A particle can infect humans and make them sick. It attaches to a host cell and injects its RNA, which the host uses to make pro
trasher [3.6K]

Answer:

The most appropriate answer would be A. The particle is a virus because it does not use energy and cannot reproduce by itself.  

Virus is defined as a small infectious agent that carry its own genetic material (DNA or RNA) but divides only in the living cells of other organisms (bacteria, human, animals, plants etc).

They are acellular in nature and thus are not able to reproduce on their own. They use the metabolism and machinery of the host cell in order to produce and assemble multiple copies of themselves in a cell.

They attach to the specific binding site of their target cells and inject their genetic material into the cell. The host cell's machinery is then used to replicate, transcribe and translate viral genetic material.

The viral genome produced are assembled in the protein cascade. They are then released by causing bursting of the infected cell.

What analogy can you create that compares to the structure of all four major macromolecules?
skad [1K]
Basically, macro molecules  fall into four classes;
The lipids
The carbohydrates
The proteins
The nucleic acids
 The fact that their role revolve around energy production by carbohydrates, energy storage and insulation by lipids, storage of genetic material by nucleic acids and structural support by proteins means this can be equated to the executive arm of the government that deals in provision of social amenity, protection,  creation of job opportunities and sustaining a country's culture.

What is unique about spring C? Question 19 options: It has the same temperature as the human body. It is the most common spring
Marizza181 [45]

Answer:

Option (3)

Explanation:

Springs (hot springs) and geysers are formed when the water from the interior of the earth are ejected into the earth's surface. In simple words, these are formed in the region where the groundwater and the ground surface intersects with each other.

The water obtained from springs can be cold or hot. Those that produce hot water are termed as hot-spring. These hot springs and geysers indicates the occurrence of volcanic activity. This water becomes hot due to the interaction with the magma at certain depths below the ground surface.

The geysers are also a type of hot-springs which produces hot water.

Thus, the correct answer is an option (3).
