Correct option is A)

There are electrical and concentration gradients in neurons that induce the sodium ions to enter the cell. The resting potential is maintained because the channels for sodium ions are closed. The membrane remains impermeable to sodium ions in the rest state. The membrane is more permeable to potassium passage. The potassium ions leak through the membrane at a greater rate than sodium enters. There is loss of positively charged ions from the inner part of the cell membrane. The inner part of the membrane carries a relatively more negative charge than the outer part of the cell membrane.

Thus, the correct answer is option A.

C.
Its C because basically when the neuron is being stimulated its excited like in gas where the the atoms are super hyper. On the other hand in things like ice the atoms are not moving at all but they have the potential to moving making the right choice C

Answer:

Deposition

Explanation:

Landslides occur under the effect of gravity. When a mass of rock or earth slides down from a mountain or from a cliff then this phenomenon is termed as Landslide.

Landslides are considered to be a rapid method of erosion. Wind, waves, running water, glaciers and gravity are the five agents of erosion out of which the gravity influences the process of Landslides.

Landslides occur suddenly and are dangerous example of the movement of earth materials under the influence of gravity. When weathered material falls away from a cliff, it slides down under the effect of gravity and finally after reaching the hill, the material gets deposited there. This is called Deposition by landslides.

A lamp that plugs into a wall socket draws energy which flows through a thin wire in the bulb causing it to glow. What energy tr

Softa [21]

Answer:

Electrical>thermal>light

Explanation:

Electrical energy refers to energy which is gotten from potential energy. This energy source could be a wall socket.

Thermal energy on the other hand refers to internal energy of a system where temperature is constant.

Light energy is made up of photons which transmits electromagnetic radiation which move in waves and become visible to human eye.

Therefore, the energy transformation taking place according to the question is option D.

A desirable intake of dietary fiber is _____ grams daily, according to the american dietetic association.

vovikov84 [41]

Answer:

A desirable intake of dietary fiber is 20-35 grams daily, according to the American Dietetic Association.

Explanation:

Dietary fiber has always been a part of a healthy, balanced eating lifestyle. Fiber has 2 types, soluble and insoluble. Soluble fiber is a gelatin-like substance when combined with water and when ingested, can help slow the travel of food in the gut, making you feel "full." Insoluble fiber or roughage is the bulk-forming type. It holds water in its structure, helping regulate the bowel movements.

Fiber, being a complex carbohydrate, can help lessen the risk of an increase of bad cholesterol and blood sugar. Examples of fiber-rich foods are whole grain products, barley, oats, grapes, etc.

What are four characteristics of a good extraction solvent?

ella [17]

A good extraction solvent should have a strong solubilizing capability for the compound of interest, it should be immiscible or only weakly misciblewith the matrix solvent ( the first solution or mixture containing the compound from its natural source, e.g., water/ether. water/ chloroform, etc. If possible the extraction solvent should be non-flammable, non-toxic or of low toxicity, reasonably volatile, and of low eco-impact. Inexpensive and available, of high purity , and shelf stable. If one is determining the compound of interest by UV/Vis spectrophotometry or fluorescence, the solvent should have extremely low absobance or emission at the wavelength of analysis

• high solubility for the solute and low solubility for the carrier liquid.

• density difference vs. the carrier liquid greater than 150 kg/m. ...

• mid-level interfacial tension (5–30 dyne/cm)

• high resistance to thermal degradation.
