Photosynthesis
What happens to the number of oxygen atoms during photosynthesis?
The number of oxygen atoms increases as plants make and release oxygen gas.
Explain what is true about multicellular organisms.
Similar cells group together to make organs.
Identify the primary function of the excretory system.
The excretory system removes wastes through the kidneys.
Describe the cause of Pellagra.
A deficiency in niacin (B3)
Explain what happens to the amount of matter during a chemical reaction.
The amount of matter is conserved because the number and type of atoms remains the same
Explain what is conserved as plants rearrange molecules to make sugar.
The number of oxygen atoms is conserved as plants rearrange molecules to make sugar.
Describe what tissues are made of.
Tissues are made of similar cells that help it perform a specific function
Explain how the excretory system helps maintain homeostasis.
By regulating the body's fluid balance and removing waste.
Name the person who conducted research to find a cure for Pellagra.
Dr. Joseph Goldberger.
Describe what the student’s model shows regarding food and energy.
The transfer of matter when humans eat food to gain energy.
Identify the gas plants take in during photosynthesis
Carbon dioxide
Explain what organs work together to create.
Organ systems with specific functions.
Name the organs primarily involved in the excretory system
Kidneys.
Identify the symptoms of Pellagra
Skin rashes, mouth sores, diarrhea, and mental deterioration.
State what happens to complex molecules in a reaction.
The amount of matter decreases because complex molecules are broken into simpler molecules
Name a byproduct of photosynthesis
Oxygen gas
State whether individual cells are specialized in multicellular organisms.
Tissues and organs have specialized functions, but individual cells do not.
State what substances the excretory system helps remove.
Waste products such as urea and excess salts
Explain the dietary changes that helped those suffering from Pellagra.
A diet including more meat, vegetables, and milk.
Explain why it is important that the amount of matter is conserved.
It ensures that all atoms are accounted for in a chemical reaction.
State the process by which plants convert sunlight into energy.
Photosynthesis
Describe the role of organs in multicellular organisms
Organs work together to perform specific functions.
Identify the process often confused with the function of the excretory system.
Gas exchange of oxygen and carbon dioxide.
State why cells need B vitamins.
Many cells need B vitamins to function properly
Describe how energy relates to the food we eat.
Energy is released when food is broken down during digestion.
