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.
