Why does DNA need to replicate before cells divide?
Nonamiya [84]

Answer:

Below:

Explanation:

Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell. ... Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.

The use of electronic instruments or other techniques to monitor and change subconscious activities, many of which are regulated
Wewaii [24]

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:

  1. Electromyogram (EMG): To measure muscular tension, use this.
  2. Electrodermal activity (EDA): This measures variations in perspiration rate.
  3. Measures of finger pulses: These evaluate heart rate and blood pressure.
  4. Electroencephalogram (EEG): This is used to assess brain electrical activity.
