if these factors were followed. If all students reported Bounty as the strongest, and if the experiment was conducted under standardized and replicable conditions, this indicates a high likelihood of validity in the findings.
Furthermore, the experiments with the populations of beads, DNA amounts from fruits, airflow tests, and the force standards involving rubber bands also emphasize the importance of controlled conditions, replication, and accurate measurement to establish validity in experimental results. The phrase, 'Which experiment had the correct results? They both did. The job of the statistician is to see through the variability and draw appropriate conclusions'', suggests that multiple consistent outcomes lead to valid conclusions in scientific inquiry.
