Based on ecological studies, the definitions below applies to the given terms:

  • Peak phenomena: this is when a population grows at a fast rate, then quickly drops when the resources run out
  • Biological surplus: this occurs when there are more organisms in a population than the ecosystem can sustain
  • Climax community: this is a point in an ecosystem when all populations reach a point of little or no change
  • Sigmoid phenomena: this is when a population increases while food and habitat are abundant and decreases as food becomes less available

<h3>What is ecology and what are some terms in ecology?</h3>

Ecology is the study of living things and their interactions with their environment.

Some terms in ecology include:

  • Peak phenomena: this is when a population grows at a fast rate, then quickly drops when the resources run out
  • Biological surplus: this occurs when there are more organisms in a population than the ecosystem can sustain
  • Climax community: this is a point in an ecosystem when all populations reach a point of little or no change
  • Sigmoid phenomena: this is when a population increases while food and habitat are abundant and decreases as food becomes less available

The concentration of the stock solution she needs is 100 milli molar (mm) and she needs to make 1.2 milli liters (ml) solution o
Lera25 [3.4K]
Molarity is defined as the number of moles of solute in 1 L of solution 
molarity of stock solution to be prepared - 100 x 10⁻³ mol/L
volume of stock solution to be prepared - 1.2 mL 
Therefore number of moles in 1.2 mL - 100 x 10⁻³ mol/L x 1.2 x 10⁻³ L 
number of moles of drug - 1.2 x 10⁻⁴ mol 
mass of drug required - 1.2 x 10⁻⁴ mol x 181.6 g/mol = 21. 8 mg
21.8 g of drug is required to make the stock solution
