Answer:
2. Hair cells depolarize through an influx of K+, while neurons depolarize through an influx of Na+
Explanation:
The complete question is as follows :
What is an important difference between neurons and hair cells?
1. Neurons detect pressure waves, and hair cells communicate the signal to the central nervous system (CNS).
2. Hair cells depolarize through an influx of K+, while neurons depolarize through an influx of Na+.
3. Neurons release neurotransmitters, but hair cells signal using hormones.
4. Hair cells are only found in the CNS, and neurons are only found in the peripheral nervous system (PNS).
- Neurons are the cells that are electrically excitable and play a role in transmitting the nerve impulses in the body.
- Hair cells are found in the ears of the vertebrate and these are the sensory receptors of the auditory and the vestibular system.
- For the neurons, it is the influx of the sodium ions that causes the membrane potential to become more positive and cause depolarization whereas in the case of the hair cells it is the influx of potassium ions that does so.
- This reason why the K+ ions move-in is because the surrounding fluid that is the endolymph is richer in K+ ions and does the movement of the endolymph causes the K+ channels to open and K+ influx occurs in the hair cells.
The nephrons. the nephrons are composed of the glomerulus, proximal convoluted tubules, loop of Henle, distal convoluted tubules, and the collecting duct
The number of molecules in some water isn't affected by changing its temperature. But to know if you have the same number of molecules in two water samples, you need to compare their masses, not their volumes. When you heat some cool water, it expands. (When you slightly warm some ice-cold water, it contracts a little, but let's keep this simple.) So hot water takes up more space than cold water. The amount of space something takes up is called volume. If you were to have 2 cups of water, one of hot water and one of cold water with equal volumes, the cold water would have more molecules.
<span>Hot and cold water are made of the same type of molecules. Each molecule has one oxygen and two hydrogen atoms. The difference between them is the speed of the molecules jiggling around. </span>
Answer:
True
Explanation:
Outlining any information is one of the most effective techniques that lead to data processing. A person will be able to recall what a paragraph or an essay said if the main information is outlined. A person will be able to process the information from an outline and use it effectively.
In this way, all the parts which are not necessary can be overlooked and focus can be generated on the important aspects.
