If a researcher electrically stimulates the reticular formation in an animal, the animal will immediately wake up and be alert. Its purpose is to have some control of sensory signals and thus has the ability to alert the body when it is tired or needs to be awake.
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.

<h2>B) option is correct </h2>
Explanation:
Natural selection is a selection pressure which operates in a population and allow the best fitted genotype to survive in changing environmental conditions and eliminate the other genotype which are not fit
In artificial selection, breeders select superior breed for the breeding purpose so that this type of selection favors the superior genotype and eliminates inferior genotype, thus leading to genetic drift
Stabilizing selection is a type of natural selection in which intermediate genotype is favored but extreme genotypes (inferior and superior) are eliminated
In the given example of pigmentation in pigeons, breeding is selectively done with intermediate pigmentation hence intermediate genotypes will be favored
Answer:
This statement is true
Explanation:
Different substances such as growth factors and nutrients affect the mechanism of density-dependent inhibition of growth as cells become more and more numerous
Answer:
Deuterium, (D, or 2H), also called heavy hydrogen, isotope of hydrogen with a nucleus consisting of one proton and one neutron, which is double the mass of the nucleus of ordinary hydrogen (one proton). Deuterium has an atomic weight of 2.014
