If water had a low heat capacity, what could happen? all but one apply. a) temperature changes would require a great deal of energy input. b) temperature changes, especially in coastal ares would be sudden. c) the water in organisms would heat quickly and cause the cells to lyse. d) water in lakes and rivers would be much warmer in the summer and much colder in the winter.

A

Explanation:

Water acts a temperature buffer and regulates the fluctuations of temperatures in a cell of an organism and even outside within the habitat of organisms such as fishes.  The property that allows water to have this benefit is its high heat capacity. This means it required a lot of energy to have its temperatures raised by a degree (compared to most other substances) while also requiring to lose the same amount of energy to lower its temperature by a degree.

Therefore, even in very hot days water can ensure that an organism stays cool and that its protein structures do not easily denature from  a high environmental temperature rise, or freeze from low environmental temperatures. If water did not have this property, it would not be able to protect cells and organisms from high-temperature fluctuations.

answer: the blood-brain barrier is a layer of specialized membranes and cell processes designed to keep undesirable substances from passing from the bloodstream into the precious tissues of the brain. while the blood-brain barrier does keep most bad things out of the central nervous system, it is not impermeable.
