D. Adults outcompeting offspring for resources
Answer:
B
Explanation: For example lions and cheetahs need similar resources so they compete with each other.
The the word competition mean in biology is C. Organisms from the same species looking for the same resource**.
What does the word competition mean in biology?Competition in biology is the interaction between organisms that are competing for the same limited resources. These resources could be food, water, space, or mates. Competition can occur between organisms of the same species or between organisms of different species.
When competition occurs between organisms of the same species, it is called **intraspecific competition**. Intraspecific competition can be very intense, as the organisms are very similar and have the same needs. For example, two male lions competing for the same female lion are engaging in intraspecific competition.
Competition is an important part of the natural world. It helps to regulate populations and ensures that the strongest and most adaptable organisms survive.

Which of the following would be a reason for species to undergo cyclic population changes?
Answer:
"The vegetation it eats increases and then decreases repeatedly with changing seasons" would be a reason for species to undergo cyclic population changes.
Explanation:
A keystone specie corresponds to an organism species which has disproportionately high environmental effects relative to its abundance or population.Many living organism population typically undergo cyclical shifts in size of population.
Cyclic oscillation leads to regular decline and fall across time in the population size of the living organism concerned.The cyclical population shifts are sometimes triggered by relationships between different organism populations. Disruptions in food availability, for an instance, may bring about cyclical shifts in population.

B. It moves into the atmosphere.
O
O
C. It goes back into the soil.
D. It is absorbed directly into animals.
Answer:
The correct answer is -It goes back into the soil.
Explanation:
Nitrogen is found in a wide variety in the atmosphere. It can be found in a form of ammonia,nitrate, nitrite, nitrogen dioxide, nitric oxide etc.After the death of a plant or animal body, the organic form of nitrogen is converted to ammonium by the microorganisms and this process is called as ammonification.Enzymes that are required for this conversion are GDH, Gln synthetase etc.A student observed several slides with different cell types under a microscope. What's Pair slides contain cells that result from meiosis.
Answer:
2.3.4
Explanation:
2.3.4
Final answer:
Slides showing cells from meiosis will depict stages where chromosome number is halved, with key events like crossing over occurring in prophase I and independent assortment during metaphase I. These processes are evident in other slides at various meiotic stages and can be further understood with interactive animations.
Explanation:
The slides that contain cells resulting from meiosis will show various stages of cell division where the ploidy changes from diploid (2 sets of chromosomes) to haploid (1 set of chromosomes).
This reduction in chromosome number occurs during meiosis I, specifically in the transition from telophase I to cytokinesis, resulting in two haploid daughter cells. During meiosis II, these haploid cells will undergo a division similar to mitosis to produce four genetically unique haploid cells.
Key processes like crossing over and independent assortment contribute to genetic diversity and occur during prophase I and metaphase I, respectively.
Crossing over involves the exchange of genetic material between non-sister chromatids of homologous chromosomes, which can be seen under a microscope as chiasmata. Independent assortment is the random distribution of homologous chromosome pairs to daughter cells.
To visualize these processes using a microscope, you could examine Lilium anther slides during different meiotic stages, draw and label each phase, and note where crossing over or independent assortment occurs.
The observation of homologous chromosomes aligning and separating during the meiotic stages can be further explored through interactive animations focusing on the meiosis process.

Answer: Atp stands for adenosine triphosphate. Its a molecule made in every cell of your body. It has three phosphates attached to it and the bonds of these phosphates are a large amount of chemical energy. For every single chemical process in your body that requires energy the cdllx of your body will break your bond between one of the phosphates.
Explanation:
Final answer:
ATP consists of three parts: adenine, a nitrogenous base; ribose, a five-carbon sugar; and three phosphate groups that store energy. The high-energy bond between the last two phosphates is broken to release energy for cellular processes.
Explanation:
Adenosine Triphosphate (ATP) is a complex molecule that serves as the primary energy carrier in the cell. The three parts of an ATP molecule include:
Adenine - a nitrogenous base imperative for the structure of ATP.Ribose - a five-carbon sugar that serves as the backbone to which the adenine and phosphate groups are attached.Three phosphate groups - referred to as alpha, beta, and gamma phosphates, these groups store the potential energy that is released during cell metabolism.The bond between the last two phosphate groups, beta and gamma, is known as a high-energy bond that, when broken, releases energy for cellular activities. This process is known as hydrolysis. The energy released is then used in various cellular processes, including muscle contraction and the synthesis of biomolecules.

Humans and hogs have differences in only 1 out of the 51 amino acids in their insulin proteins. Hogs and guinea pigs have differences in 17 out of the 51 amino acids in their insulin proteins.
What can be inferred from this information?
A.
Hogs and guinea pigs are more closely related to each other than either is to humans.
B.
Hogs are related to humans but not to guinea pigs.
C.
Humans are more closely related to hogs than hogs are to guinea pigs.
D.
Humans are related to guinea pigs but not to hogs.
Humans are more closely related to hogs than hogs are to guinea pigs.
Explanation:
The difference in the amino acid sequence of a protein is used to know the relation between organism i.e. how closely they are related.
It is known that proteins are the result of DNA sequence ie genes of the organism.
The gene or protein is compared between organisms to understand the evolutionary evidence and similarities between them.
The less is the difference the more is the two organisms closely related as in the case of hog and human which have only 1 amino acid difference in their insulin enzyme. While guinea pig is having a difference of 17 amino acids so it is expected to be distantly related.
These relations helps the scientist to resolve the issues of crisis say insulin. They zero out the possibility of extracting the enzyme genes of possible organism and increase the yield.

