The type of cell division observed in the Figure is Meiosis. It can be deciphered by the presence of recombination between homo-logous chromosomes.

Why is mechanical digestion and important to chemical digestion
dangina [55]
They are both important because mechanical has to do with physical - cause mechanical means physical, so chewing your mouth is physical (you break your food into smaller pieces physically). And then chemical digestion is when food and saliva mix together. They happen when breaking down food into nutrients - enzymes. Enzymes are important for that process, because they make a nutrient.

During which phase are gametes preparing to divide
Sauron [17]
The answer is... Before entering meiosis I, a cell must first go through interphase. This is the same interphase that occurs before mitosis. The cell grows, copies its chromosomes and prepares for division. And to make it more simple the answer is meiosis. Hope this helps!
