to is when a stimulus successfully stimulates an action potential in its specific neuron. how your brain interprets the message
Xelga [282]

Information about the body and its surroundings is provided through the senses. Olfaction (smell), gustation (taste), equilibrium (balance and body posture), vision, and hearing are the five distinctive senses that only humans possess. We also have broad senses, sometimes known as somatosensation, that can react to stimuli including pressure, temperature, pain, and vibration. Somatosensation includes the sense of limb position used to monitor kinesthesia (limb movement), proprioception (the position of bones, joints, and muscles), and vestibular sensory, which is an organism's sense of spatial direction and balance. Although the sensory systems connected to these senses vary greatly, they all have the same purpose: to cause the nervous system to produce an electrical signal in response to a stimulus, such as light, sound, or body position.

<h3>What is Action potential ?</h3>

When a neuron transfers information away from the cell body and down an axon, it experiences an action potential. The action potential is also referred to as a "spike" or a "impulse" by neuroscientists. A depolarizing current causes an explosion of electrical activity known as the action potential.

Different ions crossing the neuron membrane result in action potentials. The sodium channels first open in response to a stimulus. Because the inside of the neuron is negative compared to the outside and there are much more sodium ions on the inside, sodium ions rush within the cell.

Depolarization, overshoot, and repolarization are the three phases of an action potential.

Which of the following is NOT an example of an anaerobic exercise?
nikdorinn [45]

Answer;

B. Jumping rope

Jumping rope is not an anaerobic exercise but an aerobic exercise.


Anaerobic exercise is a form of high intensity exercise that increase the oxygen debt. However since the muscles require oxygen to maintain prolonged exertion, anaerobic exercises can only last for short periods of time.

Examples of anaerobic activity sprinting, high-intensity interval training, power lifting and most athletic sports.

On the graph below, what would explain why the rabbit population levels drastically increased instead of decreasing drastically?
Ilia_Sergeevich [38]

Based on factors affecting population, the rapid increase in the rabbit population could be dues to high fertility rate, abundance of food and lack of predators.

<h3>What is population increase?</h3>

Population increase refers to the increase in the number if species of an organism found in a given habitat over time.

Increase in population can be brought about by factors such as;

  • abundance of food
  • high fertility rate
  • favorable environmental conditions
  • lack of predators

Therefore, the rapid increase in the rabbit population could be dues to high fertility rate, abundance of food and lack of predators.

How did the Miller-Urey experiment impact the way scientists think about the origins of life?
Mazyrski [523]

The Miller-Urey experiment showed that simple molecules could have arisen abiotically. This chemical experiment included conditions similar to those present on the early Earth, and tested the origin of life under those conditions.

Water (H2O), methane (CH4), ammonia (NH3) and hydrogen (H2) were the chemicals used to produce the results of the experiment, the factors needed for simple life to arise. Given similar conditions on other planets, it's possible that life could arise there as well.
