Science Practices
What is biology?
The study of life
Give an example of an autotroph.
Plants, some types of algae.
What subatomic particles make up the nucleus of an atom?
Protons & neutrons
What type of transport is used to transport gases like O2 and CO2?
Simple diffusion
In what organelle does cellular respiration occur in?
Mitochondria
You want to do an experiment to see if what you drink before a race affects how quickly you run. What is the independent variable?
Types of drinks
Identify the following type of symbiotic relationship: The spider crab and the algae. Spider crabs live in shallow areas of the ocean floor, and greenish-brown algae lives on the crabs' backs, making the crabs blend in with their environment, and unnoticeable to predators.
Mutualism
A __________ bond is formed as a result of sharing electrons.
covalent
What are the stages of interphase?
G1, S, G2
In light-dependent reactions, electrons are ultimately received by what molecule?
NADP+
True or False: All living things have either DNA or RNA.
True.
Organize the following from smallest to largest: biome, ecosystem, population, organism, community, biosphere
organism, population, community, ecosystem, biome, biosphere
Identify the type of bonds that form between individual water molecules.
Hydrogen bonds
What is the name of the structure that helps separate chromosomes during mitosis?
Spindle fibers?
How many total ATP are generated during cellular respiration?
36 ATP
Human beings rely on insulin to regulate blood glucose levels. What characteristic of life is this an example of?
Homeostasis
Describe the type of growth in the following example: Seals rely on krill as a food source. When the krill populations are abundant, the seal population increases. The krill population suddenly decreases, causing the seal population to decline until the resources stabilize.
Logistic growth
Identify the name of the electrons that are available for bonding.
Valence electrons
What is the end result of mitosis?
2 cells that are identical to the parent cell
Which steps of cellular respiration are solely aerobic?
Krebs Cycle and Electron Transport Chain
List the 6 characteristics of life.
Organization (cells), genetic material, the ability to grow, develop and reproduce, response to an environment, homeostasis, and metabolism
A rabbit relies on dandelions for food. In the trophic pyramid, 90,000 kcal of energy are available in the producer level. How much of this energy is obtained by the rabbit?
9,000 kcal
Monosaccharides, amino acids, and nucleotides
As the size of the cell increases, what increases at a faster rate, volume or surface area?
Volume. This means the surface area-to-volume ratio decreases, making it harder for the cell to transport materials in and out efficiently.
In cellular respiration, ATP synthase produces ATP that is released into _____________________.
The mitochondrial matrix
