It is found throughout the body—covering it; lining organs, vessels, and cavities; and forming glands. It absorbs nutrients, transports electrolytes, secretes hormones, and regulates body temperature by producing sweat. We begin with some general principles…

What do you know about prokaryote structure and the gram stain? Bacteria are members of a unique taxonomic kingdom consisting of prokaryotic unicellular organisms. Prokaryote is a term from ancient Greek meaning “before the kernel.” The kernel in this case is a nucleus, which prokaryotes lack. Prokaryotes also do not have any membrane-bound organelles. In…
