Answer:
Explanation:
It can be used to predict the outcomes of genetic crosses. How do geneticists use Punnett squares? They can be use to predict and compare the genetic variations that will result from a cross. Diagram showing the gene combinations that might result from a genetic cross.
The following are the statements that accurately demonstrate the electron transport chain:
1. The electron transfer in the electron transport chain is combined with the proton transfer from the matrix to the intermembrane space.
2. The prosthetic groups, like Fe-S centers, directly take part in the transfer of electrons.
3. The electron carriers in the electron transport chain comprise cytochrome C and ubiquinone (coenzyme Q).
4. The electron carriers are arranged into four complexes of prosthetic groups and proteins.
5. The reactions of the electron transport chain occur in the inner membrane of mitochondria.
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.
