Answer:

Reactant

Explanation:

The substances that are inserted first into a chemical reaction are the reactants. They are at the beginning of the reaction and it is these substances that will react and undergo transformation.

The <u>products</u>, on the other hand, are the resulting substances of the chemical reaction that occurs between two or more reagents.

<u>Catalyst</u> is a chemical substance that does not participate in the chemical reaction (like reactants and products). Its role is to decrease the activation energy and increase the speed of reactions.

<u>Enzymes</u> are organic substances (proteins) that act as catalysts in various metabolic processes of living things.

<h2>What is a sympathetic nervous system?</h2>

The peripheral nervous system and the central nervous system are the two primary divisions of the human nervous system, as shown in the image below.

Two additional parts make up the peripheral nervous system. Skeletal muscle movement that is voluntary is controlled by the somatic nervous system. The somatic nervous system is at action when you choose to bring your coffee cup to your lips; it is doing so by engaging the necessary muscles. The autonomic nervous system, which regulates functions outside of our conscious awareness, is the second part of the PNS.

The parasympathetic nervous system and the sympathetic nervous system are additional divisions of the autonomic nervous system (which you are interested in). They have negative consequences on one another, to put it very broadly. While the parasympathetic neural system largely works to calm the body, the sympathetic nervous system often stimulates the body. Although this is a streamlined perspective, it might be helpful to think about it this way.

The sympathetic branch of the autonomic nervous system speeds up heartbeat, slows down digestion, opens up airways in the lungs to allow for greater airflow, triggers the liver to release glucose, and relaxes the bladder. All of this wakes up the body and gets it ready to "fight."

The parasympathetic division, in contrast, slows the heart rate, tightens the bronchi in the lungs, and boosts blood flow to the digestive system. The phrase "relax and digest" has been used to describe it.

The parasympathetic nervous system's nerves originate from the brainstem and spinal cord, as shown in the diagram. The "ganglia" (collections of cell bodies) of the sympathetic nervous system, however, exist beyond the spinal cord.

It's interesting to note that whereas the sympathetic nervous system activates the body using both acetylcholine (ACh) and norepinephrine (NE), the parasympathetic nervous system solely needs ACh to affect organs.

The sympathetic and parasympathetic nerve systems are autonomic, which means we typically have minimal control over them.

Sunlight is absorbed by the leaves. What two substances are also taken in by the plant for photosynthesis to occur?
dolphi86 [110]

Answer: Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.

melomori [17]
When a muscle contract, it will become shorten. To kick a ball, there are many muscles used for moving the leg. Muscle from the thigh will move the lower leg and the power of kick comes from this muscle group.  The muscle in the lower leg will control the feet and determine whether kick using the front or side of the feet.

Since the muscle in one side contract, the opposite muscle in the muscle pair will be flexed. The muscle in flex condition will be lengthened.

Is it true that the unltimate sorce of energy of all living things is the leaf?
vitfil [10]
The ultimate source of energy for living things is the Sun. Plants and other photosynthetic organisms take the energy from sunlight to make glucose. Glucose is a simple sugar with the molecular formula C6H12O6. Glucose circulates in the blood of animals as blood sugar. It is made during photosynthesis from water and carbon dioxide, using energy from sunlight.
