Rhinoviruses are transmitted through the air or via contact. We might expect this sort of transmission to require a fairly healthy host (one who gets out and comes into contact with others) and, hence, to select against virulent strains. If we take precautions and try to stay away from people or avoid any contact with people, more hand-washing stations, increased attention to sanitization, and isolation of patients will help to reduce the transmission of the disease and, in the process, may favor the evolution of less virulent strains of the virus.

Virulence and rate of transmission

Explanation:

The rate of transmission is more among less virulent viruses. Natural selection adaption processes balances virulence factor and spread of transmission.

A highly virulent virus may  be highly pathogenic and effect the host seriously rendering him/her immobile and under bed rest. hence the host will not move to many places which might prevent the spread of disease through contacting other persons.

Less virulent viruses on the other hand will have less pathogenic and will not render the patient immobile. So the host will be free to move around everywhere and even if asymptomatic might be a potential carrier of the virus. Hence the rate of transmission will be more in this case.

Answer:

chloroplast: makes food for plant cells, photosynthesis

mitochondria:produces energy the cell needs to carry out its functions; release energy

vacuole: stores food, water, and waste

lysosome: found mainly in animal cells, digests old cell parts

endoplasmic reticulum: carries proteins and other materials from one part of the cell to the other

cytoplasm: gel -like fluid where the organelles are found

nucleolus: makes ribosomes, center of the nucleus

ribosome: makes proteins

cell membrane:controls

Explanation:

I'm pretty sure the answer is D based on the info above,and because its the only one that has the correct information about the cell parts

hope its correct
