Crossing over occurs,leading to genetic variation in the daughter cells.

PLEASE HELP THEIR JUST TWO SMALL QUESTIONS!!!!!
Vsevolod [243]

Answer:

I did some research for you and I found this. I hope it helps you.

Explanation:

"Continental drift and sea-floor spreading became widely accepted around 1965 as more and more geologists started thinking in these terms. By the end of 1967, Earth’s surface had been mapped into a series of plates (Figure 10.16). The major plates are Eurasia, Pacific, India, Australia, North America, South America, Africa, and Antarctic. There are also numerous small plates (e.g., Juan de Fuca, Nazca, Scotia, Philippine, Caribbean), and many very small plates or sub-plates. For example the Juan de Fuca Plate is actually three separate plates (Gorda, Juan de Fuca, and Explorer) that all move in the same general direction but at slightly different rates."
