so what is the answer?

The phylum Echinodermata , which contains about 6000 species, gets its name from the Greek, literally meaning "spiny skin." Many echinoderms actually do have "spiny" skin, but others do not. This phylum exists exclusively in the sea, and cannot be found on land or in fresh water. All echinoderms have one thing in common: radial symmetry. This means that the creatures have appendages (or body construction) which point outward from the center of the body like the spokes on a bicycle wheel. Furthermore, these appendages usually occur in multiples of five, although there are a few exceptions. There are several well known members of this group, like sea stars and sea urchins. The radial symmetry is obvious in these creatures.

You did not include the flow chart,  but I was able to get it in a similar question.

I have edited the flow chat, by filling the white targets with the corresponding label indicating what happens at each step, and also the blue targets with the corresponding label indicating the plant gene functions that must be active at each step.

I also marked the labels with the letter on the corresponding target.

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.

Which of the following hormones inhibits gluconeogenesis, the formation of glucose from noncarbohydrate sources such as amino ac
zaharov [31]

Answer:

The correct answer will be option- Insulin.

Explanation:

Gluconeogenesis is the process of formation of sugar glucose from the non-carbohydrate sources during the less or no intake of carbohydrate from the diet.

Gluconeogenesis is controlled by a feedback mechanism which could be positive or negative. The positive feedback is controlled by the hormones like  epinephrine, cortisol and glucagon but insulin shows negative feedback mechanism and inhibit the process.

Thus, option- Insulin is the correct answer.
