Answer:
third and fourth trophic levels
Explanation:
The higher biodiversity in an ecosystem means that there is a greater variety of genes and species in that ecosystem. A great variety of genes and species means that the ecosystem is better able to carry out natural processes in the face of external stress. Thus, the ecosystem is more sustainable.
The right answer for the question that is being asked and shown above is that: "C. People can be tested for mutations on these genes." The statement that is true about BRCA1 and BRCA2 genes is that p<span>eople can be tested for mutations on these genes.</span>
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:
Nucleus
Explanation:
The Nucleus acts as the "brain" of the cell, working to store and replicate DNA.
