Answer:
Neither A nor B is correct
Explanation:
Hydrologic cycle is the sequence of different conditions through which the water passes from oceans to clouds, precipitates as rains, comes to the rivers and finally reaches the ocean.
This first statement in the question said that water will end up in the river which is not true because water from the river ultimately ends in the oceans because all the rivers terminate in the oceans finally.
The second statement is also wrong because when water from one ocean vaporizes and becomes cloud, it can travel large distances as clouds in the effect of wind and thus may get precipitated in the form of rain in some other part of the world. So, it is not necessary that the water will end up in the same ocean.
Answer:
It's C. In eukaryotic cells, internal membranes standardize the internal environment of all cellular organelles.
Answer:
Hunting
Explanation:
Camouflage is a hereditary physical aspect, whereas hibernation and migration are instinctual. Hunting is a learned behavior as it is not as ingrained as the other two and is not automatically done.
P.S. at first I read the answer choices to the tune of "O, christmas tree"
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.
<h2>Answer with Explanation </h2>
Cellular respiration is a process in which chemical reactions occurs that allows the body to take glucose and transform it into ATP. ATP is a more readily available form of energy for the body than glucose. Cells need energy to perform tasks, and respire to break the chemical bonds in ATP and then use it for energy. So, respiration occurs at all times in the human body, and is essential for survival.
