Describe how the SARS-CoV-2 virus affects your cells.

gogolik [260]

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.

Kepler's second law using Mercury , which has an orbital period of about 0.24 and a semimajor axis of about 0.387 . Explain your

krok68 [10]

As the semimajor axis of a planet increase, the orbital period will decrease and the speed of the planet will decrease.

<h3>What is Kepler's second law?</h3>

Kepler's second law of planetary motion describes the speed of a planet traveling in an elliptical orbit around the Sun.

This law exaplains the speed of planets around the sun, the speed of the planet increases as it nears the sun and decreases as it recedes from the sun.

From the findings, the astronomical unit of the Mercury is 0.387 and the orbital period is 0.24 year.

$T \propto a^{3/2}$

$T = ka^{3/2}\\\\k = \frac{T}{a^{3/2}}$

From the equation above, as the semimajor axis of a planet increase, the orbital period will decrease and the speed of the planet will decrease.
