Photo/CR
How would lack of sunlight affect photosynthesis?
Lack of sunlight would cause a decrease in the rate of photosynthesis
What cell part is responsible for building proteins?
Ribosomes
What is the difference between an autotroph and a heterotroph?
An autotroph (plant) makes its own food from the sun whereas heterotrophs(humans) must eat something for energy
What macromolecule is not found in foods?
Nucleic Acids, DNA/RNA
I am a low number on the pH scale (0-6)
What is an acid?
What are the products of Photosynthesis?
What are the products of CR?
Photo: Oxygen, Glucose
CR: CO2, ATP, Water
What body part do you think would contain more mitochondria - the leg or the stomach?
leg - areas with more muscle (like legs) have more mitochondria because muscle contains more mitochondria to process energy
Why is an energy pyramid more narrow at the top?
Energy is lost as heat through chemical reactions like metabolism, breathing, hunting, etc.
- 10% rule
What are the 4 macromolecules?
Give an example of each one.
Carbohydrates - bread, pasta, rice, veggies
Lipids - oil, butter
Proteins - meat, beans, leafy greens
Nucleic acids (not found in foods) - DNA & RNA
Which of the following best explains why biodiversity is important to the stability of ecosystems?
a. Biodiversity increases the likelihood of competition, which strengthens populations.
b. Ecosystems with high biodiversity are better able to withstand environmental changes and disturbances
c. High biodiversity ensures that all organisms have equal access to resources.
d. Biodiversity reduces the chances of predation by balancing food web dynamics.
C
What are the reactants for Photosynthesis?
