-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.

<span>Answer: “Comparing the mitochondrial DNA between different eukaryotes to see how closely they are related.”</span>
The endosymbiotic theory focuses on the origin of two eukaryotic organelles that have bacteria characteristics (mitochondria in animals and chloroplasts in plants). These two are s are believed to have developed from symbiotic bacteria.
<span>In designing an experiment that would support the endosymbiotic theory, the statement that would provide the best evidence is comparing mitochondrial DNA between different eukaryotes to see how closely they are related.</span>
Answer:
Ever since the existence of life of humans on Earth, the humans have been making progress to understand themselves and the mother nature.
In the start, the humans were hunter- gatherers. Hunter- gatherers can be described as humans which use wild life plants and animals for food. The humans used to live in jungles and eat the wild- life plants and animals. They used leaves from the trees to cover their bodies. Heat was produced by rubbing the rocks.
After this time, the humans learned the techniques of cultivating plants for food. They started cultivating crops and depend on them for living. During this time, humans learned the art of farming and agriculture. But they couldn't understand the effects of various pathogens infecting the crops and humans at that time.
After this time, humans learned the art of preserving foods in different forms like pickles etc. They also learned that certain types of plants could be used to treat wounds and other diseases.
With the passage of time, people learned to make and use machinery for making their tasks easier. The usage of machinery progressed rapidly and the industrial revolution began. People became more diverted to this sector rather than farming. They started to move towards the cities to find better jobs in industries.
Life after industrial revolution was much easier as humans had made a lot of equipments which aid them to have a better life style. Science has been developing since that time day by day.
