As her professor distributed the mathematics test to the class, Blair's heart started to pound and her palms began to sweat. These physiological reactions were activated by her ________ nervous system. Group of answer choices central endocrine sympathetic somatic parasympathetic

Answers

The answer is the Sympathetic nervous system as a Group of answer choices central endocrine sympathetic somatic parasympathetic shows these symptoms.

The sympathetic nervous system is a part of the self-sustaining fearful device which controls the involuntary frame capabilities such as coronary heart rate, breath rate, perspiration, etc. The sympathetic is in particular answerable for the boom withinside the feature of frame capabilities while the frame perceives a risk. When confronted with a risk or distress, the sympathetic nervous system initiates physiological reactions called the “combat or flight” response, thereby growing the frame’s alertness to such risk. Examples of improved frame capabilities or “combat or flight response” consist of improved perspiration and improved coronary heart rate, as exhibited via way of means of Blair.

What is the sympathetic nervous system?

The sympathetic nervous system directs the body's speedy involuntary reaction to risky or disturbing situations. A flash flood of hormones boosts the body's alertness and system coronary heart rate, sending greater blood to the muscles.

Hence conclude the sympathetic nervous system is the answer.

Answer:

sympathetic nervous system

Explanation:

The sympathetic nervous system is part of the autonomous nervous system which controls the involuntary body functions as heart rate, breath rate, perspiration etc. The sympathetic nervous system is specifically responsible for the increase in the function of body functions when the body perceives a threat. When faced with a threat or distress, the sympathetic nervous system initiates physiological reactions known as the “fight or flight” response, thereby increasing the body’s alertness to such threat. Examples of increased body functions or “fight or flight response” include increased perspiration and increased heart rate, as exhibited by Blair.

Before starch can enter a cell, it must be(1) absorbed by simple sugars
(2) diffused into simple sugars
(3) digested to form simple sugars
(4) actively transported by simple sugars

Answers

Starch are macromolecules that are made of monomers that are simple sugars. Cells are microscopic and they can only absorb small substances. Therefore starch needs to be digested in other words broken down into simpler substances that can be taken in by cells. Therefore before starch can enter a cell it must be 3) digested to form simple sugars

Answer:

The correct answer is 3. Hope this helps! Best of luck to you. :)

Explain how a starfish's body plan and anatomy's function very essential to its survival.

Answers

All starfish limbs are designed to do have the same function, which means that in case a limb is severed, the other arms can make up for it until the arm regrows, which it does after a while. They are all connected to the center of the starfish which should not be damaged.

Most cells that experience mutations or damage _________. Select one: a. become cancer b. undergo apoptosis c. become a malignant tumor d. undergo metastasis

Answers

A. Become cancer because in the process of mitosis (cell replication) idlf the cell replication does not work properly and keep going on and on it will begin creating mutations to help it replicate causing cancer to happen.
Ex: let's say you have a paper cut. Your blood cells must replicate in order to close that gap in your body. They begin replication but if they get out of control and begin creating mutations it will turn into cancer.

Which of the following statements best describes the structure and function of a carbohydrate?A. Carbohydrates are made up of starchy monomers and are used for structure, protection, and reproduction.
B. Carbohydrates are made up of sucrose molecules that are important for transportation and protein synthesis.
C. carbohydrates are large molecules made up of monosaccharides and are used by organisms for energy storage.
D. Carbohydrates are long, winding molecules made up of amino acids and are important in the synthesis of fats and hormones.

Answers

Answer: The correct answer is C. Carbohydrates are large molecules made up of monosaccharides and are used by organisms for energy storage.

Carbohydrates are the large group of organic compounds, which are comprised of Carbon, hydrogen, and Oxygen. They mainly include simple sugar (like glucose, fructose) and starch ( present in food like potato, grains).

They are the most essential and readily available source of energy for all life forms.

Complex carbohydrates ( polysaccharides) like starch are made up of simple sugar called monosaccharide ( like glucose).

Thus, option C) is the right answer.


Final answer:

Carbohydrates are large molecules made up of monosaccharides and are used by organisms primarily for energy storage.

Explanation:

The statement that most accurately describes the structure and function of a carbohydrate is 'Carbohydrates are large molecules made up of monosaccharides and are used by organisms for energy storage.' Carbohydrates are indeed large, complex molecules that are composed of smaller subunits known as monosaccharides.

They serve several essential functions in organisms, one of the most critical one being the storage and provision of energy. When organisms ingest carbohydrates, these molecules are broken down and converted into glucose, which is then used to fuel various cellular activities.
