Unit 1
a broad branch of science that focuses on knowledge discovery
pure science
Basic building blocks for all living organisms
cells
The different methods that cells use to transport materials across the cell membrane without using any additional energy of their own are known collectively
passive transport
a form of reproduction in which the cells produced are genetically identical to the original/parent cell
asexual reproduction
an organism's genetic makeup, as determined by its alleles
genotype
The study of life
biology
supports the body tube of a microscope
arm
passageways from one side of the cell membrane to the other
channel proteins
a form of reproduction in which two parent cells unite to form an offspring that contains DNA which is a mixture of DNA from both parent cells
sexual reproduction
Two scientists that developed images of DNA through the process of X-ray diffraction.
Franklin and Wilkins
The variables that are kept the same in an experiment
controlled variables
the amount of space in a three-dimensional boundary
volme
a process by which energy is used to transport a substance against its concentration gradient
active transport
An organized picture of an organism’s chromosomes, and it shows what the chromosomes look like and how many are present in a typical cell.
Karyotype
A change to the sequence of bases in DNA
The cause of a mutation
