Answer:
A scale and a tape measure.
Explanation:
Use the tape measure to get the volume and the scale to get the mass.
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.

Answer:
Asian continent specifically China and Korea country
Explanation:
The long horned beetle is native to the Asian continent specifically China and Korea country . These long horned beetles are long in size and can be easily identified because of their horns or antennae.
They feed upon the tree barks, branches and trunk and make them hollow or full of cavity. They also feed upon poplars, maples, elms and mulberries
This leads to structural weakening of trees
