There are often not more than one or two independent variables tested in an experiment, otherwise it is difficult to determine the influence of each upon the final results. There may be several dependent variables, because manipulating the independent variable can influence many different things.

A student's grade goes from a 95 to a 65 in 3 weeks. Calculate
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.

Agonist/antagonist
 Agonist are drugs that bind and activate a receptor with effecting the response.If the effect results in maximum response it is considered as full agonist. However if the drug that binds to the receptor results only into partial efficacy in relation to the full activation of the receptor, this is considered as partial agonist.

Antagonist are drugs that blocks a biologic response of a hormone or another drug. They usually have affinity to the receptors but has no efficacy. This drug will just inhibit the activation of the receptors by the aganist.

If a DNA molecule is found to be composed of 35% thymine, what percentage of cytosine would be expected, and why?
-Dominant- [34]
We use Chargaff's rule to get the answer. [A] + [G] = [C]+ [T].    [A] + [G] + [C] + [T] = 100% Where is A is Adenine, G is Gaunine, T is Thymine and C is Cytosine. In DNA, Adenine always pairs with Thymine, and Guanine always pairs with Cytosine. Therefore if Thymine is 35%, then Adenine will also be 35% to make 70% in total. The remaining percentage will be 100% - 70% = 30%. The 30% will be shared equally among Cytosine and Guanine, at 15% each. Therefore Cytosine will be 15%
