Answer:
Category D drugs
Explanation:
There are five categories of drugs, they include: categories A, B, C, D and X. Research shows that category D drugs have possible fetal risks, however, the potential benefits on the mothers still outweighs the risk. An example of a category D drug is Losartan.
Category A drugs have no evidence of risk on fetus, an example is folic acid.
Category B drugs also show no adequate evidence of risk on the fetus. An example is metformin.
Evidences shows Category X drugs have an adverse effect on the fetus, hence the risk outweighs the potential effect. An example is Methotrexate.

<span>Endocrine glands are ductless or tubeless organs or groups of cells that secrete hormones directly into the bloodstream.</span> <span>The endocrine glands are part of the endocrine system and include the pineal gland, pituitary gland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, hypothalamus and adrenal glands. The endocrine system maintains homeostasis, controls the growth and development, controls metabolism (body energy levels), reproduction, response to stimuli (stress and/or injury).</span>
The name given to a group of similar cells that perform a special function together is tissue.
Answer:
A cell that has Damaged p53 gene , A) may become Cancerous; B) may experience uninhibited and out of control cell division; C) may accumulate multiple mutation.
Explanation:
- p53 gene is a tumor suppressor gene that encodes a polypeptide that acts as a transcription factor.
- Mutation in p53 is associated with 50% of human cancers.
- Loss of p53 removes DNA damage check point.
- Mutation in p53 prevents DNA repair and the apoptosis of cells that contain irreparable damage.
- as a result the cells may accumulate multiple mutations.
- Since Functional p53 promotes DNA repair and arrest the cell cycle if a damaged DNA is present; any mutation in p53 may result in uncontrolled cell growth and tumor formation.
