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.

B. Other enzymes in the small intestine further break the potysaccharide into monosaccharides.

C. You take a bite and to chew the complex carbohydrate into smaller pieces.

The correct order are,

C. You take a bite and to chew the complex carbohydrate into smaller pieces.

A.The enzyme, amylase. which is present in saliva breaks potysaccharide chains into disaccharides.

D.Amylase is deactivated by the low pH in the stomach.

B. Other enzymes in the small intestine further break the potysaccharide into monosaccharides

.E. Monosaccharides are absorbed through the intestinal wad

Explanation:

Carbohydrates are complex or large molecules are they are found in rice, bread e.t.c

Digestion of carbohydrates start from the mouth through a process called mastication i.e chewing of the carbohydrates. The salivary gland then secrete the salivary amylase which act on the chewed carbohydrates. The salivary amylase breaks down amylose and amylopectin present in starches into smaller chains of glucose which is called dextrins and maltose. When it get to the stomach, the amylase cannot further break it because it does not work in acidic conditions. The substance form chyme in the upper stomach and pancreatic enzymes act on it to break it down into simple sugar glucose. The pancreatic enzymes include sucrase, maltase and lactase.

Sucrase breakdown sucrose into glucose and fructose, maltase breakdown maltose in two molecules of glucose and lactase breakdown lactose into galactose and glucose. The simple sugar are then absorbed into the blood through the intestinal wall.

What happens to ADP after ATP hydrolysis?
kotegsom [21]

Answer:

ADP is combined with a phosphate to form ATP in tADP+Pi+free energy→ATP+H2O

Explanation:

The energy released from the hydrolysis of ATP into ADP is used to perform cellular work, usually by coupling the exergonic reaction of ATP hydrolysis with endergonic reactions.

1) The process arrow A represents is photosynthesis.

2) Arrow A represents light energy transformation. Light energy from the sun is converted into chemical energy in plants.

3) Photosynthesis is part of a carbon recycling process in the carbon cycle. Plants absorb light energy and convert it to chemical energy. Plants absorb carbon dioxide which is exhaled by humans and animals. Plants then produce oxygen which is absorbed by humans and animals. Animals also eat plants thus passing the carbon compounds along.

I hope this makes sense. Hope this helps! :)

Abnormally slow depolarization of the ventricles would most likely change the shape of the ________ in an ecg tracing.
Leni [432]
Abnormally the slow depolarization of the ventricles would most likely change the shape of the QRS in an ECG tracing. It is a combination of three graphical deflections which is seen on a typical electrocardiogram. It is the most visually obvious and central part of the tracing. It corresponds to depolarization of left and right ventricles of the human heart.
During the activity, it may be shorter in children.
QRS waves occur in succession rapidly. Q wave is a downward deflection following P wave. R wave follows upward deflection and S wave is downward deflection which is after R wave while T wave follows S waves.
