Members of two different species possess a similar-looking structure that they use in a similar fashion to perform the same function.
Which information would shed the most light on whether these structures are homologous or whether they are, instead, the result of convergent evolution?

a. The two species share many proteins in common, and the nucleotide sequences that code for these proteins are almost identical.
b. Both species are well adapted to their particular environments.
c. The sizes of the structures in adult members of both species are similar in size.
d. Both species reproduce sexually.
e. The two species live at great distance from each other.

a. The two species share many proteins in common, and the nucleotide sequences that code for these proteins are almost identical.

Explanation:

Homologous structures are structures that living organisms possess due to the fact that they shared a common ancestry. These structures could be in the form of organs or a skeletal part of the body.

Homologous structures for living organisms with a commonly shared ancestry do not have to look the same or perform the same functions.

Examples of Homologous structures are : The arm in humans, wings in bats and the flipper in whales. Humans, Bats, Whales share a common ancestry because they are mammals and they share many proteins in commone.

Also, the nucleotides that code for proteins found in the wings of bats, arms of humans and flippers in whales are almost identical.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.
