The answer is 6 per m2.
A population density is the number of animals per 1 m2.
So, this problem can be solved by using a proportion:
If 60 raccoons live in 10 m2, how many raccons will live in the 1 m2.
60 raccoons : 10 m2 = x raccoons : 1 m2
60 raccoons : 10 = x raccoons
x raccoons = 6 raccoons
Thus, the population density is 6 raccoons per m2.

Answer:
According to what is observed in point A of the graph, referring to the population of beetles, there is no competition for resources.
Explanation:
The graph shows that a controlled population of beetles, where other individuals do not enter or leave, experiences <u>progressive growth over time</u>. This is because the population has sufficient resources to guarantee their development, the birth rate exceeds that of mortality and there is no competition for these resources.
The adequate amount of resources allows that, at point A, the carrying capacity has not been reached, a consequence of no competition among members of the same species, which ensures that the net population growth rate is maintained or even increase.

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.
