what is the relationship between exposing to a virus and developing immunity to it? cite evidence from the text to support your response
Answer:
Exposure to a virus is closely related to the development of immunity, since the immune system is responsible for creating antibodies in response to the presence of potentially harmful biological agents, such as these viruses.
Explanation:
Viruses are biological agents that can produce diseases when they enter the body of a living being. In response to contact with a virus, the immune system synthesizes specific antibodies to combat the foreign biological agent.
Antibody immunity can be of two types. It is fast when it is mediated by immunoglobulins M (IgM), which attack the virus anywhere, while the late and prolonged response is due to the development of immunoglobulins G (IgG).
An example of immunity to a virus occurs with the exhibition to the virus of the Dengue, that creates permanent immunity to the viral serotype to which an individual is exposed.
The acquired immunity, mediated by antibodies, is the base for the development of vaccines.

Antibiotic resistance can evolve in bacteria via the following mechanisms
Select one:
A. Transformation, conjugation, and transduction.
B. Transformation, reformation, and conjugation
1
O C. Reformation, fission, and conjugation.
O D. Transformation, fusion, and conjugation.
Three mechanisms of horizontal gene transfer that can lead to the evolution of antibiotic resistance in bacteria are transformation, conjugation, and transduction. Hence option A is correct.
What is transformation?Transformation is the process by which bacteria take up DNA from their surroundings and incorporate it into their genome.
Conjugation involves the transfer of DNA from one bacterium to another through a pilus, a thin tube-like structure.
Transduction occurs when bacteria acquire DNA from a virus that has infected them.
These mechanisms of horizontal gene transfer are significant because they allow bacteria to quickly adapt to new environments and acquire antibiotic resistance genes that can help them survive in the presence of antibiotics.
This can lead to the development of superbugs that are resistant to multiple antibiotics and can cause serious infections that are difficult to treat. It is important to use antibiotics judiciously and to develop new antibiotics and alternative treatments to combat antibiotic resistance.
Hence option A is correct.

If C added after the equilibrium is reached,which direction forward or reverse reaction will it go
Equilibrium is when the rate of the forward reaction equals the rate of the reverse reaction. All reactant and product concentrations are constant at equilibrium.
The forward reaction is the one in which reactants are transformed into products (A + B → C + D), whereas the reverse reaction is the one in which products are transformed back into reactants (C + D → A + B).
Before the products can materialise, the forward reaction must begin. The rate of the reverse reaction, therefore, begins at zero. The pace of the reverse reaction, however, gradually picks up speed while the rate of the forward reaction decreases as C and D emerge and their concentration increases. The concentration of A and B is falling, which is why things are moving more slowly. This occurs because the reaction needs to eat up A and B in order to produce C and D.

hope this helps:)
A biologist pollinates a true-breeding yellow flower with pollen from a true-breeding red flower of the same species. All of the F, offspring are yellow. The question can be Is flower color polygenic?
What is True breeding plant?A true breeding is a kind of breeding wherein the parents would produce offspring that would carry the same phenotype. This means that the parents are homozygous for every trait.
An example of true breeding is that of the Aberdeen Angus cattle. The cattle have been black for many generations, which is an indication that such trait passed on from many generations remains pure.
With plants, true breeding occurs when plants produce only offspring of the same variety when they self-pollinate. For instance, a plant that has blue flowers will produce only seeds that will grow into plants that have blue flowers.
Therefore, A biologist pollinates a true-breeding yellow flower with pollen from a true-breeding red flower of the same species. All of the F, offspring are yellow. The question can be Is flower color polygenic?

If a cell suddenly stopped producing transfer RNA, which of the following processes would be immediately affected?
A) MUTATION
B) REPLACATION
C) TRANSCRIPTION
D)TRANSLATION
Answer:
D
Explanation:
If a cell suddenly stopped producing transfer RNA, the process that would be immediately affected is translation. The correct option is D.
What is translation?The translation is the second step of the process of protein synthesis. In translation, the RNA give instruction to the ribosomes, and they produce protein.
The first step in protein synthesis is transcription, in which the DNA gives its template to produce RNA. The RNA then in translation produces protein. The translation is divided into three steps. They are initiation, elongation, and termination.
Initiation starts the process and elongation runs the process. The termination gives the stop codons to stop the process. The codons are the codes of genetic codes.
Thus, the correct option is D. translation.

How can the group be sure it is calcite?
A)
use the acid test
B)

C)
see if it is attracted to a magnet
D
compare the color to other minerals
Answer:
The correct answer is - a) use the acid test.
Explanation:
In this chart, there are many minerals that share different properties with one another such as hardness, color, and luster of the minerals so on the basis of physical properties the group of students can not be sure if the given mineral is calcite or not.
To be sure if the given mineral is calcite the group of students must test the acid test which is specific for the calcite and if the test produces bubbles it is confirmed that the given mineral among these minerals is calcite.

In an analysis of the nucleotide composition of DNA, which of the following proportions will be found?
to. A + C = G + T
b. G + C = T + A
c. C = C
d. A = G and C = T
Answer:
With respect to the composition of DNA, in an analysis it can be found that the proportions of nucleotides are A + C = G + T (option a).
Explanation:
The proportion of nucleotides in a DNA molecule can be established according to the sequence of these nucleotides on both complementary strands, since the purinic bases of one strand are complemented by the pyrimidinic bases of another:
Adenine is complemented with Thymine A=TGuanine is complemented with Cytosine G=CFrom this we can deduce that in a DNA molecule with two chains there will be the same amount of adenine and thymine, as well as the same number of guanine with respect to cytosine, so:
A + C = G + T
An example of this would be a known DNA molecule (hypothetical), with 5 molecules of Adenine and 7 molecules of Guanine. In this case there are 5 Thymines, complementary with Adenine, and 7 Cytosines like Guanine:
A + C = G + T
5 + 7 = 7 + 5
