steposvetlana [31]

-10grade/week

Explanation:

Given parameters:

Initial grade = 95grade

Final grade = 65grade

Time = 3weeks

Unknown parameter:

Rate of change of grade = ?

Solution:

Rate is defined as the change of a quantity with time.

 Rate of change of grade  = \frac{Final grade - Initial grade}{Time}

Rate of change of grade  = \frac{65 - 95}{3} = \frac{-30}{3}

Rate of change of grade = -10grade/week

The rate of change of the student's grade is -10grade/week. It implies that the grade of the student reduces by 10unit per week.

Allow for the identification of many toxins in a small amount
lilavasa [31]

Answer:

O4) Screening tests

Explanation:

The screening test is used to make early detection of diseases in order to apply effective treatments. For example, a screening blood test enables the identification of toxins and/or drugs in the patient's system in a relatively low amount of time (generally 24 hours). This bioassay is used for the toxin determination of the effluent sample (i.e., a sample collected and analyzed to evaluate system performance) to the tested species. The screening test generally consists of applying two treatments (i.e., one effluent sample and one control).
