Part E Water can exist in three different states of matter: solid, liquid, and gas. The water molecules are the same in each sta

te, but the distance between them changes as water changes state. Space your four molecules evenly on one sheet of paper. Now place the second sheet of paper next to the first sheet, so the long edges of the sheets are touching. Space your four molecules evenly over both sheets of paper. Compare the two models. Does this demonstration show how the distance between water molecules can change? Were the molecules more tightly-packed on one or two sheets of paper? Explain.

Answer:

No.

Explanation:

No, the demonstration did not show the distance between water molecules change because the four molecules are evenly spaced on both the paper sheet. If we want to demonstration the distance between water molecules of different states we have to make the diagram of water molecules of solid having less space as compared to liquid while liquid has less space as compared to gas state of water. Yes, the molecules were more tightly-packed on both sheets of paper which shows that more force of attraction is present between them.

Answer:

B. 20%

Explanation:

The complementary base-pairing rule states that Adenine always pairs with Thymine (A with T), and Cytosine with Guanine (C with G).

Because of this, the amount of Adenine present must be the same as the amount of Thymine present, and the same for Cytosine and Guanine.

This means that if there is 30% Adenine, there is also 30% Thymine as each A base is paired to a T base. This adds to 60%, so Cytosine amounts and Guanine amounts must add to 40% to make 100%.

Since they are equal in amount, there must be 20% of each.

Therefore the answer is B. 20%

There is 30% Adenine, 30% Thymine, 20% Guanine and 20% Cytosine.

Hope this helped!

Describe how the granite of a mountain could change first into sandstone and then into quartzite.
Naily [24]
Weathering causes the granite to break down into small particles - sand. The sand becomes buried and compacts into sandstone. If the sandstone continues to be buried and comes into close contact with high heat, such as magma, it can be turned into quartzite.
