Why would AZT be a poor candidate to inhibit SARS-CoV2?
Answer:
Due to its less effectiveness.
Explanation:
Azithromycin would be a poor candidate to inhibit SARS-CoV2 due to its less effectiveness. Azithromycin has no effect on the virus because this antibiotic can only attack on the structure of bacteria. Azithromycin is an antibiotic which is used for the treatment of a number of bacterial infections not viruses. They are not designed to destroy the structure of virus but for the bacteria.
In cell culture experiments, purified B cells expressing IgM can be induced to switch to producing IgE by stimulating them with an antibody to CD40 (a stimulatory antibody) plus the cytokine IL-4. In an individual undergoing an immune response, these signals would normally be provided by:
Answer:
TFH cells in the germinal center
Explanation:
The Tfh cells, present in the germinal center, are responsible for maturing and stimulating the class change of immunoglobulins (such as the change from IgM to IgE). This change could stimulate the new classes of immunoglobulins to act with stimulating antibodies to produce an immune response.
It is important to point out that the germinal center is the activated point of a lymphoid follicle that contains B and T lymphocytes, which act in the memory of the cells of the immune system.
What is responsible for the red tide phenomenon? It is a phenomenon that usually coincides with storm surges; the name comes from the red kelp that often washes ashore as a result of rough weather. Red tide occurs in patches of water where certain species of dinoflagellates flourish. They are so abundant that the water becomes discolored and takes on a red hue. Red tides occur once a year and in accordance with the lunar cycle. The water appears red as a result of reduced levels of photosynthetic pigmen
Answer:
Red tide occurs in patches of water where certain species of dinoflagellates flourish.
Explanation:
Red tides refer to the noticeable microalgae proliferation that can be recognized for being a big spot in the sea of a characteristic coloration. This phenomenon is caused by two microalgae groups: diatoms and dinoflagellates, both part of phytoplankton.
Red tides occur when certain environmental factors -such as temperature, light, nutrients availability, ph, etcetera- favor the overproduction of these organisms. These species produce toxins that turn to be dangerous for other animal species that feed on them.
Because these microorganisms produce pigments, their accumulation on the sea surface can be noticed as reddish, brown, or greenish color spots of variable extension.
Two lizards with different coloring exist within the same ecosystem. One lives in the trees, and the other prefers hiding among rocks. They are separate species because
they behave differently
Othey have different characteristics
Othey cannot successfully reproduce
Othey exist within the same ecosystem
Natural selection is that the process through which populations of living organisms adapt and change.
What are the adaptations behavior in organisms?
Many animals are well adapted to biotic and abiotic conditions due to behavioral, physiological, or structural adaptations that increase their chances of survival and reproduction.
Behavioral - responses made by an organism that help it to survive/reproduce..
Physiological - a bodily process that helps an organism to survive/reproduce.Structural - a feature of an organism’s body that helps it to survive/reproduce.Thus, we can conclude that the correct option is (b).
They are separate species because they cannot successfully reproduce.
which means they have different adaptation methods.

Proteins are three dimensional molecules made of strands of amino acids (imagine a ball of string). There are 20 different amino acids used in proteins found in living organisms. Some of these amino acids are polar and others are nonpolar. Where would a series of nonpolar amino acids most likely be located in a protein that is found in the cytosol of an animal cell
Answer:
A series of nonpolar amino acids would most likely be located in the interior region of the tridimensional molecule.
Explanation:
Proteins are formed by linearly arranged amino acids, each with a side chain: the R-group.
Of the 20 different amino acids that compose the proteins, about half of them -10- are non-polar. Their R-groups are not stable if they are in contact with water, meaning that non-polar amino acids are hydrophobic.
When proteins are synthesized, they acquire a three-dimensional structure that makes them more stable. Lineal polypeptides get folded and turn into a shape that makes them more stable in the environment and capable of accomplishing their biological role. When they are in an aqueous media, their bent shape leaves the hydrophilic R-groups in contact with water. The hydrophilic R-groups stick in the center of the polypeptide, facing the protein interior, and avoiding interaction with water.

) An allosteric interaction between a ligand and a protein is one in which: (3 pts) A) binding of a molecule to a binding site affects binding of additional molecules to the same site. B) binding of a molecule to a binding site affects binding properties of another site on the protein. C) binding of the ligand to the protein is covalent. D) multiple molecules of the same ligand can bind to the same binding site. E) two different ligands can bind to the same binding site.
Answer:
B) binding of a molecule to a binding site affects the binding properties of another site on the protein.
Explanation:
In an allosteric interaction between a protein and a ligand, the ligand binds to a site in the protein. As a result, there is a change in the properties of other active sites on the protein. These active-site changes may or may not allow the protein to bind to other molecules. There is a change in the protein that affects the affinity of the active site for other molecules. The affinity on the active site increases if the protein binds to an activator and decreases if the protein binds to an inhibitor molecule.

Sediment deposition will occur along the inner meander bends where the velocity is low.
The graphs below show the change in temperature and salinity of a region of ocean as an instrument is lowered below the surface. Depth is measured in kilometers below the surface, temperature in degrees Celsius, and salinity in parts per thousand.
What is the most valid conclusion regarding ocean salinity based on the data?
A. Ocean salinity is not related to water temperature.
B. Ocean salinity changes with depth at a steady rate throughout the entire water column.
C. Ocean salinity increases as ocean temperature decreases.
D. Ocean salinity is more stable at higher temperatures than at lower temperatures.
Answer:
B. Ocean salinity changes with depth at a steady rate throughout the entire water column.
Explanation:
The data in the graph shows that Ocean salinity changes with the depth at a steady rate throughout the entire water column because when the water table rises it brings salts with them at the top so there is high concentration of salts in the upper layers as compared to other layers and going deep in the soil the concentration of salts becomes very low due to upper movement of salts.
Answer:
B. Ocean salinity changes with depth at a steady rate throughout the entire water column.

According to the ESRT, the rate of temperature increases below the Earth's surface is greatest between depths of
Answer:
Between depths of tectonic plate boundaries and the outer core.
Explanation:
The rate of temperature increases below the Earth's surface is greatest between depths of tectonic plate boundaries and the outer core. At the depth, some of the heat comes from the Earth's core while most of the heat comes from decay of radioactive elements, mainly uranium, thorium and potassium that is located in rocks of the crust. So we can say that the the increase in temperature with depth varies with the chemical composition and age of the rocks.
After a check-up, Josephine's doctor told her that she had mild anosmia and that she can only distinguish about two thirds of the smells that most adults can.
Answer:
Yes.
Explanation:
Yes, she can only distinguish about two thirds of the smells because of the mild anosmia while on the other hand, if she has full anosmia she loss the ability of smell. Mild anosmia is the disease which takes half or some part of the ability but in the case of complete or full anosmia, the patient has lost the ability to smell completely so that's why mild anosmia enable her to distinguish about two thirds of the smells as compared to full loss of smell ability.
