<span> If the concentration of blood is 0.5 M, and red blood cells that are bathed in blood neither shrink nor swell and burst, the concentration of cytoplasm of RBCs is A. 0.5m. An isotonic solution refers to two solutions that have the same water concentration on both sides of a membrane. So, cells in isotonic solution have the same water concentration as the isotonic solution and thus they will neither shrink nor swell and burst. If the concentration of blood is 0.5 M, the concentration of RBC cytoplasm must be the same (0.5 M).</span>

Answer:

The answer is 6.4 × 10^{-20} Joules

Explanation:

This question wants to effectively test your knowledge of the names of the negative powers of 10, so first of all, before calculating, let me explain what each of the symbols in the units given in the question means:

Force = 8.0 pN = 8.0 × 10^{-12} N

displacement = 8.0 nm = 8.0 × 10^{-9} N

Now let us calculate the work.

work = Force × Displacement

work = 8.0 × 10^{-12}  × 8.0 × 10^{-9} = 64 × 10^{-21}

= 6.4 × 10^{20} Joules (in standard form)

In the northern hemisphere, winds associated with a low-pressure system system blow ___. ?
Lelu [443]
<h3><u>Answer;</u></h3>

A. counterclockwise toward the center

<h3><u>Explanation;</u></h3>
  • <em><u>In the Northern Hemisphere, winds associated with a low-pressure system blow in a counterclockwise direction towards the center, while those that are associated with a high-pressure system blow in clockwise direction outwards from the center.</u></em>
  • In the Southern Hemisphere on the other hand, winds that are associated with a low-pressure system blow clockwise towards the center.
  • <em><u>The rotation of the earth creates a force called the Coriolis force, which gives the wind that is within high pressure systems a clockwise circulation in the northern hemispheres and a counterclockwise circulation in the southern hemisphere.</u></em>

Alika [10]

Answer;

b. nitroglycerin may give incomplete or no relief of myocardial infarction pain.


Two conditions related to cardiac compromise are angina pectoris and myocardial infarction. In comparing the​ two, remember​ that nitroglycerin may give incomplete or no relief of myocardial infarction pain.


Explanation;

-Angina pectoris is the chest pain or discomfort due to coronary heart disease. It occurs when the heart does not get enough blood, due to blockage or narrowing of one or more heart's arteries.

-Myocardial infarction occurs when there is decreased blood flow or stoppage to a part of the heart, resulting to the heart muscle damage.

-Nitroglycerin extended-release capsules are used to prevent chest pain (angina) in people with a cardiac compromise. However, Nitroglycerin may give incomplete or no relief of myocardial infarction pain.
