PNB 2250 Exam 3 Complete Questions And Answers With Latest Quiz Of the following, which is NOT a strategy by which endotherms generate internal heat: ANS Panting The minimal metabolic activity required to maintain bodily functions in a mammal is known as the ANS basal metabolic rate. Which of the following thermoregulatory mechanisms can be used to restrict blood flow to the skin, and thus decreases heat loss by keeping the warmed blood closer to the core of the body?

Name an animal that has neither a circulatory system nor a respiratory system and relies solely on cutaneous diffusion for gas exchange. How is this adequate for its survival? - Small and thin animals, like flatworms and horsehair worm parasites, have no respiratory or circulatory systems and solely rely on cutaneous/cuticle diffusion through water or air. Examples of respiratory structures of aquatic animals - bulk flow (sponges, cnidarians), gills, water vascular system, arborescent respi...

Examples of respiratory structures of terrestrial animals -:- bulk flow with tracheal system and spiracles (insects), cutaneous (frog) Examples of respiratory structures of aquatic animals -:- bulk flow (sponges, cnidarians), gills, water vascular system, arborescent respiratory trees (sea cucumber), cutaneous (leech) Do all aquatic animals necessarily exchange gasses in water? -:- No, some aquatic animals could exchange gasses above water using lungs, like aquatic mammals, or cuta...

_______________ have a single or multiple solute binding pockets and after solute binding, a reversible conformation movement exposes the solute-binding pocket to the other face of the membrane. - transporters Because of the factors affecting diffusion, H2O will move from an area of higher concentration (low osmolarity) to an area of lower concentration (higher osmolarity) if the cell membrane is permeable to H2O [6.03]. The movement of H2O in this way is a very powerful force, capable of r...
