Answer:

In plate tectonics, a divergent boundary or divergent plate boundary is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts, which eventually become rift valleys. The mid-Atlantic ridge is an example of a divergent boundary, where the Eurasian Plate that covers all of Europe separates from the North American Plate. This underwater mountain range is constantly growing as new crust is formed. Further up that same boundary, it passes through Iceland.

Arada [10]

Answer:

a. autotriploid of species A: 63 chromosomes

b. autotetraploid of species B: 96 chromosomes

c. allotriploid from species A and B: 1) 66 chromosomes and 2) 69 chromosomes

Explanation:

For a.

this species will have 3 haploid sets of chromosomes ('tri' means 3)

one haploid set = 21

21 × 3 = 63 chromosomes

For b.

this species will have 4 haploid sets of chromosomes ('tetra' means 4)

one haploid set = 24

24 × 4 = 96 chromosomes

For c.

there are two ways to do this:

1) two sets of chromosomes from species A and one from species B

42 + 24 = 66 chromosomes

2) one set of chromosomes from species A and two from species B

21 + 48 = 69 chromosomes

Hope that answers the question, have a great day!
