Dima020 [189]

Answer:

When seen on a Wright-stained peripheral blood film, a young red cell that has just extruded (lost its) nucleus is referred to as a polychromatophilic cell.

Explanation:

On Wright-stained smears, slightly immature red cells that do not have nuclei (reticulocyte stage) look blue-gray because they still have some ribonucleic acid in them (RNA). These cells are commonly referred to as polychromatophilic cells. Most of the time, polychromatophilic cells are bigger than mature red cells, and their blue-gray color makes them different from macrocytes.  Polychromatophilic red cells also tend to lack the central pallor.

When the remaining mRNA and ribosomes are stained with supravital dyes, they make the red cells look like a "reticular" mesh network. This is how the name "reticulocyte" came about. It is to be noted that not all reticulocytes show up as polychromatophils when stained with Wright-Giemsa.

Liono4ka [1.6K]

Answer:

The correct answer is option c. By blocking the enzyme responsible, penicillin stops the bacteria from producing new peptidoglycan.

Explanation:

Penicillins are derived from Penicillium molds. These are a group of antibiotics, used in treating various types of bacterial infections such as urinary tract infections, respiratory tract infections, gastrointestinal infections etc.

These antibiotics also used in treating gonorrhoea, meningitis, pneumonia, syphilis, etc. These antibiotics stop the bacteria from producing new peptidoglycan that blocks the enzyme.

<span>If a nurse notices that an accident victim cannot clench his teeth, there is a good chance that his trigeminal nerve has been affected. This nerve is located inside the brain and its primary purpose is to transmit sensations from a person's face to the brain. Damage to this nerve could cause the patient to be unable to clench their teeth.</span>

Movement of the chromosomes during anaphase would be most affected by a drug that
My name is Ann [436]

Answer:

The options are missing, the options are:

A) prevents the duplication of centrosomes. B) prevents nuclear envelope fragmentation C) prevents shortening of microtubules. D) prevents attachment of the microtubules to the kinetochore. E) prevents nucleosome formation

The answer is C

Explanation:

Cell division is a characteristics of all living cells. Whether meiosis or mitosis, the chromosomes separate in the Anaphase stage. Prior to the anaphase stage is the metaphase, where spindle microtubules attach to the kinetochores of each chromosome and aligns them at the centre of the cell called METAPHASE PLATE.

Thus, since the aligning of chromosomes at the metaphase plate has to do with attachment of microtubules to chromosomes' kinetochores, the drug that will hinder movement of chromosomes to opposite poles will not stop formation of microtubules. Instead, it will prevent the formed microtubules attached to each chromosome from shortening, as it is the shortening of microtubules that facilitates the pulling apart of the chromosomes they are attached to.
