False. The statement is correct only in part
<span>The phospholipid molecule is simply bipolar, that is it has two ends that are opposed to each other in their characteristics.</span>
<span>This phospholipid molecule is said to be amphipathic which simply means it has both a hydrophilic and hydrophobic component.</span>
<span>The hydrophilic end, which is water loving, is the "head" of the molecule and is made of a phosphate group. The hydrophobic end which means water hating or fearing is the "tail" of the phospholipid and is made of two chains of fatty acids. </span>

Explanation:
G A T and C are all bits of DNA (deoxyribonucleic acid)
G stands for Guanine A stands for Adenine C stands for Cytosine and T stands for Thymine, when Guanine is in the DNA it always pairs with Cytosine creating G-C and the same is for Thymine and Adenine, when they are sequenced in such a way it just shows how the DNA is placed.
The brain and the spinal cord are the organs of the central nervous system.
"Down- regulation results in an increase in the number of target-cell receptors" statements is incorrect.
<u>Option:</u> B
<u>Explanation:</u>
The generation of gene products with the biological context of organisms: down-regulation is a mechanism by which a cell reduces the amount of a cellular product, such as RNA or protein, in accordance to an external stimulus, for instance, on type 2 diabetes, insulin receptors may be downregulated.
The supplementary process involving these component increments is called up-regulation. Enhanced uterine oxytocin receptors occur in pregnancy's third trimester, inducing a contraction of the smooth uterine muscle.
