2. to determine if the type of agar affects bacterial growth, a scientist cultures e. coli on four different types of agar. five petri dishes are set up to collect results: • one with nutrient agar and e. coli • one with mannitol-salt agar and e. coli • one with macconkey agar and e. coli • one with lb agar and e. coli • one with nutrient agar but no e. coli all of the petri dishes received the same volume of agar, and were the same shape and size. during the experiment, the temperature at which the petri dishes were stored, and at the air quality remained the same. after one week the amount of bacterial growth was measured.

primary succession begins with a bare rock and ends with a forest secondary succession begins after a natural disaster where there is a temporary setback after a forest fire or local destruction, but the surrounding area can fill in

answer: after carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.

explanation:

on the planet jupiter, the acceleration due to gravity is approximately 26 m s2 , roughly 2.7 times the acceleration due

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
