D = m/v
Given:
D: .835 g/cm3
V: 34 cm3
M: ?
M= Dxv
M= .835 g/cm3 x 34 cm3
M= 28.39 g
ANSWER: POPULATION ECOLOGY
EXPLANATION:
The scientific field that deals with populations (i.e all individuals of a single species inhabiting a community) and how they interact with their extrinsic environment, is referred to as POPULATION ECOLOGY.
Thus, it's categorized under population ecology, because the research depicts how the number of individuals (beetles) in a population changes in time and the gross impact on their number decrease and loss of all the individuals (extinction) over a period of time.
Explanation:
The influence from radioactivity is inversely proportional to the number of chromosomes , since , humans have more DNA , chromosomes than the insects , and therefore , due to less chromosomes in insects , they are more resistant towards radioactivity .
As the target of the radiation is the DNA .
Hence , It is clear that insect due to lesser DNA are less prone to Radiations .
The answer to this question would be: <span>producing large quantities of proteins for secretion.

A cell with many rough endoplasmic reticulum has a high protein synthesis capability. This will make the cell able to produce many proteins like enzyme. One example of this type of cell will be pancreas cells. This cell will need many enzymes to digest food that you eat so it will need many ER to produce it.
