D. Toby is smart, but afraid to admit it
It is TRUE that coral reefs form when a<span> structure of calcite skeletons built up by coral animals in warm, shallow ocean water. </span>To form their skeletons, coral animals absorb the element calcium from the ocean water. The calcium is then combined with carbon and oxygen to form calcite (calcite is a mineral). When coral animals die, their skeletons remain. More corals build on top of them, gradually forming a coral reef.
Peptidoglycan is the answer
Answer: Phylum Basidiomycota .
The typical characteristic of Basidiomycota is the presence of hyphae and filaments.This phylum belongs to the kingdom Fungi.
Mushroom contains the basidium which is a club shaped spore containing organ.This facilitates the process of sexual reproduction.
Answer:
A. The synthesis of triose phosphates from 3-phosphoglycerate
Explanation:
ATP and NADPH are produced during light-dependent reactions of photosynthesis in chloroplasts. These molecules serve as an energy source and reducing power respectively during the Calvin cycle. Calvin cycle includes fixation of carbon into 3-PGA followed by reduction of 3-PGA into glyceraldehyde 3-phosphate (a triose phosphate).
The reduction step also uses NADPH as an electron donor. Two molecules of glyceraldehyde 3-phosphate make one molecule of glucose. A reduced ATP production during light-dependent reactions in chloroplast would not allow the reduction of 3-PGA into glyceraldehyde 3-phosphate. Without the formation of triose phosphate, glucose synthesis will also reduce.
