3. You have three molecules of glucose (3C6H12O6). How many oxygen atoms do you have?
C. 6

Question 1:

The right answer is A

Chemistry is a science of experimental nature that studies the composition of matter and its transformations.

Chemistry is thus interested in the elements that constitute matter (atoms, ions, etc.), in their properties and in the chemical bonds that can be created between them.

Question 2:

The right answer is A

Sodium chloride is an ionic chemical compound of the formula NaCl. It is more commonly called table salt or cooking salt, or simply salt in everyday language.

It is clear that it exists in the form of solid salts.

during his training, there was a physical change of sodium (metal) and chlorine (gas) into a salt.

Question 3:

This question is a little bit tricky

If we assume that the question is aimed at finding the total number of oxygen in all three molecules together, the answer is 18.

A glucose molecule is made up of 6 atoms of oxygens if we have three glucose molecules (assuming that they are bound), we multiply by 3 and this gives us 18 oxygen atoms.

Plants with specialized tissues that can transport fluids

Answers

The answer is vascular plants.

Vascular plants have specialized tissues that can transport fluids - vascular tissue. This tissue consists of xylem and phloem. Xylem transports water and minerals from the root to the upper parts of the plant. Phloem transports food and nutrients from the leaves, where they are produced, to the growing or storage parts of the plants.
