A change occurs in an environment that lasts for several thousand years and causes changes to the genetic makeup of several species. What can be known about this change?

a. it is short-term

b. it is long-term

c. it involves an el Nino storm

d. in involves a la Nina storm

Answer: b. it is long-term

Explanation:

A long term change is the change in the biodiversity and the surrounding environment that remains for a long period of time. The affect of such change can be evident on the physical environment and on the living beings. For example, ice age, deforestation, mass extinction, and volcanic eruption.

The long term change is the correct option this is because of the fact that of the genetic makeup of the species changes it will remain the same for next generations and for thousands of years.

The correct answer is option B

A change that occurs in the environment and stays for thousands of years and causes change in the genetic makeup of species takes time.

The changes that occur at genetic level takes time as it takes several years to change the genetic makeup of the organism.

Hence, it is a long term process.
