Answer: False
Explanation:
Just because an environmental agent is not harmful does not mean that it is beneficial therefore not all non-harmful environmental agents that a pregnant woman ingests aid in the development of the fetus.
This is where the Placenta comes in. It filters out the agents and nutrients that are not needed and passes only the relevant ones to the fetus thereby ensuring that not all non-harmful agents pass through.

The question is incomplete as it does not have the options which are:
A. bioremediation
B. mutualism
C. quorum sensing
D. quorum settling
E. mass-settling
Answer:
C. quorum sensing
Explanation:
Quorum sensing is the gene regulation mechanism used by the bacteria to communicate with the other bacteria. The quorum sensing process depends on the number of bacterial cells or the density of the cells.
When the bacterial number increase in number then the bacterial cells send the signal to the nearby cells and and regulates the expression of the gene. In the given question, the same chemical signal process depends on the density of the cell and thus quorum sensing is correct.
The most abundant in the atmosphere are Nitrogen, Oxygen, Argon, and Carbon Dioxide. All of these combined take up about 99.9% of the Earths atmosphere
Hope this helped!! :D
Your answer is B.) Heterozygous, since the prefix 'hetero' usually means separate or different. Hope this helps.
