Ascientist looked at a group of embryos. upon examination, she observed that species a and b diverged closer to fertilization. she also observed that species c and d diverged closer to birth. which of the following statements is true?

a. species a and b are more closely related than species c and d.
b. species c and d are more closely related than species a and b.
c. species a and c are related.
d. species b and d are related.

B. Species C and D are more closely related than species A and B.

Explanation:

As you can see in the question above, in relation to embryos, species A and B diverge closer to fertilization. Thus, all embryonic development of these species occurs in different ways and with little or no relationship.

On the other hand, embryos of species C and D diverged closer to birth, which means that all embryonic development was similar and had close factors, which may indicate that these species are more closely related, genetically speaking, than species A and B.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.
