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 of the following is true of all greenhouse gases?
My name is Ann [436]
<span>Which of the following is true of all greenhouse gases?
</span>
C. THEY TRAP ENERGY IN THE ATMOSPHERE.

They are not naturally occurring. They are the result of human activity like using electricity, burning fuel, etc. 

They don't exist in fixed quantities and they don't reflect incoming radiation. The volume of greenhouse gases emitted depends on the activity done. It also does not stay in one place, it moves around and combines with other green house gases; trapping heat in the atmosphere and making the Earth warmer.
