Unit 1
The first step in the Scientific Process
What is observation?
The smallest living thing
What is a cell?
A process in which molecules or ions move from areas of higher concentration to areas of lower concentration
What is diffusion?
A set of events that repeats during the life of a cell
What is the cell cycle?
An organism's genetic makeup, as determine by its alleles
What is a genotype?
The second step in the Scientific process
What is form a hypothesis?
Different organs that work together to carry out major body functions
What are organ systems?
A process by which water diffuses across a selectively permeable membrane
What is osmosis?
The stage of the cell cycle in which duplicated chromosomes become separated into two identical group
What is mitosis?
An organism's physical appearance, as determined by the traits that are expressed
What is a phenotype?
The third step in the Scientific Process.
What is conduct and expiriment?
Specialized structures of tissues that have specific functions
What are organs?
A process in which no energy is supplied by the cell to move substances across the cell membrane
What is passive transport?
During this phase, the paired chromatids attach to the spindle fibers and line up in the middle of the cell. The centrioles form the point of attachment.
What is Metaphase?
An enzyme that produces a copy of an existing DNA strand
What is DNA Polymerase?
