USPshnik [31]

Answer:

A solar eclipse can occur only when new moon occurs close to one of the points (known as nodes) where the Moon's orbit crosses the ecliptic. ...

The masses of all the substances either used up or formed during photosynthesis are shown below: A = 192 grams, B = 108 grams, C
qwelly [4]

Answer:

B.) The total mass of B and C, which are water and carbon dioxide, is equal to the total mass of A and D, which are oxygen and glucose.

Explanation:

The following statements that support the conclusion that photosynthesis follows the law of conservation would be B.) The total mass of B and C, which are water and carbon dioxide, is equal to the total mass of A and D, which are oxygen and glucose. We can conclude this because the law of conservation states that for any transfer of mass, it will always stay the same, meaning that you cannot add to it nor remove from it. Option A would not be correct because the question asked about photosynthesis, and A is describing cellular respiration. Options C and D would also not be correct because when you add up the values in the way that they are listed, it does not sum up to the statement. Here are all of the letter combinations added together, based on the letter choices:

B and C ➡ 372

A and D ➡ 372

A and B ➡ 300

C and D ➡ 444

A and C ➡ 456

B and D ➡ 288

Notice how the first two listed add up to 372. And because this matches option B, that will be your answer.
