Assume that tall (represented by T) is dominant over short stature (represented by y) in corn. If
a heterozygous tall plant is crossed with a short plant, show, using ratios the genotypes and
phenotypes you would expect the seeds from this cross to produce
a. Genotypes _____________________________________________
b. Phenotypes ____________________________________________
Answer:
a. 1 : 1
b. 1 : 1
Explanation:
In this case, a heterozygous tall plant (Ty) is crossed with a homozygous short plant (yy) - which we can deduce as the recessive alleles only exhibit themselves in the absence of the dominant alleles.
The resulting offspring would have the genotypes (refer to attached image):
Ty (Tall)
Ty (Tall)
yy (short)
yy (short)
The genotypic ratio would be - 1:1 (Ty & yy are the genotypes present)
and the phenotypic ratio would be - 1:1 (tall and short are the phenotypes present)
Hope this helpsWhat distribution pattern describes wolves that live in packs? independent uniform random clumped
Answer:
definitely uniform
cos they're not independent cos only rabid wolves r independent unless a wolf got left behind or something, not clumped, wolves hunt in an organized pattern and most definitely not random
The wolf pack structure is a type of population distribution called clumped distribution.
Clumped dispersion. In a clumped dispersion, individuals are clustered in groups.
A clumped dispersion may be seen in plants that drop their seeds straight to the ground—such as oak trees—or animals that live in groups—schools of fish or herds of elephants.
What is the difference between clumped uniform and random dispersion?Clumped dispersion is when individuals in a population are clustered together, creating some patches with many individuals and some patches with no individuals. In uniform dispersion, individuals are spaced evenly throughout an area. And in random dispersion, individuals are arranged without any apparent pattern

What's responsible for preventing the gas giants from collapsing into a star?
Gas giants do not have enough mass that holds much gravitation force to ensure collapsing into a star. The gravitation pull is not strong enough to cause the fusion of hydrogen atoms. These gas giants, such as Jupiter, therefore, do not become stars.
Answer:
They spin very quickly on their axes.
Explanation:
The gas giants spin very quickly, creating a strong centrifugal force. This strong centrifugal force prevents them from collapsing under gravity.

The characteristics of two layers of Earth’s crust are listed.
Layer A: Hard, rigid outermost layer of Earth
Layer B: "Plastic" layer containing the mesosphere
Which statement is true?
Layer A is the crust and Layer B is the mantle.
Layer A is the mantle and Layer B is the crust.
Layer A is the outer core and Layer B is the inner core.
Layer A is the inner core and Layer B is the outer core.
Answer:
Layer A is the crust and Layer B is the mantle.
Answer:
Layer A is the crust and Layer B is the mantle.
Explanation:
The crust is the hardest and hardest layer on earth. It is an external and solid layer, consisting mainly of rocks, soils and a variety of minerals. It can be classified as terrestrial crust, or oceanic crust (when it is below the ocean).
The Mantle, in turn, is located just below the crust and has a more plastic consistency, being a less rigid layer than the crust. The mantle extends to almost half the earth's radius and its apparent "plasticity" is the result of magma.
Mitochondria are organelles that
A. are necessary for the process of diffusion to take place
B. are found in the nucleus of some cells
C. initiate cell division in living cells
D. contain respiratory enzymes
Answer:
D-contain respiratory enzymes
Explanation:
the inner membrane of the mitochondrion folds into cristae that increases the surface area of attachment of respiratory enzymes.
Mitochondria contain respiratory enzymes that are used in the production of ATP, the energy source of the cell, via the process of cellular respiration. They are like power plants for cells but do not initiate cell division, are not found in the nucleus, and are not necessary for diffusion. Hence the correct option is D.
Mitochondria are organelles known as the "power plants" of the cell because of their role in cellular respiration. Out of the options provided, the correct answer to the question of what mitochondria are necessary for is contain respiratory enzymes Mitochondria contain enzymes that are crucial for the process of converting energy from organic compounds into ATP (adenosine triphosphate), which is the energy source for the cell. This process, known as cellular respiration, involves a series of reactions where nutrients are broken down and their energy is captured in the form of ATP. The double-membraned structure of the mitochondria houses the respiratory enzymes and other molecules needed for ATP production. Mitochondria are not found in the nucleus of cells, they do not initiate cell division, and they are not necessary for the process of diffusion to occur.

