Helper T cells become activated by interacting with antigen presenting cells. and the second blank space is either cytotoxic t cells or B cells
Answer:
antidiuretic hormone
Explanation:
Osmosis is the tendency of a fluid, usually water, to pass through a semipermeable membrane into a solution where the solvent concentration is higher, thus equalizing the concentrations of materials on either side of the membrane. Antidiuretic hormone is also known as vasopressin. Vasopressin is a peptide hormone, synthesized in the hypothalamus and released by the posterior pituitary gland, that stimulates capillary muscles and reduces the flow of urine and increases its concentration.

The single mutation is in the B subunit of hemoglobin. one point mutation changed one amino acid and in malaria country the resulting trait, sickle cell trait, is very helpful to have in a heterozygous condition.
Hope this help:))
Answer:
The correct answer is option A) "The plasmid would not contain the human gene because the cuts are not compatible".
Explanation:
One of the basis of genetic engineering is to use the proper restriction enzymes to cut fragments of DNA. After cutting DNA with restriction enzymes most of the time the fragments have sticky ends, which are a few nucleotides that are one stranded and complementary to each other. Scientists take advantage of this characteristic and use the same restriction enzyme to cut genes and plasmid and later put it together with DNA ligases. If genes and plasmids are accidentally cut with different restriction enzyme it is very likely that the plasmid would not contain the human gene because the cuts are not compatible, since no sticky ends are generated.
