The hormone insulin and its effect on the body is an example of _[blank]_.
Nana76 [90]

Answer:

negative feedback

Explanation:

Insulin reduces blood sugars when the levels are high in the blood. The hormone  is produced by the pancreas and binds on receptors of cells. This initiates cell signaling mechanisms that signal the cell absorb sugars. When the blood sugars get back to normal, insulin production is reduced.

Reika [66]
The question is:
What may be observed as a result of the described mutation in an individual? 

<span>1) Skin cancer due to UV rays </span>
<span>2) Darker blue pigmentation </span>
<span>3) A lack of alterase for other functions it may serve </span>
<span>4) The release of a different pigment color

The correct answer is B.
In this theoretical molecular cascade, we have three key parts, the blue2 gene, the blue2 operator and the enzyme alterase.
The enzyme alterase stops the expression of the blue2 gene by binding  to its operator, and therefore the blue pigment protein.
The blue2 operator has a specific binding spot for alterase. If this binding spot is changed due to a conformational change, the alterase would not be able to bind to the operator and the blue2 gene could express undisturbedly, resulting in increased concentration of the blue pigment protein.</span>

During a meal, the __________ nervous system stimulates digestive activity and slows heart rate. during exercise, the __________
Licemer1 [7]

Answer:

During a meal, the parasympathetic nervous system stimulates digestive activity and slows heart rate. During exercise, the sympathetic nervous system inhibits digestion and increases heart rate.

<h2>What roles do the sympathetic and parasympathetic nervous systems play in the performance of an individual?</h2>

The two components of the autonomic nervous system are the sympathetic and parasympathetic nervous systems.

They are not in our control and acting against their will. The activities of the heart, lungs, digestive system, urinary system, perspiration, salivation, and sexual function are all under their control.

The thoracic and lumbar spine cords are the genesis of the sympathetic nervous system.

(Lumbar outflow from the thorax)

The cranial nerves of the brain and the sacral region of the spinal cord give rise to the parasympathetic nervous system.

The cranio-sacral outflow

On the effectors that they act on, they have opposing effects. The overall overview of how they work is as follows:

  • The sympathetic nervous system is what causes the "fight, flight, or fear" response. It often activates in emergency circumstances, and action is taken right away. It is heavily weighted toward the body's emergency and survival reactions to a dangerous stimuli. During sympathetic stimulation, there occurs dilation of the pupils, a rise in heart rate, dilation of the bronchi, dilation of the sweat glands, etc. It is accountable for both the retention phase of pee in the bladder and the erection phase of sexual stimulation.
  • The parasympathetic nervous system is in charge of the "rest and digest" phase. It helps with digestion and the relaxation response and is primarily engaged during resting and pleasure moods. The pupils close, the pulse rate and breathing slow down, digestive juices start to secrete, and bowel movement is improved. It is in charge of ejaculation during sexual activity and aids in urination by contracting the bladder.

As a result, it is clear that the sympathetic and parasympathetic nervous systems are essential to human existence. Even while the autonomic system cannot be consciously controlled, some people who practice yoga and meditation have developed the skills necessary to gradually regulate some bodily processes, including heart rate, body temperature, and digestive processes.

In anatomical, directional terminology, the esophagus is _________ to the mouth.
nadezda [96]

<u>Complete Question:</u>

In anatomical, directional terminology, the esophagus is ------------- to the mouth.

a.Superior

b.Lateral

c.Medial

d.Posterior

<u>Correct Option:</u>

In anatomical, directional terminology, the esophagus is<u> medial</u> to the mouth.

<u>Option: C</u>

<u>Explanation:</u>

  • The anatomical directional terminology is necessary to define the relative positions of different physical components.
  • Devote these words to recall in order to prevent ambiguity when you research or explain the positions of various parts of the body.
  • The terms consist roots, prefixes, and suffixes. The source of a word often relates to an organ, tissue or condition while the root is most often defined by the prefix or suffix.
  • The center of the body or its orientation towards the west is understood as medial.
