Answer:
''they can no longer support their own weight'
Explanation:
The statement ''they can no longer support their own weight'' is a prediction and the scientist has to verify this prediction by performing different experiments on the plant. The scientist has to take a plant and placed in dark in order to see the fall over of plant. If the plant fall over so the we can say that the prediction was right while if the plant did not fall over so it means the prediction was wrong.
Answer:
Explanation:
Bacteriorhodopsin is one of the simplest protein from a family of a protein called opsin which is present in photosynthetic bacteria, algae and few fungi.
The bacterio-rhodopsin acts as an active light-gated proton pump which can pump the protons against their concentration gradient and then establishes concentration gradient across the membrane.
When the photosynthetic bacteria gets exposed to the light, bacteriorhodopsin pumps the proton from the cytosolic side to outside. This establishes electric motive force across the membrane which causes disequilibrium of protons.
The protons move back from the outside of the membrane to inside through H+ATPase which help allow the generation of ATP in the cell.
His experiment with his swan. Expedia flask disproved spontaneous generation in that broth was left open to air yet no life grew in the broth, the neck design of the flash trapped all possible contaminates. This broth today is still sterile despite sitting in a museum for decades.
