Why is the changeable nature of models considered a limitation?

2 answers:

The changeable nature of models is considered a limitation because when the model alters, the answers that were achieved from the model may also transform. What this means is that outcomes that’s been extracted from changeable models can be true at a certain moment, place or situation, but the conclusions may not be objectively true.

The changeable nature of models is considered a limitation because this makes it impossible to use the same model in all situations. Usually, models operate within a set of specific conditions. As long as these conditions remain the same, the model can be trusted. However, if the conditions change, the model might not be as useful anymore, and a new model would have to be developed.

Describe the effects of the various antibiotic drugs you used. Were they all equally effective at controlling bacterial growth?

Kipish [7]

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 . 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 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.

Why would a mutation that involves a centromere have a greater impact than a mutation that occurs elsewhere on a chromosome?

RideAnS [48]

If mutation is associated with the centromere region, the direct impact would be on the segregating mechanism during cell division process.
