Answer:
Enzymes help speed up chemical reactions in the human body. They bind to molecules and alter them in specific ways. They are essential for respiration, digesting food, muscle and nerve function, among thousands of other roles.
Answer:
Explanation:
1. Depolarizes (depolarization of membrane causes opening of sodium channels which causes outward motion of emphatically charged sodium particles into the grid from the phones. This makes the network be profoundly positive charged and the cell film turns out to be exceptionally contrarily charged)
2. Sodium particles, ECF (As the layer depolarizes, the voltage gated sodium channels situated over the plasma membrane open up and the outwards motion of sodium particle happens deserting an enormous negative charge on plasma layer)
3. Invigorated (the muscle cells contain afferent and efferent neurons which help in transfer of data from muscles to mind and back to muscles. This progression of data happens by the methods for emission of synapses from the mind because of an upgrade)
4. Potassium particles, hyperpolarize (after the activity potential has been played out, the sodium particle channels near forestall further spillage of sodium particles in the ECF. Be that as it may, the potassium channels stay opened for longer occasions and consequently hyperpolarize the layer with a net profoundly negative charge)
5. Resting membrane potential (this procedure is known as transmission of motivation in a cell by a pattern of polarization, depolarization and hyperpolazation)
To copy the DNA, recombinant DNA method use bacteria such as E. Coli whose plasmids has been combined with various gene to produce the substance that is wanted.
Answer:
The correct option is <u>C. The nervous system when the brain regulates the body's breathing and heart rate.</u>
Explanation:
The main function of the respiratory system is to exchange oxygen for carbon dioxide in the body.
The brain controls the rate at which the heart pumps blood. The pumping of the heart supplies oxygenated blood to other parts of the body. Hence, the rate at which heart pumps blood is very important to maintain homeostasis of the respiratory system.
The brain regulates the rate at which a person breathes. This rate is very important to breathe in the right amount of oxygen and to breathe out the right amount of carbon dioxide.
