A plant may close and open its stomata to prevent excess water loss and maintain homeostasis.

Homeostasis is termed as the tendency of organisms to maintain and automatic regulation of their internal environment to be in a stable condition.

We say that the plant is in stable condition when the fluid balance and body temperature are being kept in to a pre-set limits which include calcium ions, potassium, sodium and PH of extracellular fluid.

The natural resistance which changes the optimal condition brings about homeostasis.

Proteins are polymers of _____. Proteins are polymers of _____. Nucleotides hydrocarbons amino acids ch2o units glycerol request
Nina [5.8K]

Proteins are polymers of amino acids. There are a fixed set of amino acids that are involved in the making of a protein. These amino acids are varied in number and type to give rise to different combinations in a polymer. This creates a diversity of protein molecules.

The amino acids link to other amino acid in the polymer through the formation of a peptide bond between them. It forms when the carboxylic group of one amino acid molecule reacts and binds to the amino group of the other molecule.
