Answer:
B.) Gap junction
Explanation:
Plasmodesmata (singular form: plasmodesma) are intercellular organelles found only in plant and algal cells. (The animal cell "equivalent" is called the gap junction.)

Answer: C) variable base sequences and are variable in the population.
Explanation:
Single nucleotide polymorphisms (SNPs) result from mutations point and correspond to the position where there is an alternation of nucleotides A, C, G, T at a minimum allele frequency of 1% in a given population. The SNPs may be present in both coding and non-coding regions of the genome. In coding regions, when resulting in an amino acid substitution, they are called synonyms and can be conservative or non-conservative depending on the characteristics of the amino acids involved in the exchange. In such cases, modifications may occur in structural and functional proteins.
Answer:
an amino group and an R group
"Each of the 20 amino acids has a central carbon atom with four covalent bonds. These bonds link the carbon atom to an amino group ( NH2 ), a carboxyl group ( COOH ), a hydrogen atom, and an R group. The R group can be a carbon side chain, a hydrogen atom, or a functional group. " -------- from my textbook.
