Answer:

A & C

Explanation:

The VDJ regions of immunoglobulins change a lot due to somatic mutations of the genes that code for these regions in the B cells of the immune system This is called somatic hypermutation and occurs in the lymphoid tissues. Most of these mutations will be deleterious while some will increase the affinity of a target. These effective immunoglobulins will be reserved in memory B cells and improve immunity against the target in the next invasion.

Somatic recombination (akin to genetic recombination in meiosis) – such as chromosomal translocations- also add to this diverse repertoire of the immunoglobulins because they increase the genetic diversity of lymphocytes and the type of Ig s they produce.

Flura [38]

Amount of carbon dioxide

Explanation:

The dependent variable in this experiment is the amount of carbon dioxide CO₂ produced by yeast during the experiment.

The independent variable is the cause in an experiment. It is the variable that causes the change we are measuring. In this experiment, the yeast is the independent variable. The yeast is producing the carbon dioxide.
The dependent variable is the effect in the experiment. It the variable changing in an experiment.
