16
Q

These are based upon the use of biological responses as detection system for biological active substances.

A

Bioassays

17
Q

It is usually the first step in development process.

A

Research and development

18
Q

refers to an experimental procedure where varying doses of a substance are systematically applied to observe the graded response of a biological system.

A

Graded assay

19
Q

this response is in the form of “all or none” means no response or maximum response.

A

Quantal Assay

20
Q

relationship between the dose and response of each preparation is first ascertained. Then the dose corresponding to a given response is obtained from the relation for each preparation separately.

A

Indirect Assay

21
Q

Doses of standard and test preparations are sufficient to produce a specified response, and can be directly measured.

A

Direct Assay
