Answer:

Option A, irresponsible

Explanation:

William was not intentionally "irresponsible" but due to his careless behaviour a man was killed by his car. He must have focused on the road rather than on changing the radio station. And in case if wanted to do so he must have visualized the traffic condition and then must have stopped or slow down his car before doing so. Since he continued with the same speed while changing the radio station, his car struck a man and led to his death. Thus, it is the fault of William somewhere.

The amount of water that evaporates from earth is _____.
amid [387]

Answer:

The amount of water that evaporates from earth is roughly equal to the amount that falls as precipitation.

Explanation:

In the hydrological cycle, evaporation consists of the conversion of liquid water into water vapor, which reaches the atmosphere. Once the water vapor condenses produces precipitation in the form of rain, snow or hail.

<u>On the earth the amount of water that evaporates is proportional to the water that falls as precipitation</u>. The mass of ocean water is substantially greater than the amount of land, so variations in the proportion of evaporated water and precipitation occur in the hydrological cycle:

  • <em>In the oceans, evaporation is greater than the precipitation that occurs. </em>
  • <em>On the continents - firm land - evaporation is less than precipitation. </em>

This produces a certain grade of compensation in which, globally, the amount of water that evaporates from the earth is roughly equal to the amount that falls as precipitation.

What is the optimal ph that this enzyme functions at ?
ale4655 [162]
Most enzymes' optimum pH is neutral or close to neutral, like amylase found in saliva, which has an optimal pH = 6.8. Some enzymes prefer a more drastic pH, like pepsin, which can have an optimum pH of 1.7 to 2. Sometimes enzyme pH optima depends on where the enzyme is found.

If you were working for a pharmaceutical company as part of a drug discovery team, which of these enzyme inhibitors would you su
mart [117]

Answer:

Option A, a drug to treat high blood pressure that reversibly inhibits an enzyme catalyzing production of a chemical that causes blood vessels to contract

Explanation:

The complete question is

If you were working for a pharmaceutical company as part of a drug discovery team, which of these enzyme inhibitors would you suggest as a productive avenue for drug development?

a) a drug to treat high blood pressure that reversibly inhibits an enzyme catalyzing production of a chemical that causes blood vessels to contract

b) a drug to treat diabetes that irreversibly inhibits an enzyme in the metabolic pathway to synthesize glucose

c) a compound that acts as a competitive inhibitor for a digestive enzyme produced only in the presence of certain foods

d) a compound that inhibits enzymes by significantly changing the ph throughout the body

Solution

Productive avenue of a drug simply means producing an drug that not only treats the main disease or disorder but also functions to inhibit the causative agent activity. In case of option A, both the objectives of producing drug are met and hence it is the right choice.

High blood pressure usually affects the blood vessels by narrowing them and in severe cases may rupture them. If a drug as stated in option A is produced, it will not only rectify the effects of high blood pressure but will also prevent the blood vessels from narrowing by inhibiting the activity of enzymes responsible for producing chemical that leads to blood vessel contraction.

Hence, option A is correct

Under certain circumstances, potassium ions ( K + ) in a cell will move across the cell membrane from the inside to the outside.
dexar [7]

Answer:

8.18 × 10 ⁻²¹.

Explanation:

The potential energy may be defined as the energy stored in the rest objects. This energy is important for the maintenance of the concentration gradient in the cell.

The change in the potential energy can be calculated as follows:

W = v2-v1 × q.

Here, the charge of the proton is considered because k+ ions has been used.

W= 0 - ( - 70. 5 mV) × 1.602 * 10^-19 C.

W= 8.18 × 10 ⁻²¹J.

Thus, the answer is 8.18 × 10 ⁻²¹.
