Viruses and bacteria are both microscopic and can both cause disease. viruses differ from bacteria in that all viruses *
a. have cell walls.
b. can be destroyed by antibiotics.
c. need a living host cell to reproduce.

b. can be destroyed by antibiotics.

Explanation:

Antibiotics can act in two different ways:

As a bactericide, completely destroying bacteria, or as a bacteriostatic, inhibiting their replication.

Antibiotics are ineffective against viruses because they do not have their own metabolism. If the antibiotic is given to a patient with a viral infection, it can cause side effects or even antibiotic resistance problems.

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
