Answer:
SARS- CoV- 2 is a virus that infects human by the oral-respiratory way in which the virus enters the body and these viruses have spikes on their surface made of spike proteins that allow these viruses to bind with the infected cell.
The infected cells have ACE2 receptor that is protein present on the surface of the human cells. Binding allows the structural change in the virus to fuse and enter in the cell where viruses reproduce them selves with the cell with cell system.
Since chemical weathering is the reaction of rocks with other chemicals, the answer should be answer D!

The filtrate is first refined and concentrated by the processes of <u>reabsorption and secretion</u>, which form the urine that leaves the body.
<h3>Process of filtration in kidney:</h3>
The glomerulus filters your blood, and the tubule restores necessary substances to your blood while removing waste. The glomerulus is nestled within a region of the kidney called the Bowman's Capsule. This is where filtration occurs. The high pressure causes some substances to pass through the capillary walls when blood is forced through the tiny capillaries. The walls serve as a filter or sieve. This is how the function of the nephron. A glomerulus filters your blood, while a tubule restores necessary substances to your circulation while removing extra waste. Each nephron has both of these functions.
