What are biotic or abiotic components?

Biotic components are living organisms while abiotic components are nonliving organisms. All biotic components are living components of ecosystem. Bacteria and birds, animals  are living components.

Abiotic components are non living components. sunlight, water and temperature are the non living components. Biotic factors are producers, herbivores and omnivores.

Abiotic components are physical and chemical components that act on the living components. In chicken cell the yolk which is living cells.

Biotic components also include the waste from living things and dead organisms. Earth have many biotic components. The surface of Mars has no biotic components.

Therefore, Chicken egg is biotic.

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.

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.

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.
