Answer #1

1. Charophytes (Chara)

This algae is most closely associated with land plants because like land plants have leaf, root and stem, this algae is also having leaf, root and stem in the body, although less differentiated.

2. Diseases like Malaria will be affected by global warming because the vectors which transmit these diseases will be affected by global warming. This is because global warming will increase temperature of the earth and this will make habitat unfavourable for the growth and Reproduction of these vectors. But on the other hand, areas which were earlier unfavourable may become now favourable for the growth of these mosquitoes. Therefore these diseases will be affected and may change the place where they are commonly found.

Either these diseases will be found in new places and will be lost from the older places or the prevalence of these diseases will either increase or decrease.

Please rate high.

    7. In certain species of plants, mutations can cause the electron transport chain connecting PSII to PSI to flip orientation. This change in orientation causes the electron transport chain to become ordered in terms of decreasing electronegativity instead of increasing electronegativity. What portions of photosynthesis will be affected by this change in the orientation of the electron transport chain? Why? 8. A mutation in the genome of a plant prevents proper folding of rubisco. How would this impact the Calvin...
