What element is necessary for the production of thyroid hormone?

Biology
1 answer:
liubo4ka [24]3 years ago
8 0

Answer:

Iodine

Explanation:

This is a trace element needed for the  synthesis of the two thyroid hormone ; T4- thyroxine and T3-triiodothyronine. Four iodine molecules are added in T4 synthesis, and  three for T3 synthesis. Generally T4 is the major hormone produced, but  biologically transformed into active form T3.

Iodine majorly and selenium are the two trace elements needed for thyroid hormones synthesis. Therefore required amount of iodine is important in daily diet. iIn adequate supply of this leads to under production of iodine called hypothyroidism. poor brain development ( especially in kids),and goiter.

Sea foods . eggs, poultry seaweeds are rich sources of iodine.

Conversely, when  excessive amount is present in the blood, autoimmune thyroid diseases can occur,including cancer developments in the thyroid gland due to hyper cell activities.

You have gone into the field to take water samples from
timofeeve [1]

Answer:

Lake A: pH = 4.5; Lake B: pH = 7.5

Explanation:

I think that one because if you look on the acid vs base chart acid is from 0-6 and bases are from 8-14 and acids are less toxic, so you would infer that lake A has acid and lake B has bases.

i would have picked the ones closest to 7 ,which is neutral, but I'm not sure that a base can be lower then 7 so I didn't pick answer C

Which of the following are useful traits of cloning vectors?
SSSSS [86.1K]

Answer:

The correct answer is option - e. all of the above are useful traits.

Explanation:

A cloning vector is a small segment of DNA that can be established stably in an individual organism and able to internalize a foreign DNA for cloning purposes. The cloning vector could be taken from different organisms such as plasmid of a bacterium, or DNA from a virus. A cloning vector must possess some characteristics -  

The cloning vector must be self-replicating ability in the host cells, it should be small in size with restriction site for the restriction endonuclease enzymes in it. The replication character of the vector should not interfere with the internalized DNA fragment. The presence of marker genes in the vector is also a property that is helpful in identifying of recombinant cells.

Thus, the correct answer is option - e. all of the above are useful traits.

Each P1 parent of a monohybrid cross has completely identical genes<br> ture<br> false
lawyer [7]

Answer:

False.

Explanation:

Monohybrid cross may be defined as the cross done by taking the single character at the time. The monohybrid cross explains the concept of dominance and law of segregation.

The P1 parent of monohybrid cross doesnot have completely identical genes. This can be explained by the cross shown below:

Parent         Tt           ×       tt

Gamete         T  t           ×     t

Here, the parents are not identical.  

Thus, the answer is falsi.
