I'll have to admit: people can act pretty strangely in single's bars and other places where reproductive urges overrule good sense. But that's nothing compared to a buck deer. In the first place, he has the strange habit of growing bones on the top of...

Penguins live in the freezing climate of the Antarctic.At least that's what most people believe, whether they are getting their information from biology textbooks or the animated movie "Happy Feet." However, the image of penguins living ONLY in icy climates isn't actually 100%...

Two processes make most life work on the earth. The first one, photosynthesis, takes raw minerals and produces sugar for consumption. The second, respiration, takes in sugar and burns it for energy. Under ideal conditions, these two processes offset each other. Without photosynthesis, ultimately, what...

What are mosquitoes good for? That depends on what kind of critter is answering the question! Ask my goldfish and they would say that without the mosquito larvae I give them as treats, their lives would be dull and lifeless. Ask many freshwater fish living...

Why do animals camouflage themselves?Well there are a few answers to this and all of them have to do with evolution.An animal that has the capability of slightly or intensively it's colors don't usually only use it for camouflage but for other reasons...

Throughout thousands of years of evolution, animals have evolved a variety of different methods of protection that suit their local environments. Some of these animals have resorted to using foul smells, which are obnoxious to predators, ultimately driving them away. Some produce horrible tastes, which...

The process of duplication can be applied to segments of DNA ranging from individual structural or functional domains to entire genomes. Whatever the size of the duplicated region, a contribution can be made to evolution. Genes - and therefore proteins - can be extended, copied...

Retrotransposons are DNA sequences that have the ability to move around the genome. They rely on the reverse transcription of RNA to DNA to move about the genome. In mammals retrotransposons fall into three classes: LTR retrotransposons (retrovirus-like elements), LINEs, and SINEs.LTR TEs are...

DNA sequences in eukaryotes are classified according to the number of copies present in an average genome, which can range from one to more then ten thousand. The three main types are highly-repetitive, middle-repetitive, and single-copy sequences. Highly-repetitive DNA can be further classified as satellite...

Photosynthesis is the basis for life on Earth. Simply put, a plant (and some bacteria), take six molecules of carbon dioxide, six molecules of water, and with the input of light energy, turn these into one molecule of glucose and six molecules of oxygen. The...
