-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  = 
Rate of change of grade  =  =
 = 
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.

The main benefit of crossing over is that it increases genetic diversity.
<h2>
Crossing over and 
Genetic Diversity</h2>
Crossing over ensures that the daughter cells produced are genetically more diverse than their parent cells. 
The exchange of chromosomal segments makes the chromosomes of the daughter cells to be more sophisticated than that of their parents.
Increased genetic diversity in daughter cells increases their chances of survival as more genes are present in their genomes that could potentially make them more adaptable to the environment. 
In summary, crossing over increases genetic diversity and genetic diversity increases the chances of survival in the face of changing environment.

<span>After you ovulate, your egg is fertile for between 24 to 48 hours and a man’s sperm can survive in the female body for 48 hours. There have actually even been documented cases of live sperm surviving in the female reproductive system for eight days after intercourse!One breast is always larger than the other. Most of the time, it goes without notice but it is typical for breast size to be slightly mismatched. Some women can be born with two uteruses or two vaginas and have no idea until they notice abnormal menstruation or excessive bleeding. You are born with all the eggs you will ever have in a lifetime which can be anywhere from thousands to millions however, only about 300 to 400 of these eggs will mature and be released for fertilization. <span>You ovaries take turns each month releasing eggs.</span></span>
