Heat from the Earth's core and radiation from the Sun is transferred to the surface of the Earth by conduction. Contact of the atmosphere with these warm surfaces transfers thermal energy, which then heats up the rest of the air through convection.
The atmosphere is also slightly heated by absorption of electromagnetic radiation from the Sun. The warm land and water radiates infrared, some of which is absorbed by the atmosphere, adding to its thermal energy. The remaining heat on the surface is sent out into space in the form of infrared radiation.
The evolution of molecular biology has made possible to establish a new classification of all organisms according to their DNA, and it's called phylogenetic classification.This classification groups living beings according to their kinship, established according to anatomical, physiological and behavioral criteria and especially genetic, based on the similarity of genes between species.
This made it possible to discover kinship ties between species of which there is no suspicion of any morphological link between them, something which the old classification (the traditional classification) was incapable of doing (and this proves the importance of the DNA and genes in organisms classification.
Explanation: Compound: A substance that is made up of more than one type of atom bonded together. Mixture: A combination of two or more elements or compounds which have not reacted to bond together; each part in the mixture retains its own properties.
If i am not mistaken , the answer is
- enzymes are not changed by facilitating a reaction
-enzymes lower the activation energy of a reaction
-enzymes are specialized proteins.
i am sorry if my answers were wrong .
All DNA is remarkably similar, but some more than others. Humans' DNA would be closer to other mammals' than it is to, say, a bird. Using DNA shows how varied an animal really is from another. Specific parts of the DNA code for different things, so you might see a similar structure for wings and flippers.
