A wet handkerchief is kept on the forehead of person suffering from fever. why?​

Answer:

A) Nerve and muscle cells use more energy

Explanation:

Mitochondria are located near sites of high ATP utilization such as in muscle cells and neurons.

In the cells of the heart muscle these mitochondria are located near the contractile apparatus, which is where the hydrolysis of the ATP is carried out to generate the necessary energy in the contraction. In musculoskeletal cells the number of mitochondria is increased between 5 and 10 times when the muscle is exposed to continuous contraction.

In the neuronal cells there is a high workload suffered by the cell and a high energy expenditure

Answer: The correct answer is aqueous solution

Explanation:

The mixture is best described as AQUEOUS SOLUTION because water is the solvent used to dissolve the various solutes (sugar, flavorings, coloring agents, and carbon dioxide). The resulting mixture is a aqueous solution known as Soda.

Polysaccharides play crucial roles in living things due to their diverse functions and properties. As complex carbohydrates made up of multiple sugar units, they serve as important sources of energy and structural components in organisms.

1. **Energy Storage:** One primary role of polysaccharides is to store energy for short-term and long-term use. Plants store excess glucose in the form of starch, while animals store it as glycogen in the liver and muscles.

2. **Structural Support:** Polysaccharides provide structural support in cell walls of plants, algae, and some bacteria. For example, cellulose forms the rigid cell walls of plant cells, giving them shape and support.

3. **Protection and Lubrication:** Some polysaccharides, like chitin found in the exoskeletons of insects and crustaceans, provide protection and structural support. Hyaluronic acid, a polysaccharide in connective tissues, acts as a lubricant and shock absorber.

4. **Cell Recognition:** Polysaccharides are also involved in cell recognition and signaling processes. They form part of cell surface markers and play essential roles in immune responses and cell communication.

Overall, polysaccharides are essential biomolecules that fulfill diverse functions, contributing to the proper functioning and structure of living organisms.
