Homeostasis
What is homeostasis?
Why is cellular respiration important?
Every living thing needs energy to survive, and cellular respiration is how cells get that energy.
What is the importance of photosynthesis
It is how plants make their own food.
Which system is made up of bones?
Skeletal System
Describe what a reactant is in a chemical equation.
The reactant is the beginning structures or "ingredients" before a chemical reaction.
Negative Feedback
What are the reactants for photosynthesis?
Water, Carbon Dioxide, and sunlight
What are the products of Photosynthesis?
Glucose and Oxygen
Which organ system's job is to facilitate gas exchange between oxygen and carbon dioxide?
Respiratory
Describe what a product is in a chemical equation.
The end product of a chemical reaction
What is a response to an event increases the likelihood of the event to continue?
Positive Feedback
What is the 1st step of Cellular Respiration?
Glycolysis
What are the products of cellular respiration?
Carbon Dioxide, Water, and ATP
Which Organ system's job is to sense stimuli and communicate it with the brain?
Nervous System
Does it matter which side on the arrow the reactants and the products are on? Why?
Yes it matters because the arrow should always be point towards the products.
Give an example of positive feedback.
Breastfeeding mothers producing more milk
Which cells go through glycolysis? How do you know?
Eukaryotic and prokaryotic cells since they both have cytoplasm and that is where glycolysis occurs.
What are the reactants for cellular respiration?
Oxygen and Glucose
What is the largest organ in the human body?
The Skin
Why do chemical equations have to be balanced? Why not just leave them unbalanced?
We have to follow the law of conservation of mass. Matter cannot be created nor destroyed.
Fill in the blanks correctly: The process that helps your body maintain a stable internal environment is called ______. When your body sweats to cool down, it is an example of ____ _________. Blood clotting is an example of ______ _______. The main goal of homeostasis is to keep your body _______. Shivering when you are coldis a way your body tries to ______ its temperature.
The process that helps your body maintain a stable internal environment is called Homeostasis. When your body sweats to cool down, it is an example of Negative Feedback. Blood clotting is an example of Positive Feeback. The main goal of homeostasis is to keep your body Balanced. Shivering when you are coldis a way your body tries to Raise its temperature.
Explain why eukaryotic cells better at using glucose.
Eukaryotic cells have mitochondria which means they can go through the additional steps of Cellular respiration, which produces more ATP.
Which organelle is largely responsible for photosynthesis to occur in plants?
Chloroplast
Which organ system is made up of these organs?
Bone Marrow, Thymus, Lymph Nodes, and Spleen
Balance the following chemical equation:
_CH4 + _O2 --> _CO2 + _H20
1CH4 + 2O2 --> 1CO2 + 2H20
or (Since the 1 isn't necessary)
CH4 + 2O2 --> CO2 + 2H20
