object slows down), the way in which we calculate a drag force will be slightly different. .and “coefficient of drag , is it easy for objects to move through it
Explanation:
Answer:
The charges inside and outside of the neuron before receiving a stimulus are negative and positive, respectively, which corresponds to the transmembrane rest potential.
Explanation:
Neuron is the specialized cell of the nervous system in charge of transmitting electrical impulses. The generation of a nerve impulse in the form of an electric current is due to a change in the transmembrane potential.
<u>Outside the neuron cell, electrical charges are predominantly positive, and the ion with the highest concentration is sodium. In the intracellular space, a great quantity of proteins provide negative charge, and there is a predominance of potassium ions</u>. Under these conditions, the ionic channels are closed.
For this reason, a neuron at rest, before receiving a stimulus, presents positive charges on the outside and negative charges on the inside, and the membrane potential in this condition is estimated at a value of -65 mV.
Once a stimulus is produced, the ionic channels open and Na+ ions enter the cytoplasm, exchanging them for K+, which implies a change in the membrane potential which, on reaching the threshold, produces an action potential and the nerve impulse is produced.
Answer:
<h2>a. 1000 X 2^8</h2>
Explanation:
As given;
Initial population of bacteria= 1000;
Log phase growth is exponential phase, period in which bacteria gets double.
Generation time= 15 minutes;
it means, bacteria get double in every 15 minute,
so after 2 hours, bacteria will have 8 generation times;
so the final generation of bacteria is =1000 X 2^8.
Final bacterial generation after two hours = 256,000(1000 X 2^8)
