How do T-cells work to recognize invading cells or molecules?​

Biology
1 answer:
yanalaym [24]3 years ago
5 0

Answer:

Antigen-presenting cells show digested antigens to T cells through the MHC on their surface, which allows the T cell to “see” the antigen and recognize it as foreign. The connection between the MHC and the receptor on the T cell is the first signal necessary to activate the T cell to respond to a tumor and destroy it.

Air at 1 atm was closed into a rigid container. It was then heated to a temperature of 911
otez555 [7]

Answer:

Final temperature, T2 = 2460 Kelvin.

Explanation:

Given the following data;

Initial pressure = 1atm

Final pressure = 2.7atm

Initial temperature = 911K

To find the final temperature, we would use Gay Lussac's law;

Gay Lussac law states that when the volume of an ideal gas is kept constant, the pressure of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Gay Lussac's law is given by;

PT = K

\frac{P1}{T1} = \frac{P_{2}}{T_{2}}

Making T2 as the subject formula, we have;

T_{2}= \frac{P_{2}}{P_{1}} * T_{1}

Substituting into the equation, we have;

T_{2}= \frac{2.7}{1} * 911

T_{2}= 2.7 * 911

Final temperature, T2 = 2459.7 ≈ 2460 Kelvin.
