Shifting biomes could have consequences for the regions in which the shifts occur. Read the two cases below and decide which con
Nata [24]

Answer:

increased risk of wildfires- both

local economy suffers- Case 1

carbon storage decreases - Case 2

agricultural production decreases - Case 1

carbon storage increases -  Case 1

disease vector range changes - Case 2

decreased water availability - Case 1

local economy thrives - Case 2

species range changes - Case 2

Explanation:

Fires are common to  taiga biomes. Owing to the fact that the biome in case 1 changed from an agricultural community to a grassland and subsequently to a desert, agricultural productivity will decrease, the local economy will suffer, water availability is decreased and local economy suffers as a consequence of desertification.

On the other hand, in case 2, the diseases vector range as well as species range changes due to the change in the species of foxes from Artic foxes to red foxes that carry rabies. Carbon storage decreases as the taiga biome acts as a carbon sink. The local economy thrives due to timber production.

Lastly, species range changes both in case 1 and case 2 since there is a loss of species. Species range is the area where a particular species can be found during its lifetime. Certainly, the range of area where species are found changed in cases 1 and 2.

A elephant cell has 20 chromosomes. how many chromosomes will the cell have just before mitosis begins in the elephant cell?
lora16 [44]

The elephant cell will have 20 chromosomes.

Cells undergo interphase before getting to the mitotic phase. At the S phase of the interphase, the amount of DNA in the cell is double by replication. However, the number of chromosomes remains intact.

Thus, the cell gets to the mitotic phase with the same number of chromosomes that is usually present in normal vegetative cells of the animal.
