The systems
What are the skeletal systems functions?
The functions support, protection, movement, store minerals and make blood cells.
What is anatomy?
Study of the body structures.
What is the purpose of Meiosis?
To make sperm and egg cells.
What are traits controlled by?
Two genes called alleles
What is DNA?
DNA is the molecule that contains instructions for life.
What gives color to the skin?
Melanin
What is physiology?
The study of how body parts work.
What is the purpose of mitosis?

What are the directional terms?
Superior=above, Inferior=below, Anterior=front, Posterior= back, Proximal=closer to body and Distal= farther from body.
What is the difference between Haploid and Diploid?
A diploid is a full set of chromosomes, body cells and made by mitosis. A Haploid is a half set of chromosomes, sperm and egg cells and made by meiosis.
What are the phenotype of an organism?
The traits and expressed genes and they are observable.
What is the difference between DNA and RNA?
DNA is a double strand, has thymine, stays in nucleus and stores information.
RNA is a single strand, has uracil, can leave nucleus and helps make proteins.
