Protostomes develop a mouth first and then an anus. This is the difference between protostomes and deuterostomes.

In protostome development, there is a spiral radical and indeterminate cleavage. The blastopore becomes the mouth and the coelom forms from the mesoderm.

In deuterostomes development, radial and indeterminate cleavage takes place. The blastopore is the new anus and the coelom forms from budding off the wall of the archenteron.

6) What process is shown in the diagram
marusya05 [52]
Answer: B

Why? It is not A or D for many reasons but cell differentiation is used for very specific functions as cell determination is used for different embryonic functions. Based on the diagram I seems to me that it is not very specific so that’s why I think it’s B
(If it’s not be then is 100% C but B makes more sense)

Hope this helps

What is the answer with explaining
pychu [463]

Answer:

All EeWw (100%)

Explanation:

This question involves two genes; one coding for earlobes and the other for hairline. According to the question, one parent is homzygous recessive for earlobe but homzygous dominant for hairline i.e. (eeWW) while the other parent is homzygous dominant for earlobe but homzygous recessive for hairline i.e. (EEww).

The cross between the two parents is as follows: eeWW × EEww. The following gamete combination will be produced by each parent:

eeWW - eW, eW, eW, eW

EEww - Ew, Ew, Ew, Ew

Using this gametes in a punnet square, the following proportion of offsprings will likely be produced:

All EeWw
