The right answer is A patient who is Rh– can receive only Rh– blood.

The blood group is not the only thing that matters, it adds a category: rhesus. Rhesus refers to a red blood cell antigen that is on their wall. There are two blood group systems: Rh positive (Rh +) and Rh negative (Rh-).

Rhesus is positive in people who have this antigen. It concerns the majority of the population. Negative rhesus refers to people without the antigen. This rhesus factor is especially useful to know if a blood transfusion is feasible between two people.

The blood transfusions can be "iso-rhesus", that is to say between Rh + and Rh- but only in one sense: Rh- can give to Rh + but Rh + can not give to Rh-. Again because of the presence of antibodies directed against the antigen in Rh- people.

Yes it is important to know a person's Rh factor, but you can give an Rh+ patient Rh- blood only once because after that their body will build a defense mechanism against it and the blood will be rejected the second time.

Steroid hormones bind to receptors in the nucleus of their target cells. cannot diffuse through cell membranes. remain in circul
goldfiish [28.3K]

Answer:

The correct answer is - bind to receptors in the nucleus of the target cells.

Explanation:

Steroid hormones are the chemical compounds that are a member of the class of steroids and act as hormones. These hormones are released by the adrenal cortex, testes and ovaries in the body placenta also release steroid hormone during pregnancy.

The steroid hormones do not bind to the plasma membrane of the target cell but binds to the receptors present on the nucleus of the cell. These cells pass through the cell and reach the nucleus and bind to it or gene to produce proteins for the biological process.

Thus, the correct answer is - bind to receptors in the nucleus of the target cells.

Which form of water motion commonly causes natural disasters along shorelines
lesya [120]

Answer:

water motion that is non-linear in nature can cause natural disasters on shorelines.

Explanation:

these natural disasters could be on a small scale or a large scale depending on the strength of that movement of water. Rip currents and storm surges (uncommon) are two different types of hazards that can occur on the coast. In addition, a more dangerous case is a tsunami - which may be triggered by an earthquake - these are ocean waves traveling at a very high speed.

Hope that answers the question. Have a great day!
