Sagot :
A crab responding to low oxygen levels in the environment by increasing the quantity of oxygen-binding pigment in its blood is an example of a phenotypic change.
The correct option is b.
Hemoglobins, hemerythrins, and hemocyanins are the three categories of oxygen-transporting proteins that may be separated in nature based on the active site.
In reaction to low oxygen levels in the environment, a crab increases the quantity of oxygen-binding pigment in its blood. This cannot occur unexpectedly. It is a change in phenotype.
A cell or organism can change from one phenotype to another, or two cells or organisms might exhibit distinct phenotypes despite having the same genotype. This process is known as phenotypic change.
Because phenotypic variations may result from changes in the long-term programming of gene activity rather than variation in gene sequences per se, studies of the foundation for inter-individual phenotypic variability should consider epigenetic variants in addition to genetic sequence polymorphisms.
