5 True/False questions
What is an enzyme and what does it do? → Catalyst: speed up reactions without the use of external energy or heat
What is active transport and how does it work? → Requires energy of mechanical pressure. Water and dissolved materials are FORCED through a membrane from an area of higher PRESSURE to an area of lower PRESSURE
(Example: formation of tissue fluid and the first step in the formation of urine)
Describe a covalent bond? → Covalent bonds share electrons between atoms
(ex: H20 or water)
Name some ways the body uses homeostasis? → ability of the body to maintain a relatively stable metabolism and to function normally despite changes
What is contained in the spinal cavity? → Spinal vertebre
