a. You are startled when a friend pulls a practical joke and spooks you with a loud sound.

b. You move your arms and legs to take an evening walk.

c. Your stomach makes a gurgling sound as it digests your lunch.

d. Feeling a little stressed? You take a few breaths to calm down.

e. You are at the line, waiting for you race to start, and your heart begins to pound.

Answers

A startle reflex (a), digestion (c), breathing (d) and heart pumping (e) are responses of the ANS, while arm/leg movement (b) is a response of the SNS. They are major divisions of the PNS.

The peripheral nervous system (PNS) serves to connect the central nervous system to different organs, limbs, and skin.

The PNS can be divided into Somatic Nervous System (SNS) and Autonomic Nervous System (ANS).

The Somatic Nervous System is responsible for controlling the voluntary movements of the body.

The Somatic Nervous System is responsible for regulating the involuntary movements (reflexes) of the body.

Answers

Answer

To understand the global systems and the changes they undergo in a better way, we can use a model to represent the various ecological processes that occur within the biosphere. One example of a model that we can use is the earth systems model. It can show the causes and effects of global change to provide us with insights and learning about the global system as a whole.

Explanation:

Answer:

To be able to understand global systems and their changes first we must survey them before and relook at the systems and analyze how they have changed and what caused these changes.

Answer:

Explanation:

Mitosis is the only type of cellular division in which number of chromosomes is maintained

What is mitosis?

During the phase of the cell cycle known as mitosis, duplicated chromosomes are physically split in half to form two new nuclei. Mitosis is a method of cell division that results in the production of cells that are genetically similar and in which the total number of chromosomes is preserved. Since this occurs during mitosis, the process is often referred to as equational division.

Mitosis serves a very vital purpose in living creatures, and one of its functions is the regeneration and replacement of worn-out and damaged tissues. Mitosis contributes to the generation of identical copies of cells and, as a result, assists in the process of healing damaged tissue or replacing cells that have been worn out.

what is the difference in solubility of triglyceride and the products of their hydrolysis​

Answers

Answer: Triacylglycerols are the major constituents of oils and fats of both plant and animal origin.

Explanation:

Hope this helps.

The products of hydrolysis of triglycerides are fatty acids and glycerol. While fatty acids, like triglycerides, are insoluble in water, glycerol is soluble in water.

Why are triglycerides insoluble?

Triglycerides are esters of fatty acids and alcohol, mostly glycerol. The fatty acid chains are inked to the glycerol molecules with the help of covalent bonds.

This means that the triglyceride molecule is uncharged and will therefore remain insoluble in water but soluble in organic solvents.

Also, products of hydrolysis of triglycerides are fatter acids and glycerol. While fatty acids will remain insoluble in water, glycerol is soluble in water.

Glycerol is alcohol with 3 hydroxyl groups, this is why it is also called a polyol. They are able to hydrogen bonds with the nearby water molecules.

Therefore, triglycerides and fatty acids are insoluble and glycerol is soluble in water.

(Choice B)

Chlorophylls absorb light energy, which eventually breaks the bonds of water molecules.

(Choice C)

ATP and NADPH are used for carbon fixation.

Answers

Answer:

I think it is Chemical reactions produce glucose, ADP and NADPH

Explanation:

Photosynthesis is a chemical reaction that takes place to convert light energy. The photosynthetic light-dependent reaction forms glucose, ATP, and NADP⁺. Thus, option A is correct.

What is a light-dependent reaction?

A light-dependent reaction is a photosynthetic reaction that occurs in the presence of sunlight and produces chemical energy in the form of NADPH and ATP.

The products of the photosynthetic light-dependent reaction are used in light-independent reactions. In light-dependent, the photosystem gets excited and produces ATP from ETC, leading to reduction of NADP⁺ and photolysis of the water molecule.

Therefore, ADP and NADP+ are produced at the intermediary stage of the light-dependent reaction which makes them different from the light-independent reaction.

During photosynthesis, plants, algae, and photosynthetic bacteriatogether called producerscreate their own food by capturing light energy from the Sun to make molecules of glucose. Organic molecules, including glucose, can then be stored as food to be broken down by cellular respiration when energy is needed. All living organisms perform some kind of cellular respiration.
