Explanation:
An inversion is a genetic phenomenon that occurs when a chromosome breaks into two genomic sites, thereby the resulting DNA fragment is reversed and subsequently inserted into the same chromosome location. A pericentric inversion occurs when the chromosome breaks are located on opposite arms or sides of the chromosomal centromere. Moreover, crossing over (or recombination) is the exchange of genetic material between non-sister chromatids during gamete production. An inversion carrier, as in this case the woman who is heterozygous for a pericentric inversion, can produce four types of gametes. If there is no crossing over, half the chromatids will produce normal gametes (without the recombination event) and half the chromatids will produce balanced gametes that will transmit the pericentric inverted chromosome. On the other hand, if there is crossing over, half the chromatids will have one duplication on the first chromosome arm together with a deletion on the second chromosome arm, and the remaining half of the chromatids will have an inverse arrangement.

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.

Answer:
Explanation:
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance
Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself
Centrioles play a role in organizing microtubules that serve as the cell's skeletal system. They help determine the locations of the nucleus and other organelles within the cell.
The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.
The cytoplasm is responsible for holding the components of the cell and protects them from damage. It stores the molecules required for cellular processes and is also responsible for giving the cell its shape.

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.

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.

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.
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.
