Cell structure
The movement of a substance from an area of high concentration to a low concentration.
What is diffusion?
The location of photosynthesis in a cell.
What is the chloroplast?
The step of mitosis when chromosomes line up at the middle of the cell.
What is metaphase?
When both phenotypes are clearly expressed in the offspring
What is codominance?

What is the ribosome?
The name for animals that eat other animals.
What is a heterotroph?
The point where two sister chromatids are attached.
What is a centromere?
Traits that are produced by the interaction of many genes.
What is polygenic inheritance?

Using energy to move things against a concentration gradient
What is active transport?
It is a step of cellular respiration that does not require oxygen.
What is glycolysis?
Proteins which control when to switch from one phase of the cell cycle to another.
What are cyclins?
Genes for different traits can segregate independently during the formation of gametes.
It is a point mutation that creates a new amino acid sequence.
What is a missense mutation?
