A single human B cell can produce only D. 1 antibody.
It produces a single species of antibody, with unique antigen-binding site.
"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.
<span>Water has a surface skin. Some insects are able to generate tiny bubbles under their bodies which makes them buoyant enough to not break thru the water's skin. This skin is also known as surface tension. </span><span>Some bugs and small objects (pins or paperclips, etc) can rest on the surface of the water due to surface tension. Water molecules are bipolar and attract each other forming a skin. The bug or paperclip make tiny depressions in the water skin which provides buoyancy. A detergent will ruin the water tension (because it is a wetting agent) and the bug or paperclip will sink.</span><span>

"Human cells that contain one set of 23 chromosomes are called gametes, or sex cells; these eggs and sperm are designated n, or haploid. The matched pairs of chromosomes in a diploid organism are called homologous chromosomes."
Answer:
By spliting them up it would be most simular to how sex cells work with traits that produce 4 possible outcomes
Explanation:
