The best answer is d - Water.

Plasma is a water solution that is pale yellow in color in which all other parts of the blood are suspended.

Plasma is made up of approximately 92 % water. Proteins, enzymes, glucose, amino acids, minerals, urea, vitamins, uric acid, antibodies, salts and hormones make up the remaining 8% .

Whole blood is composed of 55% plasma. Plasma in blood acts as a solvent for gases, electrolytes, nutrients and important proteins vital to life.

Which level of biodiversity includes species richness and evenness?

Novay_Z [31]

The answer is:

Community Diversity.

Reason Why: Here is an example, say you have 2 communities, community 1 is A, and community 2 is B, Communities A and B contain 5 tree species, However because community B has greater species evenness it has greater species diversity.
Community A is dominated by one of its 5 species and so has lower species diversity than.....community B, which has the same 5 species but in equal proportion.

Richness- Number of Species
Evenness-Relative abundance.

Hope This Helped!
