Answer:
The flow of individuals in and out of a population introduces new alleles and increases genetic variation within that population. Mutations are changes to an organism's DNA that create diversity within a population by introducing new alleles.

Answer:
The type of vesicular transport involved in the exporting of protein-based hormones, such as insulin, into the bloodstream is regulated exocytosis.
Explanation:
In general terms, exocytosis is a type of active transport that allows intracellular substances are released to the extracellular space, through of vesicles that fuse with the plasma membrane, which allow the exit of substances from inside the cell.
Regulated exocytosis is the specific vesicular transport for the secretion of substances, such as hormones. For this type of transport to exist, the presence of an extracellular signal is required, which will activate the fusion of the vesicles.
In the case of insulin, the external signal originates with the increase in blood glucose levels, a signal that penetrates the intracellular space and generates an increase in insulin production in the islets of Langerhans (pancreas).
Before insulin secretion occurs, the cell must be depolarized, allowing calcium to enter, which promotes transport by regulated exocytosis of insulin to the extracellular space.

The right answer is Watson and Crick.
The famous science journal "Nature" published an article of two pages, accompanied by one figure, titled "A Structure for Deoxyribose Nucleic Acid". Its authors are James Dewey Watson (24) and Francis Crick (36).
They synthesized the work of their scientific colleagues and were able to explain with a remarkable art of deduction how the DNA molecule contained in the cells of all living beings was duplicated.
