the relationship between form an f unction in the body; the study of how the parts of a system effect each other
connective, epithelium, muscular, nervous, osseous; tissue is made up of fibers, cels and fluids to allow for smooth processes to occur
the amount of negative charge that a molecule has; if it is very electronegative it will have many electrons around it

joint between your teeth and mandible
when you spread your fingers, or your arms/legs away from your body; opposite of adduction
concentric rings that are part of compact bone
why will you never be able to find a cell which is as big as a loaf of bread?
they can maximize their ratio of surface area to volume. as a cell grows, its surface area increase less than its volume does. cells must be able to change form depending on their function in an organism. They need a decent surface area in oder to better interact with other cells and molecules. they do this via cilia and microvilli. cells also want to be small in volume in order to more strictly regulate what can pass through it, such as chemicals, proteins and food. another reason cells need to be small is to prevent the unnecessary used of energy. they would waste energy on maintaining their size if they were as big as a loaf of bread.
describe 3 properties of water that make it essential for life as we know it
universal solvent - breaks down many molecules and this is important for biological processes
high heat capacity - water takes a long time to heat up, but once its heated it maintains that temp. for a long time, and it takes a while for it to cool. this is good for homeostasis.
cohesion - water is a polar covalent molecule that is able to hydrogen bond with molecules. it allows for cohesion in areas such as the lungs, which prevents the alveoli from collapsing upon exhalation.
