Allogeneic hematopoietic cell transplant is procedure in which a patient receives healthy blood-forming cells (stem cells) from a donor to replace their own stem cells that have been destroyed by treatment with radiation or high doses of chemotherapy.
An allogeneic hematopoietic cell transplant uses a donor's bone marrow or blood. The donor is usually a relative of the patient, although unrelated donors or umbilical cord blood are sometimes used.
Allogeneic stem cell transplantation involves transferring the stem cells from a healthy person (the donor) to the patient's body after high-intensity chemotherapy or radiation. The donated stem cells can come from either a related or an unrelated donor.

The right answer is D.
The absorption of molecules at the level of the skin is carried out by passive diffusion for the molecules of low molecular weight (lower than 400 Da), the skin being covered with a lipoprotein film rich in water by its stratum corneum, rendering it little-permeable.
This absorption may be variable according to factors related to the skin such as stratum corneum's thickness, the state of hydration, the presence of cutaneous lesions or individual variations.
External factors may also modulate percutaneous absorption such as contact time, iontophoresis or the presence of specific adjuvants.
The answer is <span>the number of DNA mutations in an organism is measured over time to determine how long it will take for a new species to evolve.</span>
Answer:
b. Increase in activity of glycogen phosphorylase.
Explanation:
Glycogen synthase exists in two forms which is phosphorylated form which is covalent modification of serine residues by ATP and dephosphoryated form which is obtained using phosphatase on phosphorylated form. Glycogen phophorylase catalyzes hydrolysis of glycogen which shortens glycogen molecules.
