Kisspeptin is a protein in humans that has an important role in initiating secretion of the releasing factor gonadotropin-releas

ing hormone (GnRH). Endocrinologists are finding that the protein kisspeptin and its receptor are central to sexual maturation at puberty. Neurons that release kisspeptin carry estrogen receptors. If this is a negative feedback system, high levels of estrogen would be expected to: decrease kisspeptin synthesis. increase kisspeptin synthesis. neither increase nor decrease kisspeptin synthesis because steroid hormones do not affect protein synthesis.

Answer:

decrease kisspeptin synthesis

Explanation:

Kisspeptin is a protein involved in the regulation of gonadotropin-releasing hormone (GnRH): it stimulates the secretion of GnRH. GnRH than stimulate the release of gonadotropins such as follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary gland. FSH stimulates the  production of estrogens by the granulosa cells of the ovarian follicles.

In negative feedback system, high levels of estrogen will bind to their receptors on neurons that release kisspeptin and inhibit its further release.

What type of reaction occurs when large carbohydrate molecules are broken down into smaller sugars? select one:
seraphim [82]
Answer: D

Carbolic reactions breaks larger substances to smaller ones.

Anabolic reactions forms larger compounds from smaller units.

DNA synthesis does not involve breaking down of sugars.

Dehydration is a umbrella term used for reactions that releases water as a byproduct. In the case of sugars, they are held by Glycosidic bonds. To break them, hydration is needed as 1 water molecule breaks 1 glycosidic bond. The process of forming large units of sugars involves dehydration to form the glycosidic bonds. Therefore option d is wrong.

DNA guiding production of protein is definitely wrong as this process doesn't cause sugars to break down at all.

Nerissa is using immunostaining to identify different protein molecules on the cell of a pathogen. Which best describes the proc
Alja [10]

Answer:

She will add color dye to antibodies, and the antibodies will attach to the antigen of the pathogen.

Explanation:

Immunostaining is the process where the antibodies for a specific pathological antigen is combined with fluorescent dye or any other indicator, like enzyme. Fluorescein are common staining materials used because it is easily detectable under UV light. This antibody coated with indicator thus bind to the specific pathogen or protein and help in its identification. Also the pathogenic cell fixation is done to facilitates clear and precise identification.

An example of Hector's somatic sensory system is in control is well demonstrated when after a long run, his body is sweating.

Answer: Option A

<u>Explanation:</u>

The somatic sensory system of the body refers to the living sensory system which is the system of sending response to the body in response to the stimuli felt or sensed. The motor neurons and sensory neuron comprises the system and when ever there is a change in the body outer or inner core which forms an stimuli, signals the somatic sensory system, and a response is signalled back.

So, when the Hector is running for a long time, the body heats up due to constant retraction and expansion of the muscle due to friction, the glucose molecule as energy is also exhausted, so counter the change, sensory system, cools the body from the heat produced, the cooling of the body is achieved by sweating. Therefore, Option A is the correct answer.

alukav5142 [94]

The question is incorrect. The correct question is as follows:

Assuming that a clean-catch, midstream urine was processed in the CML, which of the following colony counts is (are) indicative of a urinary tract infection?

Answer:

100,000 CML/mL and >100,000 CFU/mL.

Explanation:

Urinary tract infection (UTI) may be defined as the infection that occurs at the excretory organs of the body especially in the lower urinary tract. This infection is most common in woman.

The clinical micrology laboratory that diagnose the infection of bacteria, fungi and virus. If the number of colony units in the diagnosis of UTI is between 00,000 CML/mL and >100,000 CFU/mL, this confirms that individual is suffering from UTI.

Thus, the correct answer is 100,000 CML/mL and >100,000 CFU/mL.
