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.

<h3>What is Evolution?</h3>

This is described as the process in which heritable characteristics are changed in species over successive generations. This occurs as a result of natural selection in which the traits suitable for survival are passed to the offspring.

This is usually as a result of a change in the environmental factors which ensures that the organisms are able to adapt so as not to die out and go extinct in this type of scenario.

Valentin [98]

Answer:

B. Cellulose

Explanation:

Polysaccharide are substances that contains many units of monomers called MONOSACCHARIDE. They are carbohydrate molecules consisting of very long chains of monosaccharides like glucose, galactose etc.

An example of molecule that forms from strong chains of polysaccharides is CELLULOSE, which consists of long chains of glucose units linked together by B-1,4-glycosidic bonds. Cellulose is the most abundant polysaccharide on Earth found in plant cell walls.
