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

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

Proteins are also called 'bodybuilders" due to their function within the body. Amino acids 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.

<h2>Vascular and Nonvascular Plants </h2>

Explanation:

Kingdom Plantae on the basis of vasculature is divided into two groups-vascular and non-vascular plants .

Vascular plants or tracheophytes have a proper tissue-level organization and true shoot and root structures like leaves, stem, flowers, root etc
The tissue system or vasculature of vascular plants compromises of vascular tissues like tubular vessels – xylem and phloem

The xylem transports nutrients to various parts of the body from the leaves.
Phloem conducts water and other nutrients from the roots to various parts of the plant .

These are flowering plants that include the phanerogams – angiosperms and gymnosperms and bears flowers and fruits like the cedars, pine, clubmosses, lilies, sunflower etc.
Dicots are with tubular vasculature.

Non-vascular plants or bryophytes with an absence of proper tissue-level organization and true shoot or root systems
Nonvascular plants are small. Their transport mechanism is poor due to lack of vascular tissues
These plants are lack proper shoot or root system.
It includes mosses, hornworts etc.
Monocots are plants with scattered tube-like vessels .
