Which of the cells are involved in graft rejection?
Aleks04 [339]
T cells
The immune response to a transplanted organ consists of both cellular (lymphocyte mediated) and humoral (antibody mediated) mechanisms. Although other cell types are also involved, the T cells are central in the rejection of grafts. The rejection reaction consists of the sensitization stage and the effector stage.

A transmembrane protein has the following properties: it has two binding sites, one for solute A and one for solute B. The prote
Usimov [2.4K]

Answer:

The protein is a symport protein.

Explanation:

Transport proteins are proteins which are involved in the transport of solutes across the cell membrane. The binding of the solute to be transported across the membrane causes a conformational change in the shape of the protein, thereby moving the molecule to the side of nthe membrane it is to be transported. The difference in the concentration of the solute across the membrane known as concentration gradient is mainly responsible for the transport of molecules by the transport proteins.

There are three types of transport proteins: uniport, symport and antiport transport proteins.

Uniporters are involved in moving only one molecule across a membrane

Symporters are involved in moving two or more molecule across a membrane in the same direction.

Antiporters are involved in moving two or more molecule across a membrane in opposite directions.

From the description of the transport protein in the question, both solutes A and B are moved across the membrane simultaneously in the same direction. Therefore, the protein is a symport protein.

Any time a scientific theory is challenged, it means it's not a good theory.Do you agree with this statement? Explain
vfiekz [6]
False. Any time a scientific theory is challenged, it means it's not a good theory. And this statement is not valid. In theoretical models, they are revisited when there are further studies and discoveries found in a certain area where they can be remodeled and reintegrated instead of disregarding its credibility. Models, theories and paradigms are not challenged but rather encouraged, they are supported in many studies since these theories and models were created in order for us to understand a certain phenomenon but it would likely help the scientific society to be updated in the new forms or spheres of improvement rather than discouragement.

kupik [55]

Answer:

Air mass can be described as the volume of air present and the temperature of that mass of air.

Polar air masses are cold. They have less moisture content. The temperature of Maritime Polar air mass ranges from above freezing to below 70 degrees F.

Tropical air masses can be described as air masses that are warm and have a high moisture content. Temperature ranges between 70 degrees F to 90 degrees F.
