Answer:


Active transport: movement against a gradient To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the proper concentrations of ions and molecules in living cells.

KiRa [710]

Answer:

<u> Essential</u> nutrients cannot be synthesized by the human body but are required for optimal functioning. Therefore. They must be obtained from food. Omega-3 fatty acids are prime examples.

You consume macronutrients (water. proteins, carbohydrates, and fats) in large quantities as opposed to <u>micronutrients</u> which you consume in small quantities

<u>Dehydration</u> can develop very quickly when exercising in hot/humid weather conditions.

<u>Proteins</u> are also called 'bodybuilders" due to their function within the body. <u>Amino acids</u> are the building blocks of proteins.

Explanation:

Essential nutrients are those nutrients that are required for the proper functioning of the body but cannot be synthesized by the body.  They are obtained from external sources such as vegetables or synthesized artificially in the laboratories. Micronutrients as the name implies are taken in small amounts. Examples are the different types of vitamins.  

Dehydration occurs when a person loses a good amount of water through sweating or urination. It can easily occur while exercising in hot weather conditions. Proteins repair the cells in our body and are, therefore, rightfully referred to as bodybuilders. Amino acids form proteins.
