The explanation regarding the advantage of reproduction that represents the graph should be described below.
Advantages of reproduction:
Here the graph represents the bacteria population that should be raised as the time passes. At the time of 1st hour, the bacteria population should be 50 per ml.
In the second hour, the population should be doubled. In the third hour it should be 200 per ml and in 3 and half hours, the population should be 300 per ml. So here we can see that the population should be doubled with every hour.
Answer:
the answer is A.groups of biomesmake up a community, andand groups of populations make up a biome.

Explanation:
<em>Entamoeba histolytica </em>is the causative agent of amebiasis (amebic dysentery). The pathogen enters the human body through consumption of contaminated water or food and enters the small and large intestines. <em>E. histolytica</em> targets the epithelium of large intestine and creates ulcers in it. <em>E. histolytica </em>enter the mucosa and submucosa of the intestine through these ulcers and leads to severe dysentery, that is amoebic dysentery.
