Steps of transcription and translation
What is DNA is copied onto a mRNA molecule (uracil replaces thyamine). The mRNA leaves the nucleus and enters the cytoplasm where it enters the ribosome. tRNA brings amino acids to create polypeptide strands. (proteins)

Tell me about enzymes.
What is enzymes are proteins that act as biological catalysts that lower the activation energy of a reaction? Can be affected by pH, temperature and concentration of the enzyme and substrate.

Differences between prokaryotes and eukaryotes.
What is membrane bound nucleus and membrane bound organelles?

Tell me about photosynthesis.
What is process used by plants, algae and certain types of bacteria that can transform carbon dioxide and water into sugars and oxygen, which are then used in respiration and are broken down into carbon dioxide and water.

Lipids
What is organic compound made of carbon, hydrogen and oxygen that is stored in tightly bound chains and is used for long term energy (example, oil, cholesterol (all -ols) Cell membranes are made up of lipids.

Stages of mitosis and how radiation can affect the cell cycle.
What is prophase, metaphase, anaphase, and telophase. radiation can prevent the cell from undergoing apoptosis and can allow mutated (cancerous) cells to continue growing.

If the producers in the food web are killed with pesticides, what will happen to the carnivores?
What is they will also die?

Properties of water
What is polar molecules create adhesion and cohesion (allow for surface tension- :"walking on water" and capillary action - water moving up through the xylem found in roots), it is lense dense as a solid than as a liquid and takes a lot of energy to heat up?

Tell me about the immune system.
What is the skin is the first line of defense? Then then white blood cells attack foreign matter, usually pathogens. An autoimmune disorder results when the immune system attacks non-pathogens. Epidemics occur when a pathogen , such as a virus (a virus does not have DNA and uses it's host's DNA to replicate) rapidly occur. Pandemics are when an infectious disease spreads around a continent or the world (Pan- pangea).
