How does natural selection change the frequency of genes or traits over many generations? biology students conducted an experiment mimicking genetic variation and coloration. students used different colored beans to represent animals that might be prey: mice, for example. a student in each group was the predator: a hawk. beans (mice) were randomly scattered on multicolored floor tiles, each color within four tiles. the hawk collected mice (beans) for 10 seconds. mice not eaten reproduced. three generations of data a shown in the table.

speckled and striped beans (mice) had the best survival rates. why?

a) they reproduced very rapidly.
b) coloration was a form of camouflage.
c) they mimicked other mice and were spared.
d) the speckled and striped beans had a wider range.

give support for your answer! if not how did you find the answer?

The answer is; B

The stripped and speckled beans camouflaged the tiled floor and were not easily spotted by the ‘hawks’ (students). Therefore they were not ‘preyed on' (collected) as much as the other colored 'mice' (beans). This means they were more likely to reach reproductive age and pass down their genes to the next generation.

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air

explanation:

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
