Document Summary
World of bees compromises 20- 40,000 species. Bees can be thought of as specialized vegetarian wasps. Eat pollen for protein (from flower) and nectar which fuels them for flying. Genus/species: the 2 names organisms are referred to as species are reproductively isolated from each other (most can"t interbreed) Dna: genetic material of both prokaryotes and eukaryotes, main component of chromosomes. Virus particles do not have dna but instead contain rna as genetic material. Nucleoid: central region of cell where dna of bacteria is located and forms a compact double stranded loop. Nuclear chromosomes: complexes of dna and chromosomal proteins found in eukaryotes. Genome: total dna complement. Chordata: phylum that we as human beings, along with other mammals, birds, reptiles, amphibians and fish belong to. Arthropada: phylum that compromise most of the animal species. Arthropods have jointed legs. Exoskeleton: skeleton on outside of body (armor suit) Advantages to exoskeleton = protective, minimizes water loss.
