Question

Cyclic electron flow may be photoprotective following experiments could provide A) use bacteria that have only cyclic flow and different light intensities B) Use mutated organisms that can grow but that cannot out cyclic flow of compare their abilities to photosynthetic in different light wild-type organisms. C) use plants with only photosystem I operative measured different wavelengths. D) use plants that can carry out both linear and cyclic electron flow or only one or another of these processes, and compare their light absorbance at different wavelength and different light intensities E) use bacteria with only cyclic flow and measured the number and types of photosynthetic pigments they have in their membranes When a potassium ion (K^+) moves from the soil into the vacuole of a cell on surface of a root, it must pass through several cellular structures. Which of the following correctly describes the order in which these structures will be encountered by the ion? A) primary cell wall - plasma membrane cytoplasm - vacuole B) secondary cell wall - plasma membrane primary cell wall - cytoplasm - vacuole C) primary cell wall - plasma membrane -lysosome - cytoplasm - vacuole D) primary cell wall - plasma membrane-cytoplasm - secondary cell wall - vacuole E) plasma membrane - primary cell wall - cytoplasm - vacuole

Explanation / Answer

Following are the answer from Question 18 - 20

18. Option (B) - The toy microscope magnifies a good deal, but has low resolution and therefore poor quality images.
In colleges labs, the microscope which is generally having higher resolution to get or obtain a clear images of the object and this higher resolution images will help to carrry out for research and training purpose. But to encourage small kids towards science, small reslolution lenses were used as a toy which is inexpensive and easliy affordable by parents of small kids.

19. Option (B) - Use mutated organism that can grow but that cannot carry out cyclic flow of electron and compare their abilities to photosynthesize in different light intensities against those of wild type organism

20. Option (A) - primary cell wall plasma membrane cytoplasm vacuole
