The answer is <span>insect and pest populations decreased.
</span>
DDT (dichlorodiphenyltrichloroethane) was used as an insecticide which is a substance used to kill insects. That resulted in decrease in insect and pest populations. It is a persistent and non-degradable insecticide, but as well organic pollutant readily accumulated to soils and consequently affects organisms.

Answer:
Please find the explanation below
Explanation:
Deoxyribosenucleic acid, commonly called DNA is the stored form of genetic material in living cells. It contains the information needed by an organism to survive. A segment of the DNA that encodes the necessary information needed to produce a particular protein that determines a trait is called GENE.
The DNA consists of long polynucleotide chains, hence, due to Its length, it cannot git into the cell. The cell then devises a means by wrapping the long strands of DNA around certain proteins called HISTONES. This initially forms a NUCLEOSOME structure, then continuous wrapping around histones and condensation forms the visible CHROMOSOME structure.
Now, the CHROMOSOME contains the DNA molecule, which contains protein-coding segments called GENES. The information contained on the gene is used to produce a protein that is responsible for a particular TRAIT in the organism.
Answer:
1)The criteria pollutants are carbon monoxide, lead, nitrogen dioxide, ozone, particulate matter, and sulfur dioxide. Criteria pollutants are the only air pollutants with national air quality standards that define allowable concentrations of these substances in ambient air.
2)Examples of a secondary pollutant include ozone, which is formed when hydrocarbons (HC) and nitrogen oxides (NOx) combine in the presence of sunlight; NO2, which is formed as NO combines with oxygen in the air; and acid rain, which is formed when sulfur dioxide or nitrogen oxides react with water.
3)By bringing national attention to water pollution issues, the Cuyahoga River fire was one of the events that led to the creation of the federal Environmental Protection Agency and the Ohio Environmental Protection Agency.
4)sry idk this one ☝️
5)On Days when High Particle Levels are Expected, Take these Extra Steps to Reduce Pollution:
Reduce the number of trips you take in your car.
Reduce or eliminate fireplace and wood stove use.
Avoid burning leaves, trash, and other materials.
Avoid using gas-powered lawn and garden equipment.

mark me as brainiest pls :)
<>"A further increase in the size of a cell could result in a surface area too small for adequate exchange of materials. Google: A large surface to volume ratio means that a small amount of living matter has a large surface through which nutrients, oxygen and wastes can diffuse."<>
