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.

Answer:
The sample size of the animal was too small , not large enough to conclude that the effects of the chemicals on Salamander was the actual cause of toxicity and weight loss.
It is possible that the drop in weight may be as a result of other environmental factors; agitation from background noise and sudden exposure to new environments,, fluctuation in temperature of the surrounding environments , lack of feed supply or others
However, if there was many salamanders available; and most reacted to the chemical exposure in the same way then it can be concluded that, toxicity of the chemical is the causative factor.
Explanation:
I believe it’s grass, just because it’s important for growing food
The total mass of A and C which are glucose and oxygen, is equal to the total mass of B and D, which are water and Carbon dioxide.
the law of conservation states that no energy or matter should be lost during a reaction therefore total masses should be equal so you're looking to 2 numbers that equal each other when added and the only 2 are A and C equal B and D
In respiration we know that the waste products are water vapor (H2O) and carbon dioxide.
Which makes the last statement correct.
