1c) If the amino acid sequences in the proteins of 2 organisms are similar, why will their DNA also be similar?
Trava [24]

Answer and Explanation:

Because the DNA sequence determines a protein's amino acid sequence, a gene shared by two closely related organisms should have similar, or even identical, amino acid sequences. That's because closely related species most likely diverged from one another fairly recently in the evolutionary span. Thus, they haven't had as much time to accumulate random mutations in their genetic codes.

Why is it imprtant for the ova and sperm cell to each contain a haploid number of chromosomes?
Katyanochek1 [597]

Meiosis makes sperm and eggs. ... The result is 4 haploid daughter cells known as gametes or egg and sperm cells (each with 23 chromosomes – 1 from each pair in the diploid cell). At conception, an egg cell and a sperm cell combine to form a zygote (46 chromosomes or 23 pairs).

Which of these statements best sums up evolution?
Ksenya-84 [330]

Evolution can be defined as the process of the change occurring in a population over a period of time through genetic variation. This genetic variation and the process of natural selection help a species to evolve by selecting the traits that helps it to better adapt to the environment. These genetic variations are inherited over time as the species continue to evolve.

Hence, the correct answer is 'change in population through genetic variation over time'.
