Hi, it has to be a.):
The ribosomes are RNA-protein complexes that carry out the protein synthesis in cells
The rough endoplasmis reticulum is covered with ribosomes, which produce membrane proteins and proteins for secretion. The smooth ER is involved in the production of lipids, such as phospholipids for the membranes.
In the Golgi apparatus, the proteins get posttranslationally modificated by adding oligosaccharides to them(glycosylation), this oligosaccharides get assembled there, so this probably counts as producing new molecules

Answer:
A cell is a mass of cytoplasm that is bound externally by a cell membrane. Usually microscopic in size, cells are the smallest structural units of living matter and compose all living things. Now put that into your own words.
Explanation:
Answer:
B. Mutation; C. Random genetic drift; D. Migration; F. Natural selection
Explanation:
B. Mutation: Mutations resulting from substitution, addition or deletions of a nucleotide in a sequence can alter the gene. This can be carried over a population and may be have deleterious effects or increase fitness in a gene.
C. Random genetic drift: It is a change in allele frequency that occurs by chance, usually in a small population and is carried over generations.
D. Migration: Involves the flow of a gene in or out of a population, and this modifies the allele frequency.
F. Natural selection: When fitness-promoting alleles are favored and carried over to the next generation.
