Biochemistry
This type of weak bond forms between the partial negative oxygen of one water molecule and the partial positive hydrogen of another water molecule.
Hydrogen Bond
These are structures in eukaryotic cells that allow compartmentalization (e.g., nucleus, mitochondria). What are they called?
Organelles
Polar molecules tend to require a protein to transport through a cell membrane. Small molecules like oxygen pass through the cell membrane easily because they are ___________.
Nonpolar

Term for when water molecules stick to other substances (e.g., water to glass).
Adhesion
Which structure is primarily responsible for digesting phagocytized bacteria in animal cells?

Facilitated diffusion
Which stage of photosynthesis uses ATP and NADPH to convert CO2 into sugars?
Calvin Cycle
What is the stage called when the cytoplasm divides and two daughter cells separate?
Cytokinesis
This is the only fruit that bears it's seeds on the outside.
The strawberry
Which property of water, caused by polarity, makes water an excellent solvent for ions?
Polarity enables it to bond with both positive and negative ions
Which cell structure in some freshwater unicellular eukaryotes expels excess water to maintain proper ion concentration?
Contractile vacuole

Carbohydrates
What is the role of the ribosomes on the rough endoplasmic reticulum?
synthesis proteins for export
Which membrane proteins help molecules pass through the membrane when they cannot cross by simple diffusion?
The glucose molecules produced through the process of photosynthesis can be combined to form other molecules that are needed by a plant such as cellulose or starch. What term would best describe this process? (Type of metabolism)
Anabolism
In meiosis I, what process increases genetic variation by exchanging DNA between homologous chromosomes?
Crossing overt (recombination of non sister chromatids)
How many eyes do bees have?

If a single amino acid change alters a protein’s primary structure and leads to a different final shape, what will happen to the function of the protein?
It will change
Which mitochondrial feature (described as a double membrane) is directly involved in creating a proton gradient used to make ATP, and where is that gradient established?
The inner membrane has specialized proteins that create a hydrogen ion concentration gradient between the intermembrane space and the matrix
When you add salt water to an Elodea cell and the membrane pulls away from the cell wall, what is this process called?
Plasmolysis
The leaves
If a root-tip cell shows condensed sister chromatids aligned at the metaphase plate with kinetochores attached to spindle microtubules, what will happen next in mitosis?
Paired chromatids will separate, and the new daughter chromosomes will move toward opposite poles (anaphase)
What is the human body's largest organ?
