Answer:
(Choice B )
Explanation:
Neurons and muscle cells contain the same proteins, but the cells are different due to their locations in the body.
Answer:
Sensitization.
Explanation:
Hypersensitive reaction may be defined as the exaggerated or hyper response of the immune system. Hypersensitive reactions can occur due to auto immunity and allergies.
Type I hypersensitive reaction is mainly mediated by IgE antibodies. The sensitization towards particular stimuli like pollen grains may exaggerate the Type I hypersensitive reaction.
Thus, the correct answer is option (1).
Cell membranes are first proposed to be composed of phospholipid bilayers by Singer and G. Nicolson.
<h3>What do you mean by cell membrane ?</h3>
A cell membrane, often referred to as a plasma membrane, is present in every cell and serves as a barrier between the interior of the cell and the outside world. The cell membrane is a lipid bilayer that is semipermeable. The passage of chemicals into and out of the cell is regulated by the cell membrane.
- As a result, the cell membrane has two functions: first, it acts as a barrier to keep the cell's components in and undesirable substances out, and second, it acts as a gate to allow the entry of essential nutrients and the exit of waste products.
