Integers and Their Properties

An integer is a whole number, both positive and negative, including zero.
A positive number's additive inverse is its negative counterpart.
The set of integers is denoted by the symbol $\mathbb{Z}$ in mathematics.
A subset of the integers can include natural numbers and their negatives.
All integers are also real numbers, but not all real numbers are integers, like fractions or irrational numbers.
The set of integers has infinite cardinality.

Nutrients and Their Importance

Nutrients are substances that provide essential elements for growth, metabolism, and overall health.
They can be incorporated into various biological compounds and metabolic pathways within organisms.
Animals and humans require dietary intake of nutrients for optimal functioning and development.
Common examples of end-products from nutrient metabolism include energy (ATP), amino acids, and fatty acids.
Essential nutrients for animals include vitamins, minerals, essential amino acids, and fatty acids, vital for processes like cell function and tissue repair.
