Scientific inquiry is asking a question about the world and finding out an answer or explanation in order <span>to develop explanations of natural phenomena in a continuing and creative process. It is very important to follow safety rules during every scientific inquiry:
</span><span>1.Do not taste, touch, or smell substances unless directed to do so.
</span><span>2.Wear safety glasses and other required safety equipment.
</span><span>3. Keep the lab area, including table top and walkways, clear of unnecessary items.
4. </span>H<span>andle all equipment carefully and as directed.</span>
        
             
        
        
        
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.

Cellular respiration is the process responsible for converting chemical energy, and the reactants/products involved in cellular respiration are oxygen, glucose (sugar), carbon dioxide, and water. While the exact steps involved in cellular respiration may vary from species to species, all living organisms perform some type of cellular respiration. Without cellular respiration, living organisms wouldn’t be able to produce the chemical energy they need

Answer:
true
Explanation:
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
