Dinosaurs is a very broad term which includes both the ancestors of birds as well as modern reptiles. But that analogy stretches as far to say that a bird is a modern dinosaur and a reptile is a modern dinosaur but a bird is not a reptile. Both of their ancestors lived during the cretaceous period and tend to get lumped together. Another analogy would be ...

Short answer Birds emit infrared. Background Objects with a temperature higher than the background emit detectable infrared (IR). Endothermic (warmblooded) animals keep their body temperatures at around 37oC and given the relatively cool temperatures at the earth's surface, endotherms generally emit more IR than the background. Endothermic animals include ...

This is difficult to answer exactly since the thermodynamics of cellular metabolism are not well understood. These are spontaneous reactions, so there is certainly a loss of Gibbs' energy $\Delta G < 0$; this energy corresponds to your "energy" term on the product side of the reactions. For the anaerobic case (glycolysis) a balanced reaction formula is ...

In biology, anaerobic respiration is a way for an organism to produce usable energy, in the form of adenosine triphosphate, or ATP, without the involvement of oxygen; it is respiration without oxygen. This process is mainly used by prokayotic organisms (bacteria) that live in environments devoid of oxygen. Although oxygen is not used, the process is still ...

The excellent answers from Chris and One Face have already written about why the claim is wrong, so I'm going to add a hypothesis for how this sort of nonsense could even originate in the first place. The reason why lemons are acidic is because they contain a lot of citric acid, so in a solution part of this citric acid ionizes to citrate which increases ...
