B. Green
Chlorophyll is found in and around the photosystems embedded in the thylakoid membrane of the chloroplasts.
The chloroplasts are organelles found in eukaryotic algae. The chloroplasts in eukaryotic celss are contained in the cytoplasm together with other organelles.
<span>Since the chlorophyll is insided the chloroplast which is inside the cytoplasm, it is safe to say that the chlorophyll of the green algae is spread throughout the cytoplasm of its cells.</span>
Answer:
What are the three species?
Answer:
9.23×10^-4
Explanation:
Move the decimal point to make 0.000923 a new number between 1 and 10. Because our original number is less than one, we move the decimal point to the right. Drop any zeros in front of the number. Keep track of how many times you move the decimal point
and is always going to be the number you co.e up with ×10 and how many times you moved the point left or right
right= +
left= -
The reduced potential causes hundreds of <u>voltage-gated sodium</u> channels to open on that part of the cell membrane. The depolarization of the cell causes more of <u>voltage-gated sodium </u>channels to open in adjacent parts of the cell membrane. This begins the wave of of <u>depolarization</u> moving down the axon. Depolarization begins at the <u>axon hillock.</u>
Explanation:
When there is no neuron signaling it becomes polarized, termed as resting membrane potential (RMP) at a threshold voltage (around -55 mV), due to the action of the sodium-potassium pump and the potassium leak channels.
When a change in the RMP occurs, depolarization takes place which causes the voltage-gated sodium channels to open and sodium ions rush into the nerve cell which in turn will increase the voltage threshold to nearly around +40 mV and also charges the neuron positive. This depolarization moves down the axon. This increase in threshold stops the sodium influx and opens the potassium channels to rush the potassium out of the cell.
All these actions decrease the membrane potential leading to a wave of depolarization and going back to resting state. Depolarization begins depending upon the potential gradient at the axon hillock.
