which statement best describes one positive and one negative way that society was impacted by the use of DDT?


A. Society was positively impacted by increased insect control in crops, but it was negatively impacted by harmful chemicals.

B. Society was positively impacted by insect resistance, but it was negatively impacted by harmful chemicals.

C. Society was positively impacted by increased insect control in crops, but it was negatively impacted by malaria and typhus.

D. Society was positively impacted by insect resistance, but it was negatively impacted by malaria and typhus.

Answers

Answer: The answer is A

Explanation:

Society was positively impacted by increased insect control in crops, but it was negatively impacted by harmful chemicals. Hence option A is correct.

What is DDT?

DDT is defined as the 1940s saw the development of the first synthetic modern pesticide. It aided in the prevention of illnesses like typhus and malaria. Researchers classify DDT as an endocrine-disrupting chemical, or an EDC, because there is evidence that it alters and disrupts hormones crucial for healthy health, including reproductive health, as well as neurological and immunological processes.

Even while scientists began to raise concerns about such risks in the middle of the 1940s, it wasn't until the publication of Rachel Carson's book Silent Spring in 1962 that the use of the chemical became the subject of broad public concern. DDT, often known as dichlorodiphenyltrichloroethane, is a pesticide used in farming. DDT usage was outlawed in the US in 1972. DDT is still used in several non-American nations to keep mosquitoes that cause malaria at bay.

Thus, society was positively impacted by increased insect control in crops, but it was negatively impacted by harmful chemicals. Hence option A is correct.

How are DNA mutations related to changes in proteins and traits?

Answers

Answer:

Mutations in the gene result in an alteration of the protein so that epithelial cells are defective in transporting these ions out of cells. Because less salt is secreted from the cells lining these airways and ducts, there is less water "drawn out" of the cells.

:-))

Answer:

By changing a gene's instructions for making a protein, a mutation can cause the protein to malfunction or to be missing entirely. When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition.

7. What codes for development and growth?
a. Heterotrophs
b. Genetic Material
Cellular Respiration
d. Multicellular Nuclei

Answers

It’s c because I took the test

Cellular Respiration codes for development and growth. The correct option is C.

Thus, DNA (deoxyribonucleic acid), which makes up the majority of genetic material, contains the instructions for an organism's growth and development. The instructions or genetic code that determines an organism's traits, capabilities, and attributes are found in its DNA.

The genetic code is used to produce proteins and other compounds required for growth and development through the process of gene expression. Through reproduction, this genetic information is transferred from parent to child, maintaining a trait's continuity over generations.

Cellular respiration (c) is the mechanism by which cells produce energy by dissolving organic molecules, whereas heterotrophs (a) are organisms that receive their energy by eating other organisms.

Thus, Cellular Respiration codes for development and growth. The correct option is C.

If an individual has the genotype AaBb, what are the combinations of alleles that would be
found in their gametes?

Answers

Answer:

There are four possible combinations of gametes for the AaBb parent. Half of the gametes get a dominant A and a dominant B allele; the other half of the gametes get a recessive a and a recessive b allele. Both parents produce 25% each of AB, Ab, aB, and ab.

I hope this helped

The combinations in the alleles that are carrying out the genotype of AaBb then at that stage the alleles combinations that will be present in their gametes will be AB, ab, Ab and aB.

What is a genotype ?

It is defined as the genetic expression of an individual. It defines the traits  and the characters that are present in the individual in order to decide the phenotype of an individual.

In the genotype of AaBb, it is the combination as the both of the genes copies are present and in this case due to very obvious reasons it is the capital one that is going to express itself. The other genes are definitely present but with a effect that will be covered out by the dominant one.

The 4 combinations that will be present are  AB, ab, Ab and aB where the 1st one where the both of the dominant ones will be present will be carrying the dominant genes, ab in this the recessive ones will be present and in others ones, one dominant and one recessive is present.
