How would lack of sunlight affect photosynthesis?
Lack of sunlight would cause a decerase 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
What is the correct order of the phases of mitosis?
Prophase, Metaphase, Anaphase, Telophase
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 Photo?
What are the reactants for CR?
Photo: Sunlight, water, CO2
CR: Glucose, Oxygen
Photosynthesis occurs in the __________ of plant cells while cellular respiration occurs in the ___________ of both animal and plant cells

What are the 4 symbiotic relationships and what are their symbols?
I will give you one, you give me the other 3.
Predation, +/-
Commensalism, +/o
Parasitism, +/-
What are enzymes? What do they do for the body?
Enzymes are proteins (helpers of the body) that do all the chemical processes we need to keep living (digestion, metabolism, movement, etc.)
What type of growth occurs when there at limiting factors that cause a population to reach carrying capacity?
Logistic growth (logical)
mitochondria
ATP
