Answer:
If actin is unable to bind to the ATP molecule, it will not be able to assemble into its two dominant forms.
Explanation:
As shown in the question above, the two predominant forms of actin are ATP-G-actin and ADP-F actin. As we can see, the formation of these two molecules involves the presence of an ATP molecule, in which case, the concentration of actin inside an organism depends totally on the capacity of the actin to be able to bind to an ATP molecule. If there is a mutation that prevents this binding from occurring, actin will not be able to form its two dominant forms, which will harm the presence of actin in the body.

A penicillin reaction is a life-threatening event. In those who are allergic to penicillin, the drug acts as a __________ that binds to blood proteins, causing a strong immune response.
Answer:
A penicillin reaction is a life-threatening event. In those who are allergic to penicillin, the drug acts as a hapten that binds to blood proteins, causing a strong immune response.
Explanation:
Low molecular weight chemicals can bind to antibodies, but cannot activate B lymphocytes by themselves (they are not immunogenic). To generate specific antibodies to these small chemicals, immunologists typically bind them to macromolecules prior to immunization. In these cases, the chemical is called a hapten. Penicillin G is a typical hapten that tends to covalently bind to lysine residues both in solution and in protein-bound cells. Penicillin is a drug that behaves as a hapten, since the beta-lactam ring under physiological conditions opens and reacts with the lysine residues of proteins, forming a complex that is the main antigenic determinant of penicillin and other beta-lactams and is capable of to stimulate responses mediated by antibodies or by T cells.

what are the difference between DNA and RNA
Answer:
There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.
The statement that there must be a preexisting cell in order for a new cell to form is known as cell
Answer:
cells duplicate so when there is no cell it cant make any
Explanation:
The statement that there must be a preexisting cell in order for a new cell to form is known as cell theory.
What is cell theory?The scientific idea that cells make up living organisms, that they are the fundamental structural and organizational unit of all species.
They all originate from previously existing cells is known as cell theory. It was first proposed in the middle of the nineteenth century.
Because cells are the building blocks of all life, cell theory is essential for our understanding of biology.
We can have single-celled organisms like yeasts and bacteria. All living things grow and develop on the basis of cell division, or the division of a cell from one to two to four.
A vital process for life is mitosis. A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes.
Thus, the statement "cell arises from pre-existing cells" comes from cell theory.

What molecules transfer heredity from parents to offspring?
Answer:
a molecule called DNA (deoxyribonucleic acid) is passed from adult organisms to their offspring during reproduction.
DNA molecules transfer heredity from parents to offspring.
What is DNA?DNA or deoxyribonucleic acid exists considered the genetic material that transmits genes from Parents to offspring. DNA exists found almost inside every cell. The molecular structure of DNA existed discovered by James Watson and Francis Crick in the year 1953. They obtained Nobel Prize for it in the year 1962.
DNA exists created up of molecules called nucleotides. Each nucleotide contains three elements: a phosphate group, which stands for one phosphorus atom bonded to four oxygen atoms; a sugar molecule; and a nitrogen base.

Note that arteries have a thicker middle layer of tissue than veins. Why is this important and how does it affect the structure of the artery as compared to the vein?
Answer:
The correct answer is - To withstand the high pressure of the outflow of blood from the Heart.
Explanation:
The heart pumps blood to different body parts at high pressure so that it can easily reach all the parts of the body quickly. To able to hold the pressure of the blood pumped at high-pressure arteries need thick walls.
This pressure can be experienced as pulse and which required the walls of arteries and the middle layer or the tunica media to make it much thicker in arteries than in veins. In veins pressure caused by blood is very low pressure that allows them to be thin walls.

The protein calcineurin binds to the protein calmodulin with an association rate of 8.9 × 103 M-1s-1 and an overall dissociation constant, Kd, of 10 nM. The dissociation rate kd is:_____. Please explain step by step.
A. 8.9 × 10^3 M-1s-1
B. 8.9 × 10^2 s-1
C. 1.1 × 10-10 s-1
D. 8.9 × 10-5 s-1
Answer:
D
Explanation:
From the information given:
Association rate [tex]K_a[/tex] = [tex]8.9 \times 10^3 M^{-1}s^{-1}[/tex]
dissociation constant [tex]K_D[/tex] = 10 nM
dissociation rate [tex]K_d[/tex] = ???
Using the following relation from equilibrium dissociation constant to determine the dissociation rate, we have:
[tex]K_D =\dfrac{ K_d}{K_a}[/tex]
[tex]K_d = K_D \times K_a[/tex]
[tex]K_d =(10*10^{-9} \ M) \times (8.9*10^3 \ M^{-1}{s^{-1})[/tex]
[tex]\mathbf{K_d =8.9*10^{-5} \ {s^{-1}}}[/tex]

In a diploid cell, a FISH probe should produce ____________ signals in metaphase FISH and ____________ signals in interphase FISH.
Answer: Four, two
Explanation:
FISH (fluorescence in situ hybridization) is a technique for chromosome mapping with probes that emit fluorescence and allow the visualization, distinction and study of chromosomes of nuclei in metaphase or inferophase. In this way, any type of anomaly such as inversions, aneuploidies, duplications or microdeletions can be seen. To do this, a non-specific DNA staining is performed with DAPI (a fluorophore that marks the nucleus where DNA is present) and the fluorescence will be seen under the microscope.
When cells are in metaphase, their chromosomes are condensed in preparation for cell division. To stop them in metaphase, colchicine is used which is a microtubule depolymerizing agent responsible for separating the sister chromatids of a chromosome, thus preventing the progression of cell division and arresting the cell cycle in metaphase. Here we will see translocations, microdeletions or duplications.
Interphase FISH is used to see decondensed chromatin, which allows higher resolution in detecting small abnormalities. It is mainly used for the detection of aneuploidies or large deletions, duplications or translocations when samples are difficult to grow or are scarce, as in the case of fetal or tumor cells. It is not possible to distinguish between a normal karyotype and a karyotype showing a balanced translocation. In addition, it can be used in the analysis of solid tumors, which divide very infrequently.
During metaphase, the chromosomes are duplicated so there would be two sets of chromosomes (a total of four chromosomes). Then, there would be four signals for each probe. During interphase, the chromosomes are not dupicated. Since it is a diploid organisms, there would be two chromosomes and this will represen two signals for probe.

It is observed that constipation is more common among people in the western countries who eat more meat and processed food than us. What could be the reason for this? What should be changed in their diet?
I already know this answer, just checking, it's cuz of roughage
Answer:
yes your answer is correct
Explanation:
Constipation happens when the colon absorbs too much water, this can occur if the muscles in the colon are contracting slowly or poorly, causing the stool to move too slowly and lose more water. As meat need much water to digest, so they leads to problem of constipation. Hence, they should eat sufficient amount of water to cure constipation.
Constipation is common among people in western countries who eat more meat and processed food because there is no enough roughage in their bodies which prevents constipation .Fruits and vegetables like like corn etc contains lot of roughage.
