True or false? in host-versus-graft rejection, the recipient recognizes the donor tissue as foreign and rejects the transplant;
snow_tiger [21]
The statements above are true;
In a host-versus-graft rejection the recipient's immune system recognizes the donor's tissue as foreign and rejects the transplant. On the other hand, in a graft-versus-host rejection, the donor tissue recognizes the recipient's tissue as foreign and the transplant rejects the recipient, causing destruction of the recipient's tissue and possibly death. Its important also to note that there are two types of rejection, the acute rejection, where the rejection of transplanted tissue that occurs several weeks after transplant. it is delayed hypersensitivity reaction, and the chronic rejection is a rejection of transplanted tissue that can occur at a late time. Immune complexes form in the arteries supplying the graft, choking off the blood supply and the tissue is rejected.

The cells in this part of a plant form long, vertical tubes. What is the most
3241004551 [841]

Answer:

D. The tubes allow water and nutrients to be transported throughout

the plant.

Explanation:

option D supports the description of the cells. The long , vertical tubes transport water and nutrients and are most likely xylem and phloem vessels.

option A is wrong since, chloroplasts inside the cell helps in absorbing sunlight.

option C is also wrong, because water loss is controlled by the stomata in the leaves and they are not long tubes.

option B could possibly be right but option D is better suited.

The monarch butterfly can be found in a wide range of areas across Canada and the northern United States during the spring and
hichkok12 [17]

In order to survive the winter, monarch butterflies "migrate to warmer areas".

<u>Option: B</u>

<u>Explanation:</u>

  • The survival for Monarch butterflies is not possible in any of the United States 'cold winters, therefore they are needed to migrate south and west every autumn to avoid the cold temperatures.
  • This species migration usually begins around every year in October, but may begin quicker if the weather turns cold earlier than that.
  • Thus they spend their winter hibernation all year round in Mexico and some areas of Southern California where the temperature is warmer.
  • If the monarch stays in the Eastern states, typically east of the Rocky Mountains, then they will migrate to Mexico and hibernate in <em>oyamel fir</em> trees.
