Explanation / Answer

53. Location F refers to the Abdominal cavity, so the answer is E. none of these

54. The area D refers to the Thoracic cavity, and it is lined with serous membrane called as Parietal pleura, so the answer is B.

55. The dura matter is a thick membrane made of connective tissue that sourrounds brain and spinal cord. Thus the answer is A. A the cranial cavity.

56. Most of the energy needed to drive energy-requiring chemical reactions in the body is provided by the hydrolysis of

D. Adenosine triphosphate (ATP)

57. In an average lean health adult, 55% to 60% of the body weight is composed of

C. Water

58. A molecule that dissociates into one or more hydrogen atoms when dissolved in water is an

B. Acid for example HCl dissociates in water as H+ and Cl- which is an acid.

59. The most acidic solution is

A. pH 4
