Answer: is D. Mercury was used to treat many illnesses long ago, and after being deemed safe by modern doctors its use has increased in the past 100 years.
Explanation:
The answer to your question is the first choice or choice A. Bacteria is a decomposer. That would be the only valid choice. If the question didn't say decomposer then all of these choices would be correct, but because it only says decomposers, bacteria would be the correct choice.
Prokaryotes don't have a nucleus, Eukaryotes have a nucleus as well as organelles, they perform functions together with other specialized cells where prokaryotes can be individual and functioning organisms.
Protons carry a positive electrical charge and they alone determine the change of the nucleus and changes the atoms atomic number
The question is incomplete, the complete question is;
Penetrance and expressivity are related to
A. the expression of a dominant phenotype in a heterozygote.
B. the increased expression of a particular trait when a hybrid species is formed.
C. the expression of one gene masking the effects of another gene.
D. quantitative traits that diminish or intensify a particular phenotype.
E. the influence of environment on the expression of a particular genotype.
Answer:
the influence of environment on the expression of a particular genotype.
Explanation:
In genetics, we define penetrance as the proportion of individuals in a given population carrying a particular gene/allele which leads to the expression of the particular trait associated with that gene/allele.
Expressivity is defined as the degree of expression of a given phenotype by individuals who possess a particular genotype. Expressivity shows the extent of variation in expression of genes by individuals having a particular genotype.
Both penetrance and expressivity has to do with the influence of environment on the expression of a particular genotype.
