Chang described two substances which participate in photosynthesis.

substance a: plants absorb sunlight.
substance b: gas formed with glucose.

which statement is correct?

- substance a is chlorophyll and substance b is oxygen.
- substance a is oxygen and substance b is carbon dioxide.
- substance a is glucose and substance b is carbon dioxide.
- substance a is carbon dioxide and substance b is oxygen.

- Substance A is chlorophyll and Substance B is oxygen.

Explanation:

Chlorophyll is the green coloring matter responsible for the green color of a leaf.

It helps in trapping sunlight for the purpose of photosynthesis.

In the event of photosynthesis, carbon dioxide is used, the gas produced is oxygen.

This makes the right choice be the first option.

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.

3. a complex molecule containing he genetic code is dna or deoxyribonucleic acid.

4. an enzyme refers to a molecule of protein, which is unique in accelerating up a particular chemical reaction in the biological systems.

5. nucleic acid refers to an sequence of sugars, phosphates, and nitrogenous bases, for example, dna and rna.

6. a protein refers to a large, composite organic molecule comprising of a huge number of amino acids associated together with the of peptide bonds.

7. rna refers to a nucleic acid that takes part in the production of proteins.

8. substrate refers to a compound, which takes part in a chemical reaction, and is chemically modified by the reaction.
