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

Answer:
D. TTACGCCAGG. that would be your answer.
Answer:
Density, melting point. and magnetic properties
Explanation:
I can think of three ways.
1. Density
The density of Cu₂S is 5.6 g/cm³; that of CuS is 4.76 g/cm³.
It should be possible to distinguish these even with high school equipment.
2. Melting point
Cu₂S melts at 1130 °C (yellowish-red); CuS decomposes at 500 °C (faint red).
A Bunsen burner can easily reach these temperatures.
3. Magnetic properties
You can use a Gouy balance to measure the magnetic susceptibilities.
In Cu₂S the Cu⁺ ion has a d¹⁰ electron configuration, so all the electrons are paired and the solid is diamagnetic.
In CuS the Cu²⁺ ion has a d⁹ electron configuration, so all there is an unpaired electron and the solid is paramagnetic.
A sample of Cu₂S will be repelled by the magnetic field and show a decrease in weight.
A sample of CuS will be attracted by the magnetic field and show an increase in weight.
In the picture below, you can see the sample partially suspended between the poles of an electromagnet.
Argon monatomic in nature because it is a noble gas and has completely filled shells and thus does not form a bond with other elements.
Number 4 is
-Oxidation occurs at the anode, while reduction occurs at the cathode. Recharging a battery involves the conversion of electrical energy to chemical energy. During recharging, there is movement of electrons from an external power source to the anode, and on the other side electrons are removed from the cathode.
