Answer:
D) natural selection is generally limited to modifying structures that were present in previous generations and in previous species
Explanation:
A proficient engineer can easily design skeletal structures that are more functional than those currently found in the forelimbs of such diverse mammals as horses, whales, and bats. The actual forelimbs of these mammals do not seem to be optimally arranged because natural selection is generally limited to modifying structures that were present in previous generations and in previous species.
Not regally sure about this question I’m stuck on this one to
A. they both have prophase and metaphase. Mitosis and meiosis have the same steps, just a few of the steps are different, and in meiosis the steps are done twice.
1/4 or 25% will have the homozygous recessive genotype. 25% will have the homozygous dominant phenotype. 50% will be heterozygous. We would use a punnet square to figure this out. I’ve attached a picture of one to help you
Nope! it's just a commercial slogan.
