Answer:
water polarity causes cohesion that pulls other water molecules up through a plant.
Explanation:
Water for plants is essential because it constitutes one of the necessary elements so that they can generate their food through the process called photosynthesis.
In effect, plants take the hydrogen from a water molecule and discard the oxygen, providing the atmosphere with this essential gas for life.
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.
Answer:
Carbohydrates are used by the body for energy and structural support in cell walls of plants and exoskeletons of insects and crustaceans. They are made of smaller subunits called monosaccharides. Monosaccharides have <u>carbon</u>, <u>hydrogen</u>, and <u>oxygen</u> in a 1:2:1 ratio.
Difinition of disaccharides: any of a class of sugars whose molecules contain two monosaccharide residues.
Make an example...
Short carbohydrate chains are called <u>oligosaccharides</u> and contain 3 to 10 sugar molecules. Long carbohydrate chains can contain hundreds or even thousands of monosaccharide units. molecule of <u>glucose</u> and one molecule of <u>fructose</u> joined together.
