Why is myelin important in the nervous system? A. It allows signals to travel faster along axons because depolarization occurs only at myelinated locations. B. It allows signals to travel faster along axons because depolarization occurs only at nonmyelinated locations. C. It bundles the dendrites of adjacent neurons together. D. It increases capacitance across the cell membrane, which helps electrical signals to leave the axons. E. It traps neurotransmitters, increasing their concentratio...

insterstitial fluid : fluid located between cells and among tissues cuboidal epithelium : cube shaped epithelial cells that function in secretion, and are located in various endocrine glands simple columnar epithelium : lines intestines, secretes digestive juices and absorbs nutrients, one cell thick pseudostratified ciliated columnar epithelium : forms a mucous membrane in portions of the respiratory tract; contains cilia that move the film of mucous stratified squamous epithelium ...

Eukaryote : An organism whose cells contain complex structures enclosed within membranes. The defining membrane bound structure thats sets them apart from prokaryotic cells is the nucleas or nuclear envelope within which the genetic material is carried. All species of large complex species are eukaryotes, including animals, plants and funghi. Euchromatin : This shows as pale areas in the nucleas under electro magnification. It is a less densly packed form of chromatin; 10% is even l...

Mycorrhizae : Symbiotic organisms (aka symbionts) with plants that live on their roots, helping the plant gain nutrients Nerve net : A nervous system that moves neural signals in all directions from the stimuli, found in invertebrates like hydra Malpighian tubules : Tubes in an insect that help with osmoregulation and excretion; they move waste into the main gut for removal. "Kidneys" of arthropods, they absorb ammonium and convert it into uric acid, then into the main gut for rem...

Both amino acids and nucleotides form complex chains. Select all the answers below that are accurate. A. The chains formed by both have polar phosphate groups. B. Both contain peptide bonds. C. Both contain nitrogen. D. The chains formed by both can be lysed by trypsin. E. The sequence of chains both form from preexisting templates. : C. Both contain nitrogen. E. The sequence of chains both form from preexisting templates. When a population is in Hardy-Weinberg equilibrium, which of th...

What enzyme does HIV use to convert RNA to DNA? : Reverse Transcriptase The promoter region of a prokaryotic gene is located ______ to the gene and is the binding site for ______. : 5'...RNA polymerase Which of the following is TRUE of prokaryotes? I. Simultaneous transcription and translation II. Presence of intron sequences III. Circular DNA : I and III only Integral transmembrane proteins are proteins imbedded in the cell membrane. Which of the following amino acids would you...

biological form is known as this : anatomy biological function is known as this : physiology this term means tapered on both ends; streamlined body contour : fusiform rate of exchange (for things like nutrients, waste products, and gases) is proportional to this : (membrane) surface area amount of material exchanged is proportional to this : volume as body size increases, the ratio of surface area to volume ___creases : de 2 | P a g e as body size decreases, the ratio of surface a...
