Although we think of land when we hear the word biome, there are also aquatic biomes. the abiotic factors that influence life forms vary with location within ocean systems. oceanographers divide the ocean into five broad vertical zones as seen in the chart above. compare the characteristics of the five zones. where would you expect to find the kelp forest, a type of algae, pictured here and why? a) algae live in the top two zones in the ocean because light penetrates both zones. b) algae can live in the three top zones. the abyss is too dark for the algae to survive. c) algae live only in the epipelagic zone because it is the only zone with enough light for photosynthesis. d) algae live throughout the five oceans zones because they are the producers that are the base of all food webs.

Which term best describes the form sound takes as it travels away from a drum (a- gas)(b-music) ( c-waves) (d-particles

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
