Answer:

The mass of the cube would increase if the water moved into the potato cube or the mass of the potato cube would decrease if the water moved out of the potato cube after placing it in the beaker.

Osmosis can be described as a process by which water moves from an area of higher concentration to an area of lower concentration along the concentration gradient. It is a type of passive transport.

If the potato cube is placed in water, most likely the water will enter into the cell as the concentration of solutes will be more in the potato cube and the concentration of water will be less. Hence, the mass of the potato cube would increase.

The semilunar valves of the heart open at the onset of the ejection period. Approximately what percentage of the stroke volume i
mr Goodwill [35]

The percentage of the stroke volume is ejected during the first quarter of systole will be approximately 60% to 65%

<u>Explanation:</u>

The time interval between the atria contraction and the relaxation of ventricles are called as a Cardiac cycle. Systole denotes the heart contraction during the blood pumping. Diastole refers to the heart relaxation when the blood is filled in the heart chambers. The total blood is not fully pumped by the ventricles.

Instead they will pump only a proportion of blood in each of the cardiac cycle.  The ejection fraction refers to the proportion of the intraventricular volume that is received as a output in circulation process. A human with normal heart functioning can have approximately 60-65%. This is known to be stroke volume. The blood volume that is ejected is strove volume.

liubo4ka [24]

The correct answer is that the following is true concerning sources of water pollution is option a. Mine wastes and heavy metals become water pollution through stormwater runoff.

Mine wastes and heavy metals become water pollution through stormwater runoff. As water contaminates by producing coppers, sulfate, sodium as the toxic elements contaminating the water. The chemicals are released from mining activities by contaminating soil, air, by causing pollution.

<h3>What are sources of water pollution?</h3>

The sources of water pollution are :

  • mining
  • industrial wastes.
  • marine dumping
  • burning of fossils
  • chemical fertilizers.

Hence concluded that water pollution can cause be caused by  Mine wastes and heavy metals becoming water pollution through stormwater runoff.
