Answer: Option A
Explanation:
The hypothyroidism can be defined as the condition in which the thyroid hormone is not able to produce thyroid hormones.
The thyroid stimulating hormone is produced by the pituitary gland. This hormone functions by regulating the production of the hormones by the thyroid gland.
If there is an unusual amount of the hormones released by the pituitary gland there will be an abnormal amount of the TSH and TRH. The thyroid stimulating hormones cannot respond to the hormone released from the pituitary.
Hence, the correct answer is Option A.
It is called genetic engineering
Answer:
c. causes cells to swell and burst, whereas apoptotic cells shrink and condense
Explanation:
These two mechanism are responsible for death of cells in multi cellular organisms.Apoptosis is naturally occurring process which is well organised and programmed.It is ensures the automatic death of old and worn out cells, needed for certain cellular developments. This is demonstrated by DNA fragmentation,cell shrinkage,and the break down of the nuclear walls.It can be initiated through two pathways of intrinsic and extrinsic,The latter leads to death from internal factors,while in the former is when external factor causes the death .
However,when cell death is influenced by external factors(toxins) in the cell environments,which lead to unpredictable or unregulated process leading to cell death ,the process is called Necrosis.it is demonstrated with the swelling and busting of the cell.and characterised with inflammation. It is an accidental death which causes injuries to the cells and tissues.
