What is the biggest whale in the world? It is the blue whale. Adult can measure 30 meters in length! However, she only eats tiny animals. If not hunted can live more than 50 years. Why do whales expel large jets of water? Whales can dive for almost half an hour holding their breath, but they are forced to rise to breathe.
In order to obtain healthy plants and a productive garden, the soil must contain water. Water holding capacity depends on soil type. Water, as a solvent liquid, dissolves the salts in the soil, so that plants can absorb them. Not all rainwater flows directly into streams, streams and rivers.
In an ecosystem, there are many types of interactions between the components of the various species. We can classify relationships between living beings initially into two groups: intraspecific, which occur between beings of the same species, and interspecific, between beings of different species. It is common to differentiate relations into harmonic or positive and inharmonious or negative.

As we have seen, glycolysis consists in the transformation of one glucose molecule over several steps into two pyruvic acid molecules. In this process four hydrogens are released, which combine two by two, with molecules of a cell substance capable of receiving them: NAD (nicotinamide adenine dinucleotide).
There are various techniques for preserving foods so that they do not spoil, lose their nutritional value, or undergo any kind of alteration. The main ones are: boiling, cooling / freezing and dehydration. Boil Cooked foods stay longer than raw foods, because boiling kills the microorganisms contained in the food.
