Answer:

c. Cold front

Explanation:

Cold fronts are bodies of air with cooler temperatures than the surrounding air. The general effect cold fronts have is that they cause a drastic change in the weather. This is because when they interact with the warmer air, they produce precipitation.

The storm most likely, came with an advancing mass of cold air, which caused the dramatic drop in temperature that was experienced. This is what is known as a cold front.

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:

<u>For a.</u>

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

one haploid set = 21

21 × 3 = 63 chromosomes

<u>For b.</u>

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

one haploid set = 24

24 × 4 = 96 chromosomes

<u>For c.</u>

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!
