Answer:
-The size of sheep olfactory bulb is two to three time larger than humans olfactory bulb.
-Sheep has strong sense of smell that helps the sheep to acquire food.
Explanation:
- The size of the sheep brain is much smaller than humans but sheep has well developed olfactory bulb than humans. The human brain is more circular in shape whereas sheep brain is more extended.
- The well developed olfactory bulb in sheep helps the sheep to find the food. Sheep has strong sense of smell due to large olfactory bulb. Sheep can easily find the location of food located farway from it as the sheep has strong sense of smell.
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:
Carbon dioxide can be transported through the blood via three methods. It is dissolved directly in the blood, bound to plasma proteins or hemoglobin, or converted into bicarbonate. The majority of carbon dioxide is transported as part of the bicarbonate system. Carbon dioxide diffuses into red blood cells.
