<h2>Sodium channels </h2>
Explanation:
Depolarization is a result of sodium channels opening as a result of chemical or pressure-based stimuli
- Depolarization starts when a threshold stimulus applied on a neuron via Na+ mechanically operated channels that trigger action potential
- Action potential is an efficient signaling process by which distantly located cells communicate to each other
- Depolarization of membrane potential is due to influx of Na+ via voltage gated Na+ channels
- Fast opening of voltage gated Na+ channel shifts membrane potential from -70mV to + 50mV at which voltage gated Na+ channels become inactive thus influx of Na+ abruptly stops
Answer:
5' --> 3'
Explanation:
New nucleotides are added to the hydroxide group on the ribose sugar side. That is the 3' side.
Answer:
all of the above
Explanation:
Water biomes describe all the living things living in an area of water such as a lake or ocean. The surrounding environment plays a huge part in what organisms able to live there.
For example, green plants and algae require sufficient sunlight and oxygen to perform photosynthesis. Green plants and algae are an important food source for many other organisms. The amount of salt is important for various fish, as they will be unable to survive in very high salt concentrations. Therefore, all of the above are limiting factors.

Hope I helped, would love if you left me a thanks! Thanks :)
Let's go through the choices!
A. They're unaffected by positive self-talk.
Let's pretend you are scared of thunder. If you tell yourself, "I will not let thunder scare me; it will not hurt me," you will be less scared! So, A is not the answer.
B. They're harmless, because they're imaginary.
If you are scared of something, it can damage your mental health, which is not harmless. So, B is not the answer.
C. They're a kind of negative self-talk.
Being afraid of something is usually due to an overexaggeration in your mind. So, C is a good answer.
D. They're a kind of positive reinforcement.
Being scared is not positive. So, D is not the answer.
The answer is C!
Hope I helped! :)
