While looking at some seawater through your microscope, you spot the egg of an unknown animal. which of the following tests could you use to determine whether the developing organism is a protostome or a deuterostome? see whether the embryo ) exhibits spiral cleavage or radial cleavageb) develops a blastoporec) develops germ layersd) develops an archenteron

The correct answer will be option- A

Explanation:

The protostomes and deuterostomes are the classification of the animal kingdom based on the stages of embryological development.

In protostomes, the mouth develops from the opening called blastopore side whereas anus develops secondarily whereas, in the deuterostomes, the anus develops from the blastopore while the mouth develops secondarily.

This difference begins as a result of the cleavage pattern formed during the initial stages of the embryo that is in protostomes the cleavage pattern is spiral whereas in the deuterostomes the cleavage pattern is radial.  In the given question, one should look at their cleavage pattern and can classify the egg

Therefore, option-A is the correct answer.

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a

answer: collecting information/data

reason: the student is going around and asking people questions to collect data
