Answer: B

Explanation:

G protein-coupled receptors (GPCRs), also known as seven-(pass)-transmembrane domain receptors, 7TM receptors, heptahelical receptors, serpentine receptor, and G protein–linked receptors (GPLR),comprises of a large protein family of receptors that discover molecules outside the cell and initiate internal signal transduction pathways and, eventually, cellular responses. They are called seven-transmembrane receptors because they pass through the cell membrane seven times

Figure 1 represents a segment of DNA. Radiation can damage the nucleotides in a DNA molecule. To repair some types of damage, a
Ne4ueva [31]

Answer:

Explanation:

This question is incomplete. However, what is described in this question is a method of DNA damage repair mechanism. The method described is called base excision repair. Generally, glycosylases play important roles in base excision repair (as they detect and remove these damaged bases).

One thing that can be considered while identifying the bond to be broken is the codon that will be formed after the removal of base. If this codon (a three base sequence) will still produce the same protein as when a normal cytosine was present.

NOTE: During this base excision repair, a glycosylase will detect and remove the damaged cytosine. Once removed, the remaining nucleotide backbone (of the removed cytosine) is also removed and the gap is filled and sealed by other enzymes in this repair mechanism.

​a client with hypovolemia has been prescribed intravenous fluid at 125ml/hr. the iv site to provide hydration has infiltrated.
Levart [38]

The following are the steps the nurse would take to treat the infiltrated site:  

1. Stop the infusion and remove the catheter

2. Elevate the extremity

3. Encourage an active range of motion

4. Apply a cold or warm compress depending on the solution infusing

5. Restart the infusion proximal to the location or in another extremity

Now, in order to address hydration requirements of the client, the nurse will have to begin a novel peripheral intravenous in another extremity or to again start the infusion if intravenous access has been created.

The interaction between two polar molecules would involve ________.
denpristay [2]
The interaction between two polar molecules would involve HYDROGEN BONDS.
Polar molecules are molecules that have both positive and negative charges as a result of the differences in the electronegativity of the atoms that made up the molecule. Polar molecules interact through dipole dipole inter molecular forces and hydrogen bonds.

Which statements could be categorized in the "Asexual" section of the Venn diagram? Check all that apply
EastWind [94]

Answer:

The right answer are : mitosis, diploid cells, and identical DNA.

Explanation:

The answers "two cell divisions" and "gametes" refers to a division by meiosis which is a sexual reproduction.

Asexual reproduction or asexual reproduction is a mode of reproduction, which - as opposed to sexual reproduction - corresponds to the capacity of living organisms to multiply alone, without a partner, without involving the fusion of two gametes of opposite sexes. Asexual reproduction is observed in multicellular (animal and plant) and unicellular organisms. In botany, the term often used for the asexual multiplication of plants is vegetative multiplication. In all cases of asexual reproduction, the result is identical to the mother.
