Answer:
of blood plasma was “cleared”
Explanation:
Given,
Concentration of a person’s blood cortisol
µg/mL
The amount of cortisol excreted from the body in a period of 24 hour
mg
The volume of blood plasma cleared during this time period is equal to
amount of cortisol excreted from the body divided by Concentration of a person’s blood cortisol
The above definition could be represented as following-
volume of blood plasma cleared 
Where A represents amount of cortisol excreted from the body
while B represents the concentration of a person’s blood cortisol
Substituting the given values in above equation, we get -

of blood plasma was “cleared”
Answer:
Increased keystone species
Explanation:
An organism is a keystone species when it contributes to the definition of a given ecosystem such that the absence of the keystone species in an ecosystem, the ecosystem will change dramatically or be gradually wiped out
