Summary Introduction
Introduction: Water is the main component in the bodies of animals. Many solutes ions like Na+ and K+ are dissolved in the water of an animal’s body. Water and ions maintain the homeostasis of the organism.

- Increasing the concentration of solutes increases osmotic potential, hence water potential decreases. A. Agree, because presence of solutes increses osmotic pressure and thus osmotic potential. C. Agree, because they just represent the same values. D. Disagree, because it is the decrease in water pressure that decreases osmotic potential. B. Disagree, because presence of solutes increases osmotic pressure which decreases osmotic potential.arrow_forwardWhat processes occur in biological tissues when direct current is passed through them?

- Which of the following is TRUE of sharks and other osmoconformers? A. The solute concentration inside the organism is maintained at a higher level by active import of solutes. B. The total solute concentration is the same inside and outside of the organism C. The solute concentration inside the organism is maintained at a lower level by active export of solutes. D. The NaCl concentration is the same inside and outside of the organismarrow_forwardThe functional unit of the mammalian kidney is similar to a piece of dialysis tubing. Quantities of blood plasma that contain dilute amounts of the waste product urea are filtered into the nephron. The concentration of urea in the developing urine is increased by moving water from inside the nephron to the outside. Urea is a larger molecule than water, and unlike water, cannot pass through the membrane of the nephron. Imagine you have been given a piece of dialysis tubing that simulates the nephron membrane, a dilute solution of urea in water, and a beaker of salt water. Applying the concepts and methods used in this investigation, describe how you could concentrate the dilute solution of urea. You can use a drawing to help explain your ideas.arrow_forwardThe movement of water and electrolytes between fluid compartments is regulated primarily by _______ A.

How do you determine whether this animal is an endotherm or an ectotherm? (A) You know from its high and stable body temperature that it must be an endotherm. (B) You subject this reptile to various temperatures in the lab and find that its body temperature and metabolic rate change with the ambient temperature. You conclude that it is an ectotherm. (C) You note that its environment has a high and stable temperature. Because its body temperature matches the environmental temperature, you conclude that it is an ectotherm. (D) You measure the metabolic rate of the reptile, and because it is higher than that of a related species that lives in temperate forests, you conclude that this reptile is an endotherm and its relative is an ectotherm.arrow_forward
