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.

Which of the following substances would NOT transport readily in blood?
Levart [38]

The substance that would not transport readily in blood is : Triglycerides ( B )

<u>Although your question lacks some data below are the missing options</u>

  1. Fibrinogen
  2. Triglycerides
  3. Monosaccharides
  4. Albumin
  5. Carbohydrates

Triglycerides are not readily transported in blood but it is contained in dietary fat which is been absorbed by the body through the intestine in the form of chylomicrons ( triglyceride-rich lipoproteins ).

When the chylomicrons gets to the liver, the liver disassociates the Triglycerides from the chylomicrons that is needed by the body for energy.  

Hence we conclude that the substance that would not transport readily in blood is Triglycerides.
