PLEASE HELP!!!!<br> How does the FDA regulate the animals?
Gnoma [55]

Whenever a new drug, device, or food, is developed for use in animals, It has to be approved by the FDA before it can be sold and marketed to the public.

Don't use the exact words, I copied it from an FDA website so change the wording first before you submit. Good luck Lol.

6. A scientist measures the circumference of acorns in a population of oak trees
melisa1 [442]

Answer:

6. 2 cm

8. Greater than 2 cm and less than 2 cm

Explanation:

Complete Question

6. A scientist measures the circumference of acorns in a population of oak trees and discovers that the most common circumference is 2 cm. What would you expect the most common circumference(s) to be after 10 generations of stabilizing selection?

-2 cm

-Greater than 2 cm or less than 2 cm

-Greater than 2 cm and less than 2 cm

-Can't tell from the information given

8. Refer to question 6, but this time answer what you would expect after 10

generations of directional selection.

-2 cm

-Greater than 2 cm or less than 2 cm

-Greater than 2 cm and less than 2 cm

-Can't tell from the information given

Solution -

6. In an stabilizing selection, the average trait of a given population is favored over extreme values. Hence, it can be said that one specific trait is over presented in a given population. For example – uniform human birth weight, number of eggs a bird lay etc.  

Here in this case if most common circumference is 2 cm , then the tree population will try to have this trait as a stabilizing trait.  

Thus, option A is correct

8. In a  directional selection, the genetic variation decreases as per the environmental change. And hence the average trait will not be selected. Instead traits either higher or lower the average values will be preferred.  

Thus, option C is correct
