The production of egg and sperm cells follows a certain sequence of events.

1 answer:

3 0

The production of egg and sperm cells follows a certain sequence of events.

The correct order of those events are:
MEIOSIS, CELL DIFFERENTIATION, MATURE GAMETES.

Meiosis is defined as the process wherein a single cell is divided twice to produce four cells that contains half the original amount of genetic information.

Cell differentiation is defined as the process wherein the less specialized cell becomes a more specialized cell. The haploid cells are the end result of meiosis. They must undergo cell differentiation before they can become mature gametes.

A small family farm has 230 acres of farmland to grow corn . If each acre yields 63 bushels of corn and each bushel can be sold

SashulF [63]

Answer:

$130,410

Explanation:

According to this question, a small family farm has 230 acres of farmland to grow corn. Each acre yields 63 bushels of corn i.e 1 acre = 63 bushels of corn

Also, each bushel can be sold at $9.00 i.e. 1 bushel = $9.00

If 1 bushel = $9.00

63 bushels = 63 × 9 = $567

Since 63 bushels of corn = 1 acre, it means that $567 is made on one acre.

Hence, on 230 acres, 230 × 567 = $130,410 will be made on corn per year

Glucagon is a hormone that is released when the level of glucose in the blood is low. Glucagon uses a G protein signaling pathwa

allsm [11]

NOTE: the steps of the signal transduction pathway to be arranged is in the attached file.

Answer:

The correct signal transduction pathway in order from the releasing of glucagon into the blood to the promotion of glycogenolysis includes:

- Glucagon binds extracellulary to G- protein coupled receptor.

-G protein releases GDP and binds FTP

-Activated G protein activates adenylate (adenylate) cyclase.

-Adenylate cyclase converts ATP to cAMP.

-Cyclic AMP activates protein kinase A

- phosphorylase kinase phosphorylates glucogen phosphorylase, an enzyme needed for glycogenolysis.

Explanation:

As carbohydrates from food consumed is digested, it's end product, the glucose, is assimilated into the cells for energy production through the help of insulin in a process called glycolysis. Excess of glucose is stored in the liver as GLYCOGEN.

In cases where there is reduced sugar in the blood (hypoglycemic state) another pathway (known as glycogenolysis through

GLUCAGON hormone) is initiated to elevate the concentration of glucose in the blood.
