Answer: Option D

Explanation:

The blood from the mother carrying oxygen, and essential nutrients is carried to the fetus.There is no different system available in the developing fetus which aids in its growth and development.

The region representing A provides oxygen and nutrients to the fetus and removes carbon dioxide from fetus.

This can be defined as an intersection between the fetus and mother so that there can be exchange of materials.

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.

s2008m [1.1K]

The options attached to the above question are given below:

A) The boys at first were very polite about my medals and asked me what I had done to get them.

B) I showed them the papers which were written in very beautiful language of full of fratellanza and abnegazione but which really said with the adjectives removed that I had been given the medals because I was an American.

C) after that their manner change a little toward me although I was their friend against Outsiders

D) I was afraid but I was never really one of them after they had read the citation because it had been different with them and they had done very different things to get their medals.

E) I had been wounded it was true but we all knew being wounded after all was really an accident.

ANSWER

The correct option is D.

In the statement given in option D, it can be seen that the speaker was formerly a soldier, who had fought in a war and had been awarded a medal to that effect. But despite knowing about this meritorious service that he had rendered to his country and the award he was given, he was not really accepted as an inner person by the group of people that was refereed to in the statement. They did not think much of him.
