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.

4. A soda can has a volume of 0.35 liters and before opened its internal pressure is 30 psi. What
777dan777 [17]

The volume of the gas expansion is 0.71 liters.

<h3>Boyle's law</h3>

Boyle's law states that the volume of a given mass of a gas is inversely proportional to its pressure provided that temperature remains constant.

P₁V₁ = P₂V₂

where;

  • P₁ = 30 psi
  • V₁ = 0.35 liters
  • P₂ = 1 atm = 14.7 psi

The volume of the gas expansion is calculated as follows;

V_2 = \frac{P_1 V_1}{P_2} \\\\V_2 = \frac{30 \times 0.35}{14.7} \\\\V_2 = 0.71 \ Liters

What was the purpose of adding methotrexate to the cells expressing a genetically-engineered Dihydrofolate Reductase enzyme in t
ira [324]

Answer:

Methotrexate inhibits the synthesis of DNA, RNA, and protein synthesis of the cells in the experiment.

Explanation:

Methotrexate competitively inhibits the enzyme dihydrofolate reductase (DHFR) which is involved in the synthesis of tetrahydrofolate from the inactive dihydrofolate. The methotrexate blocks the enzyme by binding to its active site thereby preventing further reaction of the dihydrofolate reductase enzyme and dihydrofolate. Tetrahydrofolate is a useful material for the de novo synthesis of thymidine, a nucleoside. And without thymidine, DNA synthesis is hindered. Methotrexate therefore inhibits the synthesis of DNA, RNA, thymidylates and of course protein synthesis.
