Do you think osmosis occurs when a cell is in an isotonic solution explain your reasoning
Bumek [7]
The word isotonic is used to refer to the solutions (two solutions) which have the same osmotic pressure in both sides of the semipermiable membrane. The condition allows the free movement of water across the membrane. However, this does not change the concentration of the solution across the membrane. 

Hence, osmosis may not occur in this condition.

Which phrases describe air pressure? Select three options.
9966 [12]
  • decreases as altitude increases
  • results from a column of air pushing on an area
  • decreases due to fewer air particles pushing down

Pressure is the force exerted, by a substance, per unit area.

Explanation:

Pressure is given by the formulae;

P = F/ A

Whereby;

P = pressure

F = Force

A = area

Remember that ..

F = Ma

Whereby;

F = Force

M = mass

a = acceleration

Therefore pressure can be given as;

P = Ma / A

The mass of the above column of a substance multiplied by the acceleration due to gravity = pressure exerted by the substance.

Which substance is a compound? <br> salt <br> phosphorus <br> sulfur <br> oxygen
tankabanditka [31]

Answer: The correct answer is salt.

A compound is a chemical substance which is formed by the combination of two or more elements, joined together in a fixed proportion.

Salt is a chemical compound which is formed by the reaction of an acid with a base. For example- NaCl ( sodium chloride) is a common salt. It is formed by the combination of two elements. Therefore, salt is a compound.

On the contrary, Phosphorous (P), sulfur (S) and Oxygen (O₂) are composed of a single element. Therefore, they are not compounds.

Thus, the correct answer for the compound is Salt .
