For a science project, Brad takes his temperature several times a day over the course of a week. He only takes his temperature when he is relaxed and has not been exercising. When he charts his temperature vs the time of day, he gets the following graph: The graph shows that Brad's body temperature A. is affected by many different variables. B. is a cycle that is 24 hours long. C. controls his patterns of sleeping and being awake. D. changes by 4°C over the course of a day.

B. is a cycle that is 24 hours long.

Explanation:

The graph shows that Brad's body temperature is a cycle that is 24 hours long. Although he took the data over the course of many days, all his data fit into one shape, or pattern, with its position mainly determined by the time of day.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
