A DNA molecule takes this shape.
What is a double helix?
100
In passive transport, molecules move in this direction along a concentration gradient.
What is down?
100
A typical cell spends 90% of its time in this phase.
What is interphase?
100
Genetic material is stored in this in prokaryotes.
What is the cytoplasm?
100
A good experimental design features these two groups.
What are the control group and the variable group?
200
Strands of DNA are wrapped around this kind of protein.
What are histones?
200
Movement of molecules down a concentration gradient is known as this process.
What is diffusion or passive transport?
200
The S phase of the cell cycle is when this happens.
What is DNA replication/synthesis?
200
Plant cells are surrounded by these two structures.
What is the cell membrane and cell wall?
200
Enzymes lower this to facilitate reactions.
What is activation energy?
300
Prior to replication, DNA condenses into this X-shaped structure.
What is a chromosome?
300
Movement of water down a concentration gradient is known as this process.
What is osmosis?
300
Mitosis occurs when this divides, while cytokinesis is when this divides. (TWO REQUIRED ANSWERS)
What is the nucleus and the cell membrane?
300
Rough endoplasmic reticulum is different from smooth endoplasmic reticulum because it has many of this protein-making organelle.
What are ribosomes?
300
Cancer is often a result of this.
What is uncontrolled cell division?
400
Humans have this kind of arrangement of chromosomes; there is a set of two of each chromosome.
What is diploid?
400
Movement that requires energy is called this.
What is active transport?
400
During mitosis, human cells go from a total of 46 chromosomes to a total of this many.
What is 46?
400
These are the two organelles that have their own DNA besides the nucleus.
What is the mitochondrion and the chloroplast.
400
Fermentation produces this substance in human muscle cells.
What is lactic acid?
500
In a DNA molecule, cytosine pairs by this kind of bond to this other nucleotide. (TWO REQUIRED ANSWERS)
What is a hydrogen bond to a guanine base?
500
Molecules moving down a concentration gradient but with the help of a protein is a process known as this.
What is facilitated diffusion?
500
"Crossing over" in meiosis is a process that increases this.
What is genetic variability?
500
Animal and plant cells both have vacuoles, but they are different because of this.
What is a single central vacuole (plant) and a few small vacuoles (animal)?
500
