Your lab partner will be Thomas. You estimated his wingspan and said "150cm". Then Thomas estimated your wingspan and said "120cm." After that, you guys went to go measure each other's wingspan. Thomas's actual wingspan is 150cm and yours is 145cm. Then both of you found the difference. Thomas's difference is 0, and yours is 25
Later, both of you estimated each other's height. You estimated Thomas's height and said "150cm". He did the same and said "130cm" You guys then found each other's actual height. His is 149 and yours is 146. After that, you guys found the difference. Thomas's difference is 1, and yours is 16.

Based on the results of your measurements, do you think there is a relationship between human wingspan and height? If so, what do you think it is? State you answer in the from of a hypothesis. ( Okay, fine. This is my homework. I really really really really really really really really need help. Please answer!) I'l choose best answer!

A heart attack may occur as a result of the blocking of the coronary arteries. Its is remedied by a coronary bypass operation. This involves grafting sections of the vein from the patient's leg to the heart.