which layer or Earth has partially melted material that moves the tectonic plates??
A - Crust
B - Inner Core
C - Mantle
D - Outer Core
Answer:
Mantle
Explanation:
The correct answer is C. Mantle
Explanation:
The Earth's mantle is one of the layers that compose Earth; this differs from other layers because it is partially melted and it represents most of the volume of Earth. Besides this, its composition and location below the outer core make this layer responsible for changes and phenomena in the surface such as volcanoes, new mountains, and Earthquakes, this is because the tectonic plates are over the mantle and the mantle is composed of soft and flexible materials that move and change. According to this, the mantle is the layer with partially melted material that moves the tectonic plates.

The Smith family is afflicted with a genetic disorder known as Pinocchio nose syndrome, which causes affected adults to grow noses in excess of five inches long. 100 members of the Smith family show up for a family reunion. Of the fifty-three women, thirty-seven have unusually large noses. Of the forty-seven men, thirty-six have an enormous nose. Based on these figures, Pinocchio nose syndrome is probably
A) dominant and sex-linked.
B) recessive and sex-linked.
C) dominant, but not sex-linked.
D) recessive, but not sex-linked.
Answer:
C- Dominant, but not sex-linked
Explanation:
The disorder is not sex-linked because almost equal numbers of people have Pinocchio nose syndrome. If the disorder was sex linked you would have way more men than women having the disorder.
You can tell that the genetic disorder is dominant because there is a 3:1 ratio for those who have the disorder.
36 out of 47 men ≈0.765
37 out of 53 women≈0.69
These numbers approximate a 3:1 ratio (even if it's not exact), meaning that the disorder is most likely dominant
the answer is actually D. not sex-linked but unable to tell if it is dominant or recessive
Elizabeth is getting ready to run a marathon. She's hoping that the ATP in her body is good for long-term energy storage for the race. Why is her thinking incorrect?
Answer:
Her Thinking is wrong because ATP is not a long term Energy Storage.
Explanation:
We need energy to perform every single task of everyday life. This energy is obtained from the food we eat. There are three main sources of energy in our food.
1. Carbohydrates
2. Lipids
3. Proteins
Carbohydrates are hydrolyzed into glucose upon breakdown and this glucose is used as energy by most of the cells. While Lipids are more complex molecules and usually used to store energy to be used later. Proteins help in muscle building and provide essential amino acid to the body.
There are two ways to store energy, Long term storage and short term storage. The ATP is obtained by breaking down the large molecules and considered as short term energy as it last for only few seconds. While the long term energy is obtained from lipids hydrolysis.
Answer:
ATP is an unstable molecule
Explanation:
Recall that ATP and ADP are too unstable to serve as long-term energy storage units. In contrast, glucose has a stable molecular structure, so it stores energy more efficiently than ATP.

How can you quantify total biomass in a region?
Total biomass in a region is quantified by measuring the blank mass of all the plants and blank in a population, habitat, or region.
Answer:
Quantifying biomass will depend on the quantity of the biomass and what is being measured. Biomass is the mass of living biological organisms in a given area, species or community at a specified time, which include plants, microorganism or animals.
Answer:
The correct answer would be - 1) Dry and 2) animals.
Explanation:
The biomass is the total or collective mass of the dry matter available in the particular ecosystem at any particular time. The representation of biomass is a pyramid known as the pyramid of biomass.
Biomass includes the animals and plants and other organisms present in that ecosystem.
Biomass is the total mass of all living material within a certain area. This includes all plants, animals and other organisms found there. The area is defined by a scientist so that it can be a specific habitat or region.
Thus, the correct answer is - 1) Dry and 2) animals.

