tatuchka [14]

During T cell maturation, the t cells must pass two tests. first, immature t cells that can recognize MHC molecules are Selection. Second, immature t cells that recognize and bind to molecules normally found in the body are Activation.

Selection is the first test that T cells must pass. During this process, immature T cells that can recognize MHC molecules are selected. MHC molecules are found on the surface of cells and are involved in antigen presentation. When T cells come into contact with MHC molecules, they are able to recognize the molecules and begin the process of selection. During selection, the T cells that recognize MHC molecules are chosen over those that do not. This helps ensure that the cells that are selected are those that can properly respond to antigens.

The second test that T cells must pass is activation. During activation, T cells that recognize and bind to molecules normally found in the body are selected. These molecules are called self-antigens and can include proteins, carbohydrates, and lipids. When T cells come into contact with self-antigens, they are able to recognize the molecules and begin the process of activation. During activation, the T cells that recognize self-antigens are chosen over those that do not. This helps ensure that the cells that are selected are those that will not attack the body’s own cells.

Why do scientists dispute the claim that the Loch Ness monster is a real creature?​
Sauron [17]

Explanation:

Scientist disputes the claim that the Loch Ness monster exists beyond folklore because no one has truly seen them. Loch Ness monster in Scottish folklore is a monster that resides in the Scottish highlands in Scotland.

Scientists follow methods to substantiate a claim. A body of evidence must be available to justify an observation in the scientific realm.

No clearcut picture of the monster has been taken.

The monster is merely a folklore myth just like dragons.

Science does not work with hearsay and claims that cannot be substantiated and proven.
