C.
Every change in a species is coded within the DNA. But the bird had lost a toe an accident. So the toe-loosing-option isn't true because not every bird looses his toe.
(Example: If a women gets bitten by a snake on the arm and gets the arm removed from her body and then in a year or so has a baby with her new husband. The baby won't be born with one arm because his/her mother lost her arm.) <span />
Answer:
D -- ATP synthesis when the phosphate donor is a substrate with high phosphoryl transfer potential
Explanation:
Substrate- level phosphorylation is the synthesis of ATP from ADP by the transfer of phosphoryl group from a substrate with high phosphoryl group potential to the ADP molecule.
In substrate-level phosphorylation, the donor is a phosphorylated intermediate molecule with a high phosphate transfer potential and it is a way through which phosphate in introduced into a molecule, the other two ways are oxidative phosphorylation and photophosphorylation. In substrate-level phosphorylation, a PO4^2- is transferred from a phosphate intermediate (substrate) to ADP to form ATP. Phosphorylase and kinases are enzymes involved in this reaction. An example is the reaction in glycolysis which involves phosphoenolpyruvate and ADP to form Pyruvate and ATP. This is to ensure adequate supply of energy to cells and also during anoxia so as not to make mitochodria strain the glycolytic ATP reserves.
Answer:
c
Explanation:
Nitrogen has a number of important uses. It can be used to replace air and eliminate oxidation of materials. Its most important use is in creating ammonia, which in turn is used to make fertilizer and explosives. Liquid nitrogen is used as a refrigerant for very low temperatures
