Kinetic energy is an expression of the fact that a moving object can do work on anything it hits; it quantifies the amount of work the object could do as a result of its motion. It can be calculated as:
KE = mv^2 /2
We calculate the problem as follows:
KE = mv^2 /2
400 = m(20)^2 / 2
m = 2 kg
Answer:
The correct option is;
Protein
Explanation:
Stress proteins are the class of proteins used to mediate cellular stress response. There are two types of stress proteins including the stress activated proteins and the dual functioning, stress response and cell function protein. By being a primary source of survival of cells under stress has resulted in the conservation and associated existence of the similar stress proteins in different classes of living organisms.
Naive t cells encounter antigen and activate, eventually leaving this compartment as an effector t cell at dendritic cells in lymph tissue (lymph nodes and spleen).
<h3>What is T-cell activation?</h3>
They are a type of white blood cell. T-lymphocytes are the part of the immune system and develop from stem cells in the bone marrow however they develop fully in thymus and leave after maturation. They help in protecting the body from infection and may also help fight cancer. They are also known as T cell and thymocyte.
T-cells get mobilized when they encounter a cell (dendritic cells or B-cells) displaying antigenic peptides bound to its MHC molecule. This MHC-antigen complex activate T-cells receptors and the T-cells start secreting cytokines.
some T-cells become helper T-cells and attract fresh macrophages, neutrophils and other lymphocytes and other cytokines to direct them at the site of action while some T-cell become cytotoxic and track down the virus infected cells.
