Answer:
The correct answer would be the virus envelope.
Viral envelope is a protective covering present around the capsid proteins in some viruses.
It is usually derived from the cell membrane of the host and thus it is composed of lipid and viral proteins.
It provides stability to the viral particle, helps in protecting the viral genome, and aids in the fusion of the virus with the membrane of the host.
Examples of viruses in which envelope is present: herpesviruses, poxviruses, flavivirus, hepatitis D et cetera.
Examples of viruses in which envelope is absent: adenoviridae
, papillomaviridae
, picornaviridae
, caliciviridae et cetera.
Hurricanes form when warm, moist air rises over the water. Cooler air replaces the rising air. Mr. Gaines's class identified that the pressure in the center of the hurricane is decreasing which indicates the storm is getting stronger as the wind increases, i.e., option 3.
<h3>What is a Hurricane?</h3>
A hurricane is a powerful cyclone that is tropical and forms in the Atlantic or Northeast Pacific Oceans.
Surface atmospheric pressure is fairly low in the center of a hurricane. An eye forms in the center of the storm system as it rotates faster and faster. With very low air pressure, it is very calm and clear in the eye.
Thus, the correct option is 3.
