Answer:
The correct answer is -
1. totipotent
2 multipotent
3. pluripotent
Explanation:
The cells that are able to develop or differentiate a different kind of cells in the body of the individual are known as totipotent cells and this ability is known as totipotency. An example of such cells is found in the zygote.
Multipotent on the other hand are the cells that are able to develop into a specific kind of cell of tissues these cells are present and the example of this type of cell is adult stem cells. Whereas Embryonic stem cells are Pluripotent cells that are characterized as the cells that develop into any type of cell of the body of an organism.
Answer:
True.
Explanation:
The earth system is itself an integrated system, but it can be subdivided into four main components, sub-systems or spheres: the geosphere, atmosphere, hydrosphere and biosphere. These components are also systems in their own right and they are tightly interconnected.
It is possible to disrupt the plasma membrane by using enzymes and/or detergent agents.
<h3>What is the plasma membrane?</h3>
The plasma membrane is a lipid bilayer that is mainly composed of phospholipids and cholesterol.
In laboratory conditions, it is possible to disrupt this lipid bilayer by using detergent and proteins (enzymes) that break the bonds binding phospholipids.
For example, enzymes can break down the double bonds that bind fatty acids in the lipid bilayer.
In conclusion, the plasma membrane can be break down by applying enzymes and detergents.

Answer:
A source from which organisms generally take elements is called exchange pool (option B).
Explanation:
Options for this question are:
- <em>Food web.</em>
- <em>Exchange pool.</em>
- <em>Reservoir.</em>
- <em>Biotic community.</em>
The term exchange pool is related to the biogeochemical cycles that exist in nature, referring to the source from which elements present in the environment become part of living organisms.
<u>Exchange pools are the biotic components</u> -like animals and plants- of an ecosystem, which determine the passage of elements between living beings. An element can remain as a reservoir (abiotic) in the soil, and then be incorporated into the exchange pool.
