What is CARBON and the Carbon Cycle?
What is a Carbon is a essential element found and is the "backbone" to all organic molecules. Carbon Cycle is a process of how the Carbon molecule moves within each reservoir of the world. Carbon is cycle through the ground, air, plants oceans, human/animals, and rivers and play a role with each other

What is Carbon,Hydrogen, Nitrogen, Oxgyen, Phorphorus and Sulfur.
Carbon: building block of life and is found in all organic molecules, EX:carbohydrates, lipids, proteins, nucleic acids
Hydrogen: a component of water (H2O) and is also present in various organic molecules
Oxygen: a component of water (H2O) and is also present in various organic molecules
Nitrogen:a crucial element in amino acids, building blocks of proteins, and is also a component of nucleic acids (DNA and RNA).
Phosphorus:a key component of nucleic acids and is also present in ATP (adenosine triphosphate), which stores and transfers energy within cells.
Sulfur: Sulfur is found in certain amino acids, contributing to the structure of proteins.
Weak attractions between polar molecules are called...
What is hydrogen bond

Yes! all ascpectof the Carbon Cycle occurs relatively the same way
What is the difference between a pure substance and a compound ?
What is pure substance consist of a single type of atom (Periodic Table of Elements) whereas a compound consist of chemical substance of two or more different elements (Na Cl and H2O)

Due to the polarity of water, compounds that dissolve in water contain
a. nonpolar bonds. b. ionic bonds.
c. polar bonds. d. both b and c.
What is D-both ionic bonds and polar bonds

This past weekend, Brooklyn has witness a massive wildfire in Prospect Park that destroyed over 2 acres of land and many living organisms dead. The gas that was release from the wildfire spread out the entire borough. The gas in this case is _________________ which can be harmful to human beings as a (increase/decrease) ______________ of this gas can cause respiratory issues.
Carbon Dioxide, increase
