Answer:
The correct answer is - Ping pong Mechanism.
Explanation:
The ping pong mechanism of the enzyme is a non-sequential mechanism of two-substrate enzymatic reaction in which product is produced after the binding with the first substrate.
After the produced form due to the binding of the enzyme to the first substrate, it changes into a temporary form that binds with the second substrate and completes the reaction.
Thus, The correct answer is - Ping pong Mechanism.

1. One positive use of viruses is their function as a. infectious particles. c. cloning vectors. b. pandemic initiators. d. marine predators.
Answer: The correct option is C.
Cloning vectors.
Explanation:
Viruses are use as cloning vectors because they can give the new gene or birth the new gene by infecting the cell. They are so modified and orogrammed in such a way that they cannot cause disease when it is used in humans. Cloning vector is a DNA fragment gotten from viruses or bacteria plasmid which is maintained and used for cloning purposes.

True breeding plant round seeds (DD) were bred with true breeding smooth
seeds(dd) to produce F1 offspring. F1 offspring were then bred with other F1
offspring. What is the genotypic ratio of the resulting F2 offspring? What is the
phenotypic ratio of the resulting F2 offspring?
Answer:
Genotypic ratio F2 = 1:2:1
Phenotypic ratio F2 = 3:1
Explanation:
In this case, parental genotypes can produce only one type of gamete, i.e., one parent can produce only D gametes, while the other parent can produce only d gametes. Therefore, all F1 generation will be heterozygous (Aa). An F1 hybrid is the first filial generation of offspring obtained from crossing between different parent types. The F1 will produce two gametes (A; a) in a ratio 1:1, thereby the F2 obtained by crossing F1 offspring will have a phenotypic ratio of 3:1 (3 D_; 1 dd) and a genotypic ratio of 1:2:1 (1 AA; 2 Aa; 1 aa).
Dihydromyricetin (DHM), a chemical found in the moyeam plant of Asia, has shown the ability to treat certain
cancers.
Which of the following answer choices best describes a possible mechanism of action for this cancer drug?
Choose 1 answer:
А
DHM decreases apoptosis in cancer cells.
DHM decreases apoptosis in normal cells.
DHM promotes apoptosis in cancer cells.
D
DHM promotes apoptosis in normal cells.
Answer:
(C) DHM promotes apoptosis in cancer cells.
Explanation:
Since some cancers are caused by a lack of apoptosis (programmed cell death), DHM treats cancer by forcing apoptosis to occur in cancer cells, stopping their growth and division.
The choice which best describes a possible mechanism of action for this cancer drug is DHM promotes apoptosis in cancer cells. The correct option is C.
What is Dihydromyricetin (DHM)?DHM is a chemical that is present in the plant, Hovenia Dulcis grow in Japan. It is a raisin plant and has several medicinal values. It is used in East Asia as a hangover medicine.
Apoptosis is a process of cell death, so if DHM promotes apoptosis in the cancerous cells, then it will reduce cancer by killing the cancer cells.
Thus, the correct option is C, DHM promotes apoptosis in cancer cells.

The chemical equation of cellular respiration contains information about?
a. the relative amount of products and reactants.
b. the formation of glucose.
c. the intermediate reactions needed to break down glucose.
d. the environment in which cellular respiration occurs.
The chemical equation of cellular respiration comprises information regarding the relative amounts of products and reactants.
• The process, which takes place within the mitochondria of all the organisms is termed cellular respiration. In this process, the simple sugars are dissociated into water and carbon dioxide and release energy in the form of ATP.
• A chemical reaction is a procedure in which one or more components, that is, the reactants get transformed into one or more different components called the products.
• The substances, which start the reaction are called reactants, while the ones that get produced in the reaction are called products.
• The association between the reactants and products in a chemical reaction can be signified with the help of a chemical equation.
Thus, the chemical reaction of cellular respiration comprises information regarding the relative amount of products and reactants.

Do you believe that all of our actions can be attributed to the nervous system? Does your memory of an event trigger your responses? Why or why not?
Answer:
The nervous system is made up of all the nerve cells in your body. It is through the nervous system that we communicate with the outside world and, at the same time, many mechanisms inside our body are controlled. The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain. Metabolic processes are also controlled by the nervous system.

g With respect to their 3' and 5' ends, the two polynucleotide chains of a double-stranded DNA molecule are:
Answer:
They are antiparallel
Explanation:
They are antiparallel because one strand of 3' faces the end of 5' of another strand and 5' end of one strand faces 3' end of another strand. Which indicate that 5 phosphate group faces the end of 3 hydroxyl group and they are of opposite directions to each other because it has opposite polarity with each other .
In DNA and RNA, what “codes for amino acids”?
combinations of nucleotides
combinations of sugars
combinations of proteins
combinations of strands
Answer:
The correct answer is - combinations of nucleotides
Explanation:
The codes for amino acids are encoded in the DNA and RNA in the form of the trinucleotide codons that contain three base sequences which copied in the complementary bases sequence mRNA and then decoded by the ribosome with help of tRNA to produce the original sequence in amino acid sequence or peptide chain.
This nucleotide is also code in the set of 3 base sequences similarly one amino acid is made up of the triplet code.
