A because idn hope u find the answer
Answer: There were less flies stuck to the model of the zebra with stripes.
Answer:
Researchers found that chronic exposure to a stress hormone causes modifications to DNA in the brains of mice, prompting changes in gene expression. The new finding provides clues into how chronic stress might affect human behavior.
Answer:
The correct answer would be- 1:1:1:1.
Explanation:
According to the question the cross between the two pea plants with the genotype RrYy and rryy where R for round seeds and r for recessive form that expressed wrinkled seed character. The other character of this dihybrid cross is the color of the seds Y for green and y for yellow seeds.
The cross is shown in the image attached that suggests that phenotypic ratio would be 1:1:1:1 as RrYy, Rryy, rrYy, and rryy.
Thus, the correct answer is : 1:1:1:1.
Given what we know, we can say that biology and neo-Darwinism both support the idea that natural selection explains how the environment selects organizations for survival or extinction.
<h3>Natural Selection. </h3>
- This concept is often summarized by the phrase "survival of the fittest".
- This refers to the ability of an organism to adapt to its environment.
- The better-adapted organisms will live to pass on their genetic information, thus changing the organization of the species.
- Those not able to do so will face extinction.
Therefore, since natural selection involves the survival or extinction of a species based solely upon their ability to adapt and change their genetic organization in response to their environment, we can say that this concept helps to explain how the environment selects organizations for survival or extinction.
