Newton's Second Law of Motion says that acceleration happens when a force acts on a mass. Riding your bicycle is a good example of this law of motion at work.Your leg muscles pushing pushing on the pedals of your bicycle is the force. When you push on the pedals, your bicycle accelerates.

One method of bioremediation is using plants to remove arsenic and radioactive uranium from soils.
Arturiano [62]
<span>True. Plants are considered as organic materials. The process of bioremedation is a waste management technique where these organic materials are used to remove pollutants and neutralize sites that are contaminated with hazardous substances. Areas that are deemed toxic will be uncontaminated after this technique because the pollutants have been broken down by these organic substances. <span>

A team of astronomers discovers a new planet with water. They notice that there is water in lakes rivers, and oceans, but no clo
SVETLANKA909090 [29]

Which statement best explains the state of the water cycle on this newly discovered planet?

A. The water is gathered in lakes or oceans or frozen in snow and ice.

B. The water is trapped as water vapor in the atmosphere and clouds.

C. There is constant rain or snow falling on the planet's surface.

D. Water is frozen underground instead of flowing on the surface.

Complete answer:

Water is frozen underground instead of flowing on the surface. Thus, the correct option is D.

The water cycle can be broken down into three parts, as follows:

  1. Evaporation
  2. Condensation
  3. Precipitation

Evaporation: When the sun's heat drives water from oceans, lakes, streams, ice, and soils to rise into the air and transform into water vapour, this is known as evaporation (gas). Clouds form when water vapour droplets combine.

According to the first statement, water may be collected in lakes or oceans, or frozen in snow and ice. Evaporation occurs when water is collected in lakes or seas and exposed to high enough surface temperatures. Also, if water is frozen or in snow, the rate of evaporation will be significantly reduced, although it may still occur provided individual molecules carry sufficient heat. This statement provides some explanations for why we may not see evaporation, but it is not the best available to describe the water cycle on this planet.

Because of the available answers, this one best explains the state of the water cycle on this planet because it provides the most likely scenario for which astronomers would not be able to observe evaporation, given that it would occur on a small scale due to the extremely low temperatures and would take place underground, it would appear that evaporation is not working.

After drinking a great deal of coffee (pH 5), a human's blood buffering system would need to ________ as the coffee was digested
spayn [35]

Answer:

Hydrogen ion(H+)

The human blood has carbonic acid and bicarbonate anion as buffer to maintain the blood pH between 7.35 and 7.45. A virtual value higher than 7.8 and 6.8 can lead to death.

Taking coffee which has a low pH will lower the pH of the blood. In order to raise the pH back to normal and lower the level of acid present in the system. The human buffering system will to take up Hydrogen ion.