how are mitosis and meiosis similar?
Answer:
Explanation: both involve cell division although meiosis breaks it down farther. they have the same process names as well.
Answer:
Cell division is taken by two different means: meiosis and mitosis. Both types of cell divisions have similarities even though they have a different purpose. The mitotic cell division generates 2 daughter cells with the same number of chromosomes while meiosis produces 4 daughter cells with half number of the chromosome to their parent cells.
Except for this, meiotic and mitotic cell divisions are similar in the mechanism. Both cycles go through multiple stages. In these multiple stages both meiotic and mitotic cell division experience the same events as DNA replication and condensation, spindle formation, segregation of chromosomes and nuclear formation .
Thus, both cell cycles have several similarities.
Which should be true about a research topic? A. It should have unlimited scope. B. It should be of interest to you. C. It should have been researched by at least two others. D. It should have a large number of keywords.
A research topic should be of interest to you (option B). It should engage your passion, have a manageable scope, be nuanced and debatable, and allow for various perspectives.
Explanation:When choosing a research topic, it should be of interest to you - option B is correct. A good research topic is one that engages your curiosity and passion, which can make the researching and writing process more enjoyable and fruitful. A topic with unlimited scope would be too broad to handle in a single paper and creating a research question with too many specific keywords could limit the exploration of the topic. Moreover, while it can be beneficial if the topic has been previously researched, it is not a requirement that it must be researched by at least two others; what matters is that you can find sufficient material and evidence to support your research. Lastly, the topic should be nuanced and debatable, allowing for various perspectives and insights rather than a simple yes-or-no question.
Which hypothesis is best supported by this graph?
A graph is supported by a line, so probably a line.
The hypothesis is best supported by this graph is the Cardinals’ food supply increased. Therefore option D is correct.
This can be inferred from the increasing trend in the number of cardinal chicks over time. As the food supply for cardinals increased, more chicks were able to survive and thrive, leading to an increase in the population of cardinal chicks.
The graph does not provide direct evidence or information about the population of cardinal predators, the feeding behavior of dominant cardinal chicks, or the spread of disease among cardinals.
Therefore, the most reasonable explanation based on the information provided is that the increased food supply contributed to the increase in the number of cardinal chicks observed in the graph.

When a lever rests on a fulcrum, a heavy object on one end of the lever can be lifted with less _____.
A. work
B. force
C. energy
D. resistance
Answer:
A
Explanation:
Work is a product of force and distance. In other terms, when the force applied on point result to movement, then work done is the force applied multiplied by the distance/displacement of the movement. Work is measured in Joules. In this case, work can be derived as W = Fs cos θ; where θ is the angle of displacement at the fulcrum.
Fungi can act as decomposers in the environment. Why is this inportant
Answer:
Fungi help in clear waste and dead material and provide nutrients to the plants.
Explanation:
Decomposers are very essential for any food web in an ecosystem. If there were no decomposers in any ecosystem, the autotrophs would not get important nutrients, and waste and the dead matter would pile up.
Fungi are the primary decomposer of litter in most of the ecosystem. They decompose dead, organic matter or waste by releasing various enzymes to break down the material. They absorb the nutrients form in the decaying material.
Hyphae are the part that breaks down and absorbs nutrients,
Thus, the fungi help in clear waste and dead material and provide nutrients to the plants.
Teddy is explaining to his class that hydrothermal vents form isolated ecosystems. Which point should he explain? A. The organisms of the hydrothermal vent do not interact with the organisms of different ecosystem. B. The organisms of the hydrothermal vent are a part of other food webs. C. There is a continuous input and output of energy and materials in the hydrothermal vent. D. Sunlight plays a vital role in the hydrothermal vent ecosystem.
Answer:
A
Explanation:
In such an isolated ecosystem, there is usually an autotroph species that coverts the abiotic elements in the environment to biotic elements. In a hydrothermal vent, it is likely that there are some chemoautotrophic bacteria that covert the sulfur and other chemicals in the water into organic molecules. This energy is then transferred up the food web in the closed ecosystem. In such an ecosystem, even the waste product of one life form may be utilized by another species.

Our body temperature will stay around 98.6 degrees, even when it is hot or cold outside. This is an example of:
A. A behavioral adaptation
B. Structural Adaptation
C. Homeostasis
D. Equilibrium
Answer:
Option C, Homeostasis
Explanation:
Homeostasis is a mechanism through which body maintain its state of stability/equilibrium. Thermoregulation is one of the mechanism of homeostasis by which body maintain its internal temperature. The average human body temperature is 98°F (37°C). When the external temperature increases, the body sweats or vassolidate to maintain the stable temperature.
When the external temperature decreases, the body undergo vasoconstriction or thermogenesis to main its average temperature.
Hence, option C is correct
