The true statements about he T cell receptors are 1, 2 and 4.
T cell receptors are the molecules found on the surface of the T lymphocytes. V(D)J recombination is the unique mechanism of genetic recombination that occurs only in the lymphocytes during the early stages of T and B cell maturation resulting in the T cell receptors. They recognize antigen fragments bound to MHC molecules. Majority of the T cell receptors consists of an alpha chain and a beta chain and a few with gamma and delta chains. Each chain is composed of a variable and a constant region. Within these chains are the complementary determining regions (CDRs) which determine the antigen to which the T cell receptor will bind.

The statement is true. This phenomenon is called reactive
hypoglycemia, or more commonly known as sugar crash. This is due to abnormal
levels of blood glucose after consuming a large amount of sugar. This causes rapid
insulin secretion, thus, rapid glucose uptake by the tissues. The sudden fall
of glucose in the blood causes the sugar crash, which can be described as a
feeling of lethargy or tiredness.
Both Karl and Jose are likely to get sick this time since Jose's vaccine was dead, but neither will get it again once they acquire active immunity.
Karl will get sick and Jose will not this time, but neither will get this influenza again since they both will have acquired active immunity to it.
Karl will get sick and Jose will not this time, but Jose will be more likely to get it later since his immunity will be less recent than Karl's.
Both Karl and Jose will get sick this time since Jose's immunity has had time to wear off, but Karl is more likely to get it again since he has only been exposed once.
<u>Answer</u>:
Femur diaphysis and epiphyseal ends is made up with cortical bone and contains bone narrow. It is in the middle tabular part and composed with compact bone and central marrow cavity is situated around it. It is round in shape and a long bone. It is the origin of the attachment of many muscles as well as ligament.
The femur is the longest bone which is present in our thigh and also call as thigh bone. The division of femur can be divided into shaft, proximal and distal. In some aspect it is the strongest bone of our body and it helps in any activities.
