what is the relationship between allele frequency's and a gene pool.
what is the function of each stage of meiosis?
Answer:
Before the cell enters meiosis, the chromosomes in a cell are duplicated (during the interphase). In meiosis I, the chromosomes condense along the center of the nucleus and pair with their homologues during crossing over. Next, the pairs of chromosomes separate and move to opposite ends of the cell.

Most trees do 'slow down' during winter, and deciduous trees that lose their leaves shut down photosynthesis entirely. Trees with needles (evergreen trees) that are retained over winter can actually photosynthesize during the winter.#Let's Study

Which of the following best describes why in general there are more hares in the ecosystem than foxes.
In 1945 there was a major event that caused the number of hares to dramatically increase. That is why there continues to be more hares than foxes here.
Hares are a lot smaller than the foxes, so more of them can fit into different niches. They can hide better in all of the bushes and behind rocks.
This is because if only 10% of the energy gets passed on to the next trophic level, then you need to have more lower level animals available to support the animals higher up the food chain. The fox must eat several hares to gain enough energy for growth and development
Answer:
C
Explanation:
The reason why there are more hares than foxes in the ecosystem is because if only 10% of the energy gets passed on to the next trophic level, then you need to have more lower level animals available to supports the animals higher up the food chain. The fox must eat several hares to gain enough energy for growth and development.

Which of these causes evolution?
A. Random mating
B. Natural selection
C. No mating at all
D. Extremely large population sizes
Natural selection causes evolution. The correct option is B.
What is natural selection?Natural selection refers to the process that leads to the adaptation of organisms to their environment.
Natural selection forces either select for or against traits. Traits that aid organisms in adapting are selected for, while those that do not aid in adaptation are selected against.
Traits that are selected for are allowed to perpetuate in the population while those that are selected against gradually fade from the population.

how can a rare trait be dominant
Answer:Just because a gene is dominant, and it takes just one translated allele for the trait to appear, doesn't necessarily mean that it's a physical trait that you'll see frequently in the population. Some dominant genes are rare, meaning that a small subset of humans have the dominant allele.

Under ideal conditions, how do allele frequencies change over time?
A. The frequency of the recessive allele increases in each generation.
B. The allele frequency does not change from one generation to the
next.
C. The frequency of the dominant allele increases in each generation.
O D. The alleles eventually reach a 50/50 balance.
The frequency of the dominant allele increases in each generation. Thus, the correct option is C.
What is natural selection?Natural selection is a process in which more environment-adapted organisms tend to survive and reproduce more frequently than less environment-adapted ones.
Because rare alleles are typically found in heterozygotes, the initial increase in frequency of a rare, advantageous, dominant allele is faster than that of a rare, advantageous, recessive allele. Therefore, natural selection won't be able to "see" a new recessive mutation until it is prevalent enough to manifest in homozygotes.
Once a population is in Hardy-Weinberg equilibrium, its frequency distribution won't vary from generation to generation.
