Biology
1 answer:
Luda [366]2 years ago
8 0

Explanation:

There are several types of antibodies and antigens, and each antibody is capable of binding only to a specific antigen. ... Antigens are bound to antibodies through weak and noncovalent interactions such as electrostatic interactions, hydrogen bonds, Van der Waals forces, and hydrophobic interactions.

Antibodies attach to a specific antigen and make it easier for the immune cells to destroy the antigen. T lymphocytes attack antigens directly and help control the immune response. They also release chemicals, known as cytokines, which control the entire immune response.

BRAINLIESTTT ASAP!!!!<br><br> -What is the position of Earth during its four seasons?
Keith_Richards [23]

Summer , for the northern hemisphere, summer is the warmest time of year. It's not because the planet is that much closer to the Sun, it's because the top part of the Earth is facing the Sun for a amount of time.

The Sun is directly over the Equator during the autumnal equinox, and heating the northern and southern hemispheres equally. As the northern hemisphere is moving towards shorter days and the cold winter, the southern hemisphere is watching the snows melt and the flowers bloom during their spring.

Summer is the season where the Earth is tilted way from the Sun and the South Pole is getting all of the light

Spring is a bit of a mirror image to our position in autumn. The Sun is directly over the Equator during the equinox and the northern and southern hemispheres
