Having a triangular obturator foramen E. Being weaker than the female pelvis Most herniated disks result from: A. Slippage of the fibrocartilage disk B. The transformation of fibrocartilage to hyaline cartilage within the disk C. The degeneration and protrusion of the nucleus pulposus D. The loss of annulus fibrosus elasticity E. Continuous pressure on the spinal cord The importance of water to living systems reflects A. Its polarity and solvent properties B. Its high heat capacity C. Its chemical reactivity D. Its high heal of vaporization E. All of these. Which of the following pairs is mismatched? A. Endoderm-bone B. Mesoderm-muscle C. Ectoderm-skin D. Neuroectoderm-nervous system E. Neural crest cells-peripheral nervous system, skin pigments, tissues of the face The four most abundant elements in the human body are A. Carbon, hydrogen, oxygen, and iron B. Carbon, hydrogen, oxygen and potassium C. Calcium, hydrogen, sodium and potassium D. Carbon, oxygen, magnesium, and zinc E. carbon, sulfur, calcium, and potassium Depolarization of the cell membrane occurs when thre is a rapid influx (inflow) of A. Calcium ions B. Potassium ions C. Chloride ions. D. Sodium ions E. Amino acidsExplanation / Answer
52. Answer is C
This is due to the greater concavity of the pelvic bone which is smaller in females and so in the female, the coccyx is not so anteriorly placed.
53.Answer is E
All the other options are the evidences found in herniated disk.
54.Answer is A
Though all other properties also holds good, for a living system to survive the transport of nutrients across potential differences is the most important requirement and this is fulfilled by water.
55. Answer is A
Endoderm-will form the digestive tract,pancreas, liver, etc. All others are true matches.
56.Answer is B
Elements present in human body in descending order of magnitude-Oxygen(approx65%),Carbon(approx19%), Hydrogen(approx10%), Nitrogen(approx4%), Carbon(approx2%) and Phosphorous(approx1%).
57. Answer is D
Depolarization involves the loss of polarization leading to charge difference between the interior and exterior of the plasma membrane of a muscle or nerve cell due to influx of sodium ions into the cell.
