4 0

Answer:

Test tube 1 would <u>serve as a negative control</u> for the experiment.

Explanation:

<u>Heating of Benedict’s solution in the presence of monosaccharides would change the color</u>. However, when it has <u>no monosaccharides present</u>, the <u>color will stay the same</u>. So, in any experiment where you want to test the presence of monosaccharides (reducing sugars), you are supposed to heat the Benedict’s solution alone too so that you know that there was no contamination in the solution itself and then you can compare the results of test samples.

Destruction of tropical rain forests: helps maintain global temperatures
aliya0001 [1]

Answer:

B. reduces the amount of water vapor

Explanation:

Tropical rainforests is an area of vegetation comprising of predominantly trees. Trees play a major part in sustaining the environment, and hence, the destruction of trees will result in certain negative effects or impacts on the environment.

One of the effects of destroying rainforests according to the options in the question, is the reduction in the amount of water vapor. Trees in rainforests contribute to the addition of water vapor to the atmosphere via transpiration (loss of water through their stomata). Hence, destruction of tropical rain forests will reduce the amount of water vapor.
