Answer: Diversity, referring to the state of having many different organisms cohabitate within an area is a desirable outcome for many ecosystems. The presence of a wide spectrum of different organisms allows for more life to be able to thrive in an ecosystem. For example, an ecosystem with a wide array of shrubs, grasslands and forested areas is able to accommodate more life forms than an ecosystem of just forest. This increased capacity to support life directly improves the capacity of the biosphere to support life as well, diversity leading to growth.

Nitrogenous base DNA consists of four unique nucleotides that each contain one unique nitrogenous base—adenine (A), thymine (T), cytosine (C), or guanine (G).
The specific arrangement of these four bases within the DNA of each organism gives that organism its unique traits; here are the arrangements:
-<u>Adenine</u> is paired with <u>Thymine</u> (think of A for apple and T for tree)
-<u>Cytosine</u> is paired with <u>Guanine</u> (think of C for car and G for garage)

21. Lipids
22. Carbohydrates
23. Lipids
Explanation:
Carbohydrates are organic molecules composed of carbon, hydrogen and oxygen. Carbohydrates can be classified into three types: monosaccharides (e.g. glucose), disaccharides (e.g., lactose), and polysaccharides (e.g., starch). Cellulose is a carbohydrate where many glucose rings chain together, while chitin is a polysaccharide consisting of chains of modified glucose molecules.
Lipids represent a diverse group of organic molecules that include, among others, fats, waxes, oils, hormones, etc. Lipids play a role by insulating (and protecting) the body. For example, there is a layer of fats beneath the skin which enables to maintain body temperature relatively constant. In animals, lipids constitute about 50% of the mass of cell membranes. These membrane lipids are mainly phospholipids, glycolipids and cholesterol. There are hormones that derive from lipids such as steroid hormones, which derive from cholesterol. Some examples of steroid hormones are testosterone, estrogen and cortisol.
