If your cat or dog has diarrhea accompanied by fever, vomiting, blood in the stool, or lethargy, consult your veterinarian immediately, as these are serious symptoms. In these cases, hospitalization, antibiotics, and IV fluids might be necessary to treat your pet.
Biological diversity, or biodiversity, is the variety of life either in a particular place or on the entire Earth, including its ecosystems, species, populations, and genes. Conservation thus seeks to protect lifeâs variety at all levels of biological organization.
Adaptation is one of the two main processes that explain the diverse species we see in biology, such as the different species of Darwin's finches. The other is speciation (species-splitting or cladogenesis), caused by geographical isolation or some other mechanism.
