Some photosynthetic organisms contain chloroplasts that lack photosystem ii, yet are able to survive. the best way to detect the lack of photosystem ii in these organisms would be to test for liberation of o2 in the light. to determine if they have thylakoids in the chloroplasts. to test for co2 fixation in the dark. to the action spectrum for photosynthesis.

acceleration= v2-v1/t so 8m/s-3m/s / 3s =to 8/3 or

2.67 m/s^2

true is the

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.
