Estrogens from the vesicular follicle trigger an LH surge from the anterior pituitary. This is an example of: Estrogens from the
brilliants [131]

Answer:

The correct answer is: positive feedback.

Explanation:

Positive and negative feedback are terms that are used to define the way a system is regulated by its products. For example, when the production of a certain substance <u>inhibits</u> its producer that is called <u>negative feedback</u>. On the other hand, when a substance <u>stimulates</u> its producer to keep secreting said substance, this is called <u>positive feedback</u>.

Estrogen is a hormone of great importance in the female reproductive cycle and is secreted by the follicle cells in response to the presence of FSH (follicle-stimulating hormone), released by the anterior pituitary when stimulated by the GnRH (gonadotropin-releasing hormone).

Estrogen appears at the beginning of the cycle to stimulate the development of the ovarian follicles, and the hormone levels continue to rise as the cycle advances. Up until the 14th day of the cycle, estrogen has a negative feedback on GnRH and FSH, but then it makes an abrupt change to now exert positive feedback on GnRH to stimulate the release of LH (luteinizing hormone), which will be responsible for ovulation.

During metabolism the complete of one molecule of glucose results in a maximum yield if 38 molecules of
Bond [772]

During cellular respiration, which is a part of metabolism, one molecule of glucose produces a maximum yield of 38 molecules of ATP (adenosine triphosphate). ATP is the energy form that cells use to function and has also been often called the "currency" of the cells.

The whole process begins with breakdown of food by the digestive system right down to their monomer units. Carbohydrates are broken down into glucose, which is carried by blood to all cells of the body.

Each cell takes in glucose and breaks it down through the respiration process that begins with glycolysis in the cytoplasm which yields 2 ATP molecules, then onward into the mitochondria of the cell where Krebs cycle and electron transport chain processes generate 34 to 36 more molecules of ATP.

A high olecranon process locks the elbow into place when used in locomotion. This image of a human shows a dislocation of the ul
Zinaida [17]

Answer:

The type of locomotion that would benefit from having a high olecranon is suspensory (option A).

Explanation:

Olecranon is a bony prominence or process associated with the cube bone and is found at the elbow joint in the upper extremities.

The olecranon process blocks the extension of the elbow by fitting into the socket of the humerus bone, allowing the upper limb to be firm and stable for support on elevated surfaces, climbing, or suspensory locomotion.

Elis [28]

Answer:During the process of glycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
