Why are multiple action potentials generated in response to a long stimulus that is above threshold?

1 answer:

5 0

Solution: The rapid rise and fall in the membrane potential across a cell's membrane is known as action potential. The generation of the action potential is necessary for the transfer of the nerve impulses across the neurons. The nerve impulses are generated only when the cell membrane is depolarized to its threshold level. These potentials are generate din response to different stimuli. When this stimulus is long, the recovery time is increased and the action potentials are allowed to occur after the relative refractory period above the threshold. (A refractory period can be defined as the time during which no action potential can be generated.)

This causes the generation of the multiple action potentials.

The correct answer is A.
Oswald Avery applied several biochemical techniques to large cultures of bacteria in order to extract and purify the "transforming principle". Their experiments showed that most probably the "transforming principle" was DNA. One of the observations leading to this conclusion was that enzymes that degrade proteins or RNA (such ribonucleases) had no effect on the "transforming principle". On the contrary, enzymes degrading the DNA destroyed the extract's transforming capacity.

Answer:

C. Can be replenished by nature in a short period of time

Explanation:

Renewable, as a word, means that it is able to be replaced again. Renewable energy is energy that is able to be replaced quickly, and will never run out. Solar, biomass, geothermal, wind, and hydropower energy all can be reproduced again without the risk of running out, unlike fossil fuels.

Hope this helps!

How do airplanes stay in the air?

victus00 [196]

Answer:A plane's engines are designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane's weight and holds it in the sky. ... The wings force the air downward and that pushes the plane upward.

The world has the least amount of oil as for fuel. All oil traps contains an impermeable layer but a permeable rock that contains hydrocarbon fluids and gases is called a(n) oil reservoir. Whereas syncline is least likely to contain an oil trap. In U.S oil production is less than oil consumption.