Which hormones most directly influence the uterus during pregnancy
Estrogens, progesterone, and human Chorionic Gonadotropin (hCG) are the main hormones that influence the uterus during pregnancy. First released by the corpus luteum, these hormones stimulate changes that nourish the embryo and maintain the pregnancy. As the gestation advances, the placenta takes over the secretion of these hormones, which continue to play vital roles in the healthy progression of pregnancy.
Explanation:The hormones that most directly influence the uterus during pregnancy are primarily estrogens, progesterone, and human Chorionic Gonadotropin (hCG). These hormones are firstly secreted by the corpus luteum during the initial weeks of pregnancy, resulting in the generation of decidual cells that nourish the early stage embryo, or blastocyst, before the placenta forms.
As the gestation progresses, the placenta becomes the primary endocrine organ, taking over the role of hormone secretion from the degenerating corpus luteum. Estrogen, progesterone, and hCG secreted by the placenta are responsible for most of the changes experienced during pregnancy.
For instance, estrogen mainly maintains the pregnancy and promotes fetal viability while also stimulating tissue growth in both the mother and fetus. Progesterone, on the other hand, prevents new ovarian follicles from developing and suppresses uterine contractions, protecting the developing fetus.
Lastly, hCG promotes the survival of the corpus luteum, stimulates the male fetal gonads to secrete testosterone necessary for the development of the male reproductive system, and ensures the placenta continues to secrete progesterone crucial to maintaining the pregnancy.

Light is the moving energy form that is made up of tiny particles known as photons.The light waves comprises of both magnetic and electric aspects hence known as electromagnetic.The process of propagation of light wave is : the fields vibrates perpendicularly in the same direction of propagation of the wave, and at 90 degree angle with each other.Similar to sound waves, light wave can interfere with each other.Diatoms and dinoflagellates have a variety of shapes. Why is their shape an adaptation for staying afloat as a phytoplankton?
Answer:
All species of plankton have certain characteristics in their shape which allows them to float in the water column. They have features such as stored fats, lateral spines, oil droplets etch which allow them to float in water. Almost, all of the diatoms and some species of the dinoflagellates are capable of carrying out the process of photosynthesis. Hence, these organisms are capable of making their own food.
Final answer:
Diatoms and dinoflagellates have adapted shapes that help them stay afloat in water. Diatoms form complex colonies, while dinoflagellates have cellulose armor and flagella for buoyancy and mobility. These adaptations ensure they remain in habitats conducive to their survival and roles as key components of the aquatic food web.
Explanation:
The variety of shapes found in diatoms and dinoflagellates serve as adaptations for staying afloat as phytoplankton. Diatoms, for instance, form colonies in shapes like stars and spirals, facilitating easier floating in the water column through raft-formation and making it harder for predators to engulf them. Dinoflagellates, characterized by their cellulose armor and two flagella that produce a spinning motion, enhance their buoyancy and enable their persistence in various marine and freshwater habitats. The interlocking plates of cellulose and the action of the flagella not only contribute to their floatation but also add to the diversity in morphologies that prevent them from sinking, ensuring they remain in light-rich, upper layers of water essential for photosynthesis.

Bacteria are the most common example of exponential growth. Select a number
between 2 and 10 to represent the hourly growth rate of a certain bacteria. For
example, selecting the number 8 would mean that the amount of bacteria will be 8
times greater after every hour.
In simple terms, Bacteria can be stated a large group of single-cell microorganisms and they can easily found everywhere which lack nucleus and organelles
Explanation:
The Bacterial growth can be stated as the multiplication of bacteria into two daughter cells and this process is stated as binary fissionIn simple terms, the exponential growth or rate of a bacteria is stated as the generation timeMostly bacteria will grow based on factors like air, temperature, etcFor example, E.coli takes around fifteen to sixteen minutes for growth and the bacteria coliform takes around twelve to twelve four hours depends upon the factorsFrom single cell of bacteria the number becomes, 2, 8, 64, ... and so on.
Explanation:
Bacteria is one of the best examples that show exponential growth.
The equation that shows the exponential growth of bacteria is
N = N₀ X 2ⁿ
If we consider the growth of the bacteria starts from 1 cell then,
N = 1 X 2⁰
N= 1
In 1 hour, the cell number becomes,
N = 1 X 2¹
N = 2
In 2nd hour, the cell number becomes,
N = 2 X 2²
N = 8
In 3rd hour, the cell number becomes,
N = 8 X 2³
N = 64
The growth continues exponentially and then becomes stationary after a certain period of time when enough nutrients are not present.
Thus from single cell of bacteria the number becomes, 2, 8, 64, ... and so on.
