Answer:
you expect to see that 75% of your F2 generation rabbits have floppy ears and 25% of your rabbits have black fur.
Explanation:
<u> Available data:</u>
- Two true-breeding groups of rabbits.
- The first group has floppy ears and white fur.
- The second group has straight ears and black fur.
- 100% of the F1 generation has floppy ears and gray fur.
- Each of these traits is determined by a single gene and undergo independent assortment.
Having this information we can infer that floppy years, expressed by F allele, might be dominant over straight ears, expressed by f allele. And that the fur color is affected by incomplete dominance, being B the allele expressing black color, b the allele expressing white color and Bb the genotype for grey color.
Incomplete dominance is a condition where neither of the alleles completely dominates over the other one. Descendents possess an intermediate phenotype between the two parental phenotypes and not the dominant one.

Answer:
The predation pressure increases mate
Explanation:
Since the observation of the scientist goes in order to increase the coloration in males, because of the predation pressure, and as a consequence the females are attracted by this colored mates.
It will be expected that the increase in pressure, it will increase the colored in skin, and this could end in an increase of the number of mates per male.
Answer: When a cat drops from a tree to the ground, the conversion of gravitational potential energy to kinetic energy takes place. Then runs up behind a mouse to obtain its food. After eating its prey, the conversion of chemical energy to mechanical energy takes place inside the cat's body.
Explanation:
Answer: The presence of small amounts of heat-trapping greenhouse gases in the atmosphere warms Earth's surface, resulting in a planet that sustains liquid water and life. Changes in climate conditions can affect the health and function of ecosystems and the survival of entire species. Changes in Earth's system affects the growth of life on Earth. ... Life on Earth includes all the living things such as plants animals humans microbes etc. All take part in different cycles such as carbon cycle and nitrogen cycle and can influence global climate by changing chemical composition of atmosphere.
