Allen's Rule: The warmer the climate the longer the appendages (ears, legs, wings) of warm blooded animals in comparison with closely related taxa from colder climes.
DNA, or deoxyribonucleic acid, is the central information storage system of most animals and plants, and even some viruses.
Haploid A single set of chromosomes (half the full set of genetic material), present in the egg and sperm cells of animals and in the egg and pollen cells of plants. Human beings have 23 chromosomes in their reproductive cells. Compare diploid.
Many eukaryotes, including stressed plants, insects, deep-sea animals and kidney tubule cells, adapt to environmental variation by making or accumulating diverse inositol derivatives as compatible' solutes.
Transmission from chimps to humans probably occurred while animals were butchered for food in sub-Saharan Africa, with animal blood contaminating wounds of humans.
Zoology is the discipline which involves the study of animals, which includes the physiology of animals is studied under various fields including anatomy and embryology.
Commonly found in wild animals such as the beaver, this graceful, flagellated organism may infect unwary hikers. But giardiasis can also be contracted via contaminated foods.
The glucose made by plants is used by plants and animals as a source of energy. To release the energy contained in the bonds of glucose, the glucose must be converted to ATP.
Ethology studies animal behavior (particularly that of social animals such as primates and canids), and is sometimes considered a branch of zoology.

Recombination occurs naturally in plants and animals during the production of sex cells (sperm, eggs, pollen) and their subsequent joining in fertilization. In microbes, genetic material is recombined naturally during conjugation.
