total magnification= ocular magnification + what is the formula for total magnification?
objective magnification
ocular and objective what are the two types of lens on a microscope?
resolving power ability to reveal detail to distinguish 2 closely spaced objects as being 2 things rather than 1
1. refractive index what factors can change the resolving power?
2. wavelength of light
3. angle aperture

, monosacharide what is the basic structural unit of a carbohydrate?
monsacharide single sugar
reducing sugars sugars with free aldehyde or keytone group
condensation 2 monosaccharides form disaccharides and H2O is released, thus making it the product
hydrolysis H2O is used to split a disaccharide. H2O is the reactant
tryglycerides what is the most common type of fat?
amino acid
carboxal group

yellow to red-orange
starch what does the Lugol's reagent test for? what will be the color if the test is positive?
blue-black
lipids what does the Sudan IV reagent test for? what will be the color if the test is positive?
large red drops will form
amino acids what does the Ninhydrin reagent test for? what will be the color if the test is positive?
purple or yellow
