B. Removal of topsoil to reach water supply
C. Transportation of coal via waterways
D. Use of machinery underground to mine coal

Answers

Answer:

A. Large amounts of water force open cracks in rocks

Explanation:

Hydraulic fracturing, or fracking, is a drilling method used to extract petroleum (oil) or natural gas from deep in the Earth. In the fracking process, cracks in and below the Earth's surface are opened and widened by injecting water, chemicals, and sand at high pressure.

A is basically explaining this the same way. Forcing cracks in the ground with liquids.

How is sucrose produced from the end products of photosynthesis?

Answers

Sucrose is the end product of photosynthesis and the primary sugar transported in the phloem of most plants. ... SuSy catalyzes the reversible cleavage of sucrose into fructose and either uridine diphosphate glucose (UDP-G) or adenosine diphosphate glucose (ADP-G).

Sucrose is produced from the end products of photosynthesis by the fact that when oxygen is liberated in the atmosphere and hydrogen facilitates the assimilation of carbon dioxide in the dark reaction, which ultimately forms sucrose, starch, and maltose.

What is Photosynthesis?

Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.

Calvin cycle stimulates the synthesis of Sucrose. In the cytosol, triose phosphate gest converted into Fructose 1, 6- bisphosphate which ultimately forms Glucose 1- phosphate that leads to the formation of UDP Glucose and ultimate sucrose if formed.

Therefore, the process of formation of sucrose from the end products of photosynthesis is well described above.

Which statements about wells are true? Check all that apply.

Wells bring groundwater from the unsaturated zone to the surface of the water.
Wells need to be drilled below the water table.
If water is pumped from a well too quickly, the well may run dry.
Water from wells is generally not safe to drink.
Water gushes from artesian wells due to pressure.

Answers

Answer:

Wells need to be drilled below the water table.

If water is pumped from a well too quickly, the well may run dry.

Water gushes from artesian wells due to pressure.

Explanation:

The statements that assert a true claim regarding the wells would be as follows:

b). Wells need to be drilled below the water table.

c). If water is pumped from a well too quickly, the well may run dry.

e). Water gushes from artesian wells due to pressure.

The above statements offer appropriate claims regarding the wells that they are required to be penetrated down the water table because it assists in striking the water from the lower levels as well. The next statement asserts that water must be transported from wells in a hurry because it can impact the yielding ability of the wells.The streaming of water from the artesian wells is primarily because of the pressure as it helps in the release of the water effectively.

Thus, options b, c, and e are the correct answers.

i think that the higher the body temperature the higher the cellular respiration

Explanation:

The graph indicates the relationship between body temperature and cellular respiration. As the body temperature increases, more ATP is produced, but after a certain temperature, there is no cellular respiration.

What is cellular respiration?

In cellular respiration, the cell breaks down glucose and forms ATP. Glucose is broken down by glycolysis, the Krebs cycle, the electron transport chain, and finally ATP is formed.

In the graph, it is shown that an increase in body temperature is related to an increase in ATP molecule production. ATP molecule production is nearly zero at 80 degrees body temperature. As the temperature increases to 100 degrees, ATP production increases to nearly 50.

After 100 degrees, the body temperature rises, but there is a decrease in ATP production. After 100 degrees, the enzymes required for cellular respiration don't work. Hence, a decline in ATP is seen.

Hence, after a certain temperature, the enzymes involved in cellular respiration don't function as their structure changes.

6. Why can't water be used to dissolve the
caffeine found in coffee and tea?

Answers

Caffeine or supercritical carbon dioxide is a less polar compoundWater is highly polar solvent.So water can't dissolve caffeine much.

Alcohol is used to extract caffeine

Tea's chief component is cellulose, which is not soluble in water. Caffeine is water soluble, but so are tannins and gallic acid, which have been established during the heating process of tea leaves. The latter two components can be converted to insoluble in water calcium salts.

What is solubility?

The maximum amount of a substance that will dissolve in a given amount of solvent at a given temperature is defined as solubility.

Solubility is a property of a specific solute-solvent combination, and the solubilities of different substances vary greatly.

It is one of the critical parameters for achieving the desired drug concentration in systemic circulation for the desired (anticipated) pharmacological response.

Caffeine is more soluble in nonpolar methylene chloride than in water, so it will migrate to the methylene chloride layer (known as the organic layer). Because the organic layer is denser than water, it will be at the bottom.

Thus, water can not be used to dissolve the caffeine found in coffee and tea.
