1. a. Which of the following statements about the Thermoneutral Zone (TNZ) is TRUE? The TNZ is when the animals body temperature is the lowest. Animals need to eat the least amount of food in their TNZ. Both endotherms and ectotherms have a TNZ. This is the environmental temperature where the animal can move the fastest. Animals need to increase their metabolism to maintain their TNZ. b) Marine osmoregulators perform which of the following processes to survive in a salt-water...

QUESTION 14 Consider the following statements. Which is true about an ideal gas? CP Gas partides are not attracted to each other Gas particles behave independently of each other. Gas particles collide with each other and with the walls of the container without losing any energy. The volume occupied by the gas particles is very small compared to the total volume of the container which holds the gas. All of the above we true for gases.
