Question

scientists believe that the bone structure of a cats leg, a humans arm, a whales flipper, and a bats wing are biologically similar. these similarities suggest that:○ these animals had a common ancestor○ these animals were all born at the same time○ these animals can only survive if they live together○ these animals have the same bone that is used to fly5 multiple choice 2 pointswhat process produces sex cells?○ meiosis○ mitosis○ respiration○ photosynthesis6 multiple choice 2 pointswhat is an organism called that has two different genes for a trait? (examples tt or rr)

Explanation:

1. For the first question: Similar bone structures (homologous structures) in different species are evidence of shared evolutionary ancestry.
2. For the second question: Photosynthesis is the biological process that converts light energy into chemical energy stored in glucose (a six-carbon sugar).
3. For the third question: An organism with two different alleles (genes) for a single trait is defined as heterozygous, represented by genotypes like Tt or Rr.

Answer:

1. these animals had a common ancestor
2. Photosynthesis
3. Heterozygous
