7 0

Answer:

Locomotion is essential for  various internal and external bodily functions

Explanation:

Locomotion is the art through which our body exhibit various functions and also escapes various condition of environment.  

For instance –

a) Through movement of limbs, actions such as running, walking, jumping, crawling, swimming, etc are performed.

b) Movement of body parts and joints helps in taking different comfortable postures.

c) Even some body parts move even when it is not essentially vital for the function being performed such as movement of eyeball and external ear while swallowing food.  

d) Movement of nutrients and blood with in the circulation system and digestive system.

e) Movement of sense organs when exposed to extreme environmental conditions.

The splitting apart of two organic molecules in a polymer and adding back the water parts to make individual monomers again is c
Pani-rosa [81]

The process of dissolving two organic molecules in a polymer and recombining the water molecules to create new monomers is known as hydrolysis.

<h3>What is hydrolysis?</h3>

The molecule is broken in a hydrolysis reaction involving an ester bond, such as the one between two amino acids in a protein. As a result, the water molecule (H₂O) splits into two groups: one that forms a hydroxyl (OH) group with the remaining hydrogen proton (H+) and another that transforms into a carboxylic acid.

Practically speaking, hydrolysis refers to the process of separating compounds when water is present.

Condensation, which is the process by which two molecules combine to produce one bigger molecule, can also be thought of as the opposite reaction to hydrolysis. The outcome of this reaction is that a water molecule is ejected by the larger molecule.

The three primary hydrolysis processes are

  • Salt hydrolysis.
  • Acid hydrolysis.
  • Base hydrolysis.

Increasing the number of stomata per unit surface area of a leaf when atmospheric carbon dioxide levels decline is most analogou
Liono4ka [1.6K]

Increasing the number of stomata per unit surface area of a leaf when atmospheric carbon dioxide levels decline is most analogous to a human

B. putting more red blood cells into circulation when atmospheric oxygen levels decline.

<h3>What are stomata?</h3>

The stomata are apertures in the epidermis, each bounded by two guard cells. There are small openings on the lower surface of the leaves. These pores are called stomata. Loss of water from the stomata creates an upward pull, that is suction pull, which helps in the absorption of water from the roots. That is helpful for the transpiration process. They help in exchange for gases. Any of the tiny pores or openings in the epidermis of leaves and young stems are referred to as a stomate, sometimes known as a stoma, the plural of which is stoma or stomas. On the underside of the leaves, stomata tend to be more numerous. They enable the exchange of gases between the atmosphere outside and the leaf's branching network of interconnected air canals.

<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.
