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 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.

to test for liberation of O2 in the light

Explanation:

Photosystem II is protein complex located  in the thylakoid membrane of plants with the major role in light-dependent reactions of photosynthesis. Photons of sunlight are absorbed by photosystem II and electrons within the system consequently become excited (pass through the cofactors). Electrons are replaced by water and hydrogen ions and molecular oxygen are formed.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
