- a Cell division involving one cell with the diploid number of chromosomes dividing into two identical cells.
(used for repair of tissues and growth of the organism)
- b Spinal vertebre
- c movement of molecules from an area of greater concentration to an area of lesser concentration along the concentration gradient. Very slow process. FOR MOLECULES
(Example: exchange of gases in lungs or body tissues)
- d bodys response to stimuli reverses the stimulus in effect turning it off for a while and keeps the body within normal range

(ex: strand of hair maintains its shape)
- Serous membranes: line some closed body cavities and cover the organs in those cavities (thoracic and abdominal cavities) CAVITIES THAT AREN'T OPEN TO AIR
Mucous Membranes: line the body tracts that have openings to the environment and have a mucous membrane to keep the lining of the cells wet (vagina, trachea, esophagus and stomach)
- diffusion of water through a selectively permeable membrane. water will move from an area with more present to an area with less water present. takes place in the kidneys which reabsorb large amounts of water. FOR WATER
- Covalent bonds share electrons between atoms
(ex: H20 or water)
5 True/False Questions
What are the 2 major types of membranes found in the body? → - cell membrane
- cytoplasm and organelles
What is contained in the pelvic cavity? → Contains skull and brain (CNS)
Describe a Hydrogen bond? → does not involve the sharing of electrons but results in hydrogen atoms
(ex: water molecules are attracted to nearby water molecules to form surface tension)
What are the different kinds of bonding atoms? → 1. Sagittal plane which divides left from right (cut down the middle would be mid-sagittal)
2. Frontal plane which divides the body front to back (Coronal)
3. Transverse plane which is a horizontal plane that separates the body into upper and lower portions (cuts you at belly button into upper body and lower body)
What is contained in the abdominal cavity? → liver, stomach and intestines
