<span>Mitosis is a process of cell replication because in this process a parent cell will double its content (DNA,organelles, cytoplasm) and then separate them in to two identical cells. The replication is </span><span>the ability of a cell making two exact replicas of its DNA.
Another example of cell replication is meiosis.

Answer:
a:Triploblastic, pseudocoelomate, protostome
Explanation:
When it comes to embryonic tissue layer in animals, some have two while some have three. Those with two layers are diploblastic while those with three layers are said to be triploblastic.
Body cavity evolution also vary in animals according to their development levels. Some animals lack body cavity totally and are referred to as acoelomates, some have a mesoderm-like fluid filled cavity and are referred to as pseudocoelomates while others have true body cavity with peritoneum and are referred to as coelomates.
During embryonic development, the mouth is formed first in some animals and they are referred to as protostomes while those in which the anus are formed first are referred to as deuterostomes.
<em>Hence, the best terms that describe the animal in question are triploblastic, pseudocoelomate, protostome.</em>
The correct option is A.

The human genome has been estimated to have 20,000 - 25,000 human protein - coding genes.
Before it was thought that the number of genes in the human genome was about 100,000, but with better and more advanced gene finding technology, this number has been revised down to the current estimate, and could continue to drop further.
The human genome has 23 chromosome pairs with a total of about 3 billion DNA base pairs. There are 22 autosomal chromosomes plus the sex determining X and Y chromosomes, to make 23 pairs.
