Anatural disaster caused a piece of land to break away from the mainland.

the landmass drifted away from the mainland and became isolated in the ocean.

the landmass has a small fraction of species that were present on the mainland, and only a few individuals of each species survived. what will happen to the biodiversity of the newly formed island?

a. the biodiversity will decrease because there are fewer species on the newly formed island.

b. the biodiversity will increase because the landmass is isolated from the island.

c. there will be no change in the biodiversity of the newly formed island.

d. the species on the island will likely have lower genetic diversity than the species on the mainland.

e. the species on the island will have a higher risk of genetic mutations because they’re now on an island.

it’s more than 1 answer.

The correct options are :

A)  The biodiversity will decrease because there are fewer species on the newly formed island.

D) The species on the island will likely have lower genetic diversity than the species on the mainland.

Explanation:

When a larger population is broken down and a smaller population is formed, the genetic diversity in the smaller population will be lower as it has fewer species. As a result, options for genetic variations will be lesser. Hence, the landmass which drifted away will have lower biodiversity than the mainland. There will be more number of species on the mainland hence the genetic diversity will be more there.

advantage of using stem cells in medical research:

1.       it provides medical benefits in the fields of therapeutic cloning and regenerative medicine.

2. it provides great potential for discovering treatments and cures to a variety of diseases including parkinson disease, spinal cord injuries, diabetes, alzheimer’s disease and many more.

3. limbs and organ could be grown in lab from stem cells and then used in transplant or treat illness.
