Answer:
Basically, most antibiotic drugs are not effective in controlling bacterial growth. The potency of any antibiotic drugs is a measure of the magnitude of diameter of the bacterial growth . <u>This is because the diameter is the measurement of the bacterial growth around the antibiotic drugs used to control it multiplication, and therefore a measure of how effective it can controls the population</u> Thus a small diameter around the antibiotic agent is a proof that it suppressed the growth effectively and can effectively be used to control the bacteria, While a large diameter is an indication of low effectiveness of the drug.
Based on this analogy, penicillin with wide usage for control of bacteria growth with diameter of 3mm, is the most effective antibiotic drugs.However, Erythromycin which is also widely used control growth with diameter of 5mm or 6mm depending on type of bacterial.
Therefore, the least 3mm diameter presented by penicillin is an indication that , antibiotic drugs are not effective enough, and further research need to be done to control growth of bacteria and therefore its pathogenic effects.
Explanation:
The answer is E. Arctic temperatures are increasing; the arctic fox is hibernating for longer periods of time.
Since the temperatures are increasing, Winter becomes longer, giving organisms a longer time to hibernate. Hope I helped :)
Stem cells because they are compatible of dividing and renewing themselves after long periods
I think it's B an injury to the central nervous system.
They study the human body
