Biological diversity is the variety of species in a given area. If a new species is added there are more species and therefore greater biological diversity and if one goes extinct there are less species and therefore less biological diversity.
The system is called Taxonomy and was made by Swedish botanist Carlous Linnaeus

Answer:
a. 8.1 milligrams
b. 40.07 hours
c. 8.859 milligrams
Explanation:
If a person takes a prescribed dose of 10 milligrams of Valium, the amount of Valium in that person's bloodstream at any time can be modeled by

Where A(t) = amount of Valium remaining in the blood after t hours
t = time or duration after the drug is taken
a. we have to calculate the amount of drug remaining in the bloodstream after 12 hours


= 10×0.81253
= 8.1 milligrams
b. In this part we have to calculate the time when A(t) = 5 milligrams


0.5 = 
Now we take natural log on both the sides of the equation.
ln(0.5) = ln(
-0.69314 = -0.0173t
t = 
t = 40.0658
≈ 40.07 hours
c. In this part we have to calculate the rate, by which amount of drug will decay in the bloodstream after 7 hours.


= 10×0.8859
= 8.859 milligrams
Answer:
mutation
Explanation:
If any part of the DNA is changed, such as the base pairs, then it would result in the mutation of the DNA, causing it to carry out a different function
