Answer:
C
Explanation:
For electromagnetic waves frequency X wavelength = speed of light
f * 2.2 x 10^-11 = 3 x 10^8 m/s
f = 3 x 10^8 / 2.2 x 10^-11
= 1.36 x 10 ^19
= 1.4 x 10^19 with two significant digits
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

carbon fluoride is the answers
This is the chemical doula for salt which is a polyatomic anion very prevalent in out daily lives e.g.
Salts, acid derivatives, and peroxides of sulfate are widely used in industry.
The answer for the given question above is IONIC. <span>Ionic substances form giant ionic </span>lattices<span> containing oppositely charged ions. They have high melting and boiling points, and </span>conduct<span> electricity when melted or dissolved in water.</span>
