Answer:
Option A
Explanation:
Another name for folic acid is folacin and this is required for cells to produce a metabolite caled formate which is involved in the synthesis of nucleotides. The enzyme involved in its absorption/conversion is dihydrofolate synthetase and not folacin.
Answer and explanation:
Monophyletic species are the species whose lineage belongs to the common recent phylogenetic ancestor. As mentioned in the question, the girl has 3 species namely G, H, and K. Because there is no other criteria given, we assume that the closeness of alphabets would reflect the closeness of species. Thus, G and H are closer relative than K. Therefore, if she adds <u>I, and J species</u> in the list, all of them will be closer relatives and we can say that they are monophyletic now.
Answer:
No
Explanation:
During cyclic photophosphorylation, electrons are cycled continuously out of and back into the reaction center of PSI. It does not involve PSII and plastoquinone. During non cyclic photophosphorylation, the reaction center of plant photosystem II passes electrons to plastoquinone. The reduced plastoquinone carries electrons to the cytochrome b6f complex. Since PSII and plastoquinones are not included in cyclic photophosphorylation, dichlorophenyldimethylurea would not affect the process.
Answer:
E. All the answer options are correct.
Explanation:
Cilia are very small hair-like, membrane-bound cell structures. They are present on the surface of many eukaryotic cells. They are made of microtubules and are continuous with the plasma membrane of a cell. On a single cell, they are present in large numbers as compared to flagella. The major function of cilia is to move the cell or to move substances such as mucous, fluid over or around the cell.
