The best explanation for this unchecked population growth is that the predators are too few to slow down population growth of mussels. The environment limits population growth by changing birth and death rates. The factors affecting population size and growth include biotic factors such as food, disease, competitors, and predators and abiotic factors such as rainfall, floods, and temperature. Predators affect individual growth rates of surviving prey by acting to increase growth rate by thinning the density of prey populations, which releases survivors from competition.<span />
The higher biodiversity in an ecosystem means that there is a greater variety of genes and species in that ecosystem. A great variety of genes and species means that the ecosystem is better able to carry out natural processes in the face of external stress. Thus, the ecosystem is more sustainable.
The use of electronic instruments or other techniques to monitor and change subconscious activities, many of which are regulated by the autonomic nervous system, is called biofeedback.
<h3>What is biofeedback?</h3>
A mind-body approach known as biofeedback employs a variety of monitoring tools to give the body's physical functions, which are typically controlled by the body's automatic systems, conscious control. There are several kinds of biofeedback instruments that can be used to track the development of the activity and show the efficacy of the therapy as it is being administered.
The equipment that measures the following uses biofeedback the most frequently:
- brain activity
- respiration rate
- blood pressure
- heartbeat frequency and heartbeat variability
- tension in muscles
- electrification of the skin
- skin temperature
Devices used to measure body change are:
- Electromyogram (EMG): To measure muscular tension, use this.
- Electrodermal activity (EDA): This measures variations in perspiration rate.
- Measures of finger pulses: These evaluate heart rate and blood pressure.
- Electroencephalogram (EEG): This is used to assess brain electrical activity.

Answer:
D. It is a random guess about how something happened.
Explanation:
In everyday life, a theory is a hunch or a guess about how something happens (in the scientific method, we might call it a <em>hypothesis</em>).
A is <em>wrong</em>. It doesn’t necessarily explain how nature works, because it hasn’t been tested by experimental testing and observation.
B and C are <em>wrong</em>. They are features of the <em>scientific method</em>.
