Oil is non-renewable, the rest are renewable
Answer:
The correct answer is C and Engelmann conducted this experiment to prove relationship between algae and the rate of photosynthesis.
Explanation: First we must talk about 3 facts:
1) Prism scatters the white light into different wavelengths.
2) Photosynthesis, 6 carbon dioxide and 6 water molecules are consumed and 6 oxygen and 1 sugar molecule is synthesized using light energy.
6CO2 + 6H2O → C6H12O6 + 6O2
3) Aerobic bacteria breaks down sugar while using oxygen and produces water and carbon dioxide in simplified terms.
So with this experimental setup a researcher can understand the rate of the photosynthesis by increased accumulation of aerobic bacteria near algae in certain wavelengths since they uses oxygen and tend to move close to the oxygen source (<u>see figure</u>). In this experiment there are no ways to measure heat (B), there is no known relation between wavelength of light and aerobic respiration since it can happen even in the dark (A) and finally there are no ways to measure carbon dioxide (D).
Answer:

Explanation:
Research studies results.
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.
