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

There are many different types of cells with many different types of cellular structures and functions. Which of these structures is found in all types of eukaryotic cells?
A. chloroplast
B. cell wall
C. nucleus
D. centrioles
Answer:
nucleus
Explanation:
chloroplasts and cell walls are only found in plant (and fungi) cells, while centrioles are only in animal cells.
The structure that is found in all types of eukaryotic cells is the nucleus. The correct option is C.
What are eukaryotic cells?Eukaryotic cells are those cells that contain true cell organelle. These cells are present in the higher organism, and they perform complex functions like replication, mitosis, etc.
There are two types of cells. They are prokaryotic and eukaryotic cells. Prokaryotic cells are those that do not contain an organelle and a nucleus. They are present in smaller organisms.
The nucleus is the brain of cells. It controls all functions of cells, and it contains the genetic material of the organisms. In prokaryotic cells, the nucleus is absent and in eukaryotic cells, the nucleus is present. That is the difference between them.
Thus, the correct option is C. nucleus.

How does DNA copy itself
Explanation:
DNA unwraps itself before cell division. It helps that each side of the double helix is in opposite direction of the other. Then the DNA polymerase travels around each strand and binds the complementary nucleotides (DNA's building blocks). The process is called DNA replication.

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.
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.

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