Correct answer: D). Soil is made from rock and organic material.

The soil is defined as the loose sediment, it is the end result of rock weathering. It is formed by the combination of weathered rock along with the organic material that is known to support the plant growth. It is made up of clay, silt, sand, and dead and decayed organic material. Water and air are the other ingredients that are present in the soil.

Hence, the correct answer would be option D.

How does your stomach tell your brain its hungry?
iVinArrow [24]
<span>There are two hormones that determine whether you fell hungry or full -- ghrelin and leptin. Ghrelin sounds like gremlin, and it's the hormone that makes your stomach churn and says, 'Hey, you gotta eat.' The second, leptin, sends message from fat that tells your brain you are full.</span>

aivan3 [116]

When the nurse has observed of a patient who runs a ventricular tachycardia, it would likely show that their no presence of P waves, there is a wide QRS complex in the monitor and the rate would range between 100 to 250, if all manifest this in the monitor, it is likely that the patient has ventricular tachycardia. The medication that the nurse should give to the client who has exhibit this should have an anti-dysrhythmic drugs, that is important in the first line of treatment. Drugs of these kind include, lidocaine, procainamide and even amiodarone. If there is a need to correct the rhythm, it is likely that cardioversion is given as a treatment.

Ears

¿Qué es el oído y qué hace?

El oído consta de tres partes diferentes, que funcionan conjuntamente para captar sonidos y transmitírselos al cerebro: el oído externo, el oído medio y el oído interno.

El oído externo

El oído externo está formado por el pabellón auditivo (también conocido como "pabellón auricular" o "pabellón de la oreja") y el conducto auditivo. Los pabellones auditivos son las partes visibles que tenemos a ambos lados de la cabeza y están compuestos por cartílago duro cubierto de piel. La principal función del pabellón auditivo consiste en captar sonidos y conducirlos hacia el conducto auditivo, que conecta con el oído medio. Las glándulas de la piel que recubren el interior del conducto auditivo fabrican cera o cerumen, que protege este conducto, eliminado la suciedad y ayudando a prevenir posibles infecciones.

El oído medio

El oído medio es una cavidad llena de aire que transforma las ondas sonoras en vibraciones y las transmite al oído interno. El oído medio está separado del externo por el tímpano (o membrana timpánica), una fina lámina de tejido que va de lado a lado del conducto auditivo y que está fuertemente tensada sobre él. Los sonidos golpean el tímpano, haciendo que se mueva.

Can someone help me with these questions?
alexira [117]

Answer:

1.32°F

2.212°F

Explanation:

1.The melting point is the temperature at which a solid turns to a liquid. The melting point at which ice — a solid — turns to water — a liquid — is 32°F (0°C).

2.Water boils at 212°F at sea level, but only at sea level. Changes in atmospheric pressure will alter the temperature at which water boils. To use this calculator you will need your current pressure and elevation.

3.In other words, the water molecules within ice move faster. However, temperature doesn't change as heat is added during a phase change; for example, when the ice melts. During the phase change, the added heat doesn't make the molecules move faster, but rather further apart.
