Answer:
The inward flow of sodium ions increases the concentration of positively charged cations in the cell and causes depolarization, where the potential of the cell is higher than the cell's resting potential. The sodium channels close at the peak of the action potential, while potassium continues to leave the cell.

True
Explanation:
If the net force on an object at rest is zero, the object will remain at rest. This is one of the postulates of newton's law of motion.
Newton's first law of motion states that "an object will continue in its state of rest or uniform motion unless if it is acted upon by an external force. "
- If no net force acts on a body, it will forever remain at rest.
- The force on a body causes its motion and acceleration.
- A body will continue in uniform motion if no external force acts on it.

Answer:
what differences do you observe in the syringe or its contents before the air was pumping into the syringe and after?
Explanation:
When an air bubble enters a vein, it's called a venous air embolism. When an air bubble enters an artery, it's called an arterial air embolism. These air bubbles can travel to your brain, heart, or lungs and cause a heart attack, stroke, or respiratory failure.You can compress it, or squeeze it into a smaller volume. When you push on the plunger you can feel the air pushing back. When you stop pushing, the air inside the syringe will return to its original size.
Answer: studies indicate that humans living in warm, tropical environments (from a variety of populations) tend to have noses that are wider at the base because inhaling warm, moist air does not require adaptations.
Explanation:
Sensory neuron(s) then transmit information from the sensory receptor(s) to the Central Nervous System
Explanation:
These receptors are located all over the body but some types of receptors are in specific areas of the body (e.g. taste receptors in the mouth).
Sensory neuron(s) then transmit information from the sensory receptor(s) to the Central Nervous System (i.e. the brain and spinal cord, sometimes referred to in the abbreviated form: C.N.S.). This is happens because peripheral nerves all connect to the spinal cord via the network of nerves within the nervous system.
The information so received by the C.N.S. is further transmitted by relay neurone(s) with the C.N.S.
