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.
1. Hind limbs tend to be sturdier, longer, stronger.
<span>2. The hind limbs are more firmly attached to the spine than are the forelimbs.</span>
Answer:
1. The codons on the mRNA transcript contain an extra base which causes the amino
acid chain to not make the desired protein.

Then error will make it not to produce the required output

<span>Early pre-cambrian period the atmosphere consisted only of nitrogen and carbon dioxide without oxygen.
<span>A
Prokaryotic cell does not contain a nucleus. It only contains one
chromosome and is a single-celled organism. It was the only form of life
on earth for millions of years. Examples of a Prokaryotic cell are the
different types of bacteria present today.
</span><span>Autotrophs
obtain energy by the process of photosynthesis. Any living organism
need energy to survive and autotrophs are no different. Two types of
autotrophs are present and they are Photoautotrophs and Chemoautotrophs.
The Photoautotrophs rely on the energy produced during the process of
photosynthesis and the Chemoautotrophs get their energy from most of the
inorganic substances. Phtoautotrophs actually get their energy from the
sunlight and then convert it into reusable form. In case of
Chemoautotrophs ammonia is an important source of energy for them.</span></span>
Three phases of matter are solid, liquid and gas. They are <span>all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. Gas and liquid flow easily, but solids do not flow. Gas and liquids assume the shape of the container they are held in, but solids retain a fixed volume and shape. </span>
