Unit 1
The broad branch of science that focuses on knowledge discovery.
What is Pure Science?
The comparison of one quantity to another.
What is a ratio?
A process by which water diffuses across a selectively permeable membrane.
What is osmosis?
A set of events that repeats during the life of a cell.
What is a cell cycle?
Segments of DNA that code for proteins.
What is an exon?
The study of life.
Complex proteins that lower the activation energy needed for a chemical reaction to occur.
What is an Enzyme?
An active transport process by which a vesicle moves a large substance out of the cell.
What is exocytosis?
Thin protein filaments that form between the two poles of a cell during mitosis.
What is Spindle fibers?
A handheld device that accurately measures out very small volumes of liquid.
What is a micropipettor?
A physical substance that takes up space and has mass.
What is matter?
A membrane made of two layers of phospholipids.
What is a Lipid Bilayer?
A type of active transport that involves carrier proteins which pump potassium into the cell and pump sodium out.
What is a sodium-potassium pump?
A diploid cell formed by the fusion of two haploid gametes.
What is a zygote?
A chemical reaction carried out in a thermocycler machine that makes copies of a DNA sequence which is flanked by two short primer sequences.
What is a polymerase chain reaction (PCR)?
