ability of cells to communicate with adjacent cells within an organism
Answer:
A. Oxygen
Explanation:
A is the only one that makes sense because plants take in carbon dioxide, use glucose for food, and use energy to photosynthesize, and the only answer they don't use is A (oxygen) because they only produce it but not use it
A. When the substance is in its gaseous state.
<u>Explanation:</u>
When a substance is expanding against its constant volume and pressure, its temperature increases except when the substance is in gaseous state and not in liquid or solid state. So the internal energy increase in the system not only increases and maintaining the volume and pressure of the system remains constant in its gaseous phase. In the first law of Thermodynamics, it is used specifically that to especially in the case of gaseous system.

Answer:
The two enzymes that are used during DNA replication is helicase and polymerase. Each enzyme has distinct role that made it a vital part of the replication. In the course of DNA replication, the initial stage is to unzip the double helix structure of the DNA molecule by the enzyme helicase, which breaks the hydrogen bonds that holds the complementary bases of DNA.
Moreover, the DNA polymerase has the ability to exactly copy a DNA template. This enzyme binds to the leading strand and then adding a new complementary nucleotide bases to the DNA strand. In addition, it catalyzes the joining of deoxyribonucleoside 5′-triphosphates (dNTPs) to form the increasing DNA chain.
Explanation:
Matter can be neither created or destroyed so if we 3mol of Cl2 then we have 6 total
So the answer is 6
