Answer:

Placing salty water in  A and distilled water in  B.

Explanation:

The fastest net rate of water movement into the A-side will occur if we place salty water on that side and distilled water in the other one. The reason for this is that the A-side contains a higher concentration of solute than B. So, the water will pass the semipermeable membrane and go to the A-side to valance the concentrations on both sides. As we can see, there is an increase in the net rate of water movement into A.

Explain how the terms atom, compounds, element, and molecules all relate to one another
Alex777 [14]
For starters, atoms are the basic building blocks of matter- they make up elements, molecules and compounds. Elements most often combine with other elements as compounds. Whilst molecules are particles found in both elements and compounds. I hope that wasn't too confusing, but bottom line is that they are all linked together in this way! Helpful? :)

How does the process of dissolving occur​
andrew11 [14]
Dissolving is when the solute breaks up from a larger crystal of molecules into much smaller groups or individual molecules. This break up is caused by coming into contact with the solvent. In the case of salt water, the water molecules break off salt molecules from the larger crystal lattice.

Effectus [21]

Answer:

The correct answers are:

1. closing

2. the ventricles and arteries,

3. a constricted trachea

Lub is the first sound of a heartbeat and is mentioned as S1. It is usually produced due to the closing of tricuspid and and mitral or bicuspid valves present between atria and ventricles.

Tricupsid is located between atrium and ventricle of the right hand side and mitral valve is located between atrium and ventricle of the left hand side. They prevent the back flow of blood from ventricles to their respective atria.

Dub, being the second sound is written as S2. It is produced due to the closing of pulmonary (located between right ventricle and pulmonary artery) and aortic valves (located between left artery and aorta).

These valves prevent the back flow of blood from arteries into the ventricles.

The time between the two sounds is often taken as the measure of the diastole i.e. ventricular filling.

Wheezing refers to a high-pitched sound produced when a person breathes, especially during exhale. It is caused by constriction of the airways or inflammation. It is considered as a symptom of various diseases such as asthma, COPD, allergies, bronchitis etc.
