they represent only some 20 percent of earth’s classified and named organisms. In contrast, while the animals make up only a small fraction of the biomass, they represent more than 60 percent of the classified and named organisms—our supreme example of biodiversity. The animals’ ...
Protozoa aresingle-celled eukaryotes(organisms whose cells have nuclei) that commonly show characteristics usually associated with animals, most notably mobility and heterotrophy. They are often grouped in the kingdom Protista together with the plant-like algae and fungus-like water molds and slime mold...
Algae are an important part of the ecosystems where they occur, but they can also become a nuisance for aquarists, pond keepers and swimming pool owners. In order to successfully combat algae it is important to understand what algae are and how they subsist. Just like a land living plant, ...

Taxonomy is sub branch of biology that deals with classification of living things. There are different classes where living things are classified. Classification is based on the characteristics of both plants and animals. Classification is essential since it is easier to locate organisms....
How are flowering plants classified? What do Charophytes have in common with plants? What are the different branches of botany? What are the characteristics of vascular plants? What are some adaptations of animal-pollinated plants? How are algae and mosses similar?
Botanist Carl Linnaeus realized two and half centuries ago that humans needed a system for keeping track of our planet's species. He began classifying both plants and animals using taxonomic language that named, ranked and classified creatures and plants. ...
Science instructors need questions for use in exams, homework assignments, class discussions, reviews, and other instructional activities. Textbooks never have enough questions, so instructors must find them from other sources or generate their own quest
Enzymes are naturally occurring biologic agents present in many detergents in varying concentrations. These enzymes are typically classified into the following categories and are similar to the enzymes used by your body to digest food: Proteases: help break down proteins ...
