Answer: Option (A) is the correct answer.

Explanation:

A mixture is defined as the substance that contains two or more different number of substances which are physically mixed together.

For example, a mixture of mud and water can be separated through the process of filtration.

A pure substance is defined as the substance which contains either same or different type of atoms that are chemically combined to each other in a fixed ratio by mass.

For example, both Cl_{2} and MgSO_{4} are pure substances.

A pure substance can only be separated by chemical means.

Thus, we can conclude that one difference between mixtures and pure substances is that mixtures can be physically separated.

Describe how diffusion and osmosis move substances through a plant. Must have two examples.​
Jlenok [28]

Osmosis help plants to absorb water from soil. Diffusion is the process by which carbon dioxide from the stomata diffuses to the leaves and then to the cells.

Explanation:

  • Example one - The genetic modifications in some of the plants can help in survive and adopt the osmosis in a very dry environment. They develop defense methods to handle the water loss.  
  • Example two - Some plants in a permanent dry environment like desert have special structures like reduced leaves, sunken stomata, and so on to conserve water and thus achieves diffusion.
  • Another example for diffusion - loss of water vapour from leaves to the atmosphere. Another example for osmosis - the roots of the plants have high concentration than the surrounding soil and hence water flows into the roots.
