which one of the plants pictured below was given water mixed with salt, and which one was given pure water? Explain how you know
ludmilkaskok [199]

The plant on the right must have been the one given a saltwater mixture while the one on the left must have been given pure water.

<h3>Osmosis</h3>

Looking at the attached image closely, one would see that the plant on the right has withered leaves while the leaves of the plant on the left seem to be flourishing.

The plant on the right must have been the one fed with water mixed with salt and here is the reason. Adding water mixed with salt to the soil on which the plant grows will decrease the water potential of the soil relative to the water potential of the plant's root. Thus, water will move from the plant into the soil through the root by osmosis. This will cause the various cells of the plant to become flaccid, and hence, the withered leaves.

On the contrary, the plant on the left must have been fed with pure water. Feeding the soil with pure water will increase the water potential of the soil relative to the water potential of the plant's root. Thus, water will move from the soil into the plant through the root by osmosis. This will cause the various cells of the plant to become turgid, and hence, the flourishing leaves.

Which term refers to a change in one species that results from a change in another species that it interacts with?
Mrac [35]
The answer is coevolution.

Coevolution is a change in <span>one species that results from a change in another species that it interacts with. For example, some species of orchid and African moth coevolved. That was a consequence of African moths' dependence on flower nectar and the orchids' dependence on moths' help in pollination. This two species coevolved, therefore the orchids have deep flowers while African moths have long proboscides.</span>
