1)organisms don’t all reproduce the same way. however, by comparing the of these organisms, many similarities between them are a)cells b)embryos c)mode of reproduction 2)of these organisms, many similarities between them are revealed. these similarities suggest that they’ linked. this type of study is called developmental biology

The correct answers are - B)embryo and evolutionary.

Explanation:

Organism reproduces differently by different modes of the reproductions. Reproduction of different group of animals are performed differently however by studying and comparing their embryos, many similarities can be found.

These similarities suggest that many organisms are diverged from a common ancestor and evolutionarily linked to each other.

Thus, the correct answers are - B)embryo and evolutionary.

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
