Answer

The correct option is primary structure.

Explantion

A protein is composed of polypeptide chain which are organized into different structure as explain below:

Primary structure

The primary structure of protein is composed of a single polypeptide chain in which amino acids are arranged in linear form. Only covalent bond (peptide bond) hold the structure.

Example

Insulin hormone

Secondary structure

In secondary structure a single polypeptide chain is arranged in beta pleated sheet or in helical form. hydrogen bond and covalent bond responsible for providing stability to structure.

Example

Myoglobin

Tertiary structure

In tertiary structure a single polypeptide chain is arranged in three dimension. covalent bond, hydrogen bond and disulfide linkage help in maintaning this structure.

Example

Secretory proteins.

Quaternary structure

It is composed of more than one polypeptide chain and arranged in three dimension forming a globular structure. covalent bond, hydrogen bond, disulfide linkage, hydrophobic and hydrophilic interaction help in maintaining this structure.

Example

Haemoglobin.

When is the only time a black spider monkey sets foot on the ground

yawa3891 [41]

Answer:

hey have long, lanky arms and prehensile (gripping) tails that enable them to move gracefully from branch to branch and tree to tree. These nimble monkeys spend most of their time aloft, and maintain a powerful grip on branches even though they have no thumbs.

These New World primates are social and gather in groups of up to two- or three-dozen animals. At night, these groups split up into smaller sleeping parties of a half dozen or fewer. Foraging also occurs in smaller groups, and is usually most intense early in the day. Spider monkeys find food in the treetops and feast on nuts, fruits, leaves, bird eggs, and spiders. They can be noisy animals and often communicate with many calls, screeches, barks, and other sounds.

Where are enzymes most active

Dovator [93]

Answer:

The conditions under which a particular enzyme is most active are called the optimum conditions

Explanation:

When an enzyme is most active the rate of the biological reaction it catalyses is highest. The bacterium Thermus aquaticus lives in hot springs. Its enzymes have an optimum temperature of around 70 oC.
