T cells and B cells are the two main cell types that are crucial to the efforts of the adaptive immune response, in addition to cytokines and APCs.

<h3>Passive immunity is conferred by which of the following?</h3>

By supplying antibodies or lymphocytes that have already been produced by an animal or human donor, a vaccination may also impart passive protection. Most vaccines are administered parenterally (by injection), although some can also be taken orally or even nasally (in the case of flu vaccine).

Monoclonal antibodies search for and bind to the spike protein that protrudes from the coronavirus that causes COVID-19 after they have entered your body. Monoclonal antibodies that bind to the spike protein can prevent the virus from entering cells, slowing the infection.

The endothelial cell glycocalyx, which serves as a molecular sieve, and pressure gradients in the capillary beds both affect how lymph fluid is formed. toward with fluid propulsion

Astronauts experience similar feelings of dizziness and disorientation upon arrival in space and upon their arrival back on Eart
nordsb [41]

The correct answer is (b)The vestibular sense may be capable of sensory adaptation

Astronauts experience similar feelings of dizziness and disorientation upon arrival in space and upon their arrival back on Earth because the vestibular sense may be capable of changing adaptation. The dizziness and disorientation is due to the floating fluid in inner ear around zero gravity and it goes right away after some time when the astronauts reach the space. The adaptation is done by the brain to ignore the signals of the ear; the feeling this sensation for sometime the brain becomes adaptable and does not listens to the inner ear every time. This is a kind of sensory adaptation.

Why is the Copernican Revolution significant? Check all that apply.
sveta [45]

Few advancements in scientific knowledge were made.  

Scientists discovered new evidence to support their theories.  

Scientists used observations and mathematical data to solve problems in new ways.  

<u>Explanation:</u>

At first the Ptolemaic model suggested that the earth was the centre of the solar system around which the sun, moon and other planets revolved. This Copernican revolutionised by finding Sun in the centre of the solar system around which the earth and the other planets revolved. After his discovery the earth was just given a status of yet another planet.

The scientists who were researching on this made few advancements using their scientific knowledge and hence found new evidences to support their theory. Scientists then researched conducted experiments using mathematical calculations to solve their problems.
