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.

Brainliest answer for correct. Thanks
makvit [3.9K]

Answer:

The correct answer is option B, Encourage people in the neighborhood to use more disposable products.

Explanation:

The best way to reduce the waste is to stop its negative impact at the source of generation. In a neighbor hood,  all the house can be considered as a source of waste generation. Thus if people are encouraged to use disposable product, it would be very easy to just collect and dump the waste without segregation. This will save time, money and effort.

Alexandra [31]

Answer:

The function of carotenoids in plant is the dissipation of excess light energy.

Explanation:

Carotenoids are a group of chemicals that are found in food, the chemicals possess antioxidant properties, which help the cell to get rid of radical species. Carotenoids are also presents in plants.  In plants, carotenoids help the plants to absorb energy from sunlight to carry out photosynthesis. They also protect chlorophyll in plants from been damaged by the sun.

Answer:

A. Total Vit D intake = 1150000212 IU

B. Yes he met his RDA and does not need any supplements

C. 191666702%

Explanation:

I μg = 40 IU

1 oz = 28.35 g

I g = 1000000 μg

A. Low-fat Yoplait yogurt-2 μg = 2 * 40 IU = 80 IU

Cheerios cereal-1 μg = 40 1U

Coffee with milk-07μg = 0.7 * 40 = 28 IU

Turkey sandwich on whole-wheat bread with large garden salad-0.4 g = 0.4 * 1000000 * 40 IU = 16000000 IU Grilledd pork chop. 8 oz = 28.35 * 1000000 * 40 = 1134000000 IU

mashed potato and a side of gnled mixed vegetables-1.6 μg = 1.6 * 40 = 64 IU

Total vitamin D intake = 1150000212 IU of Vit D.

B. Since his RDA is 600 IU, he met his RDA and does not need any supplements of Vit D.

C. Percentage of his RDA Vit D intake = (1150000212/600) * 100% = 191666702 %
