Question

76. In skeletal muscle, endurance exercise a. increases VEGF levels, causing increased angiogenesis and leading to greater numbers of capillaries. b. increases the number of capillaries, allowing greater VEGF expression. c. decreases the number of capillaries, causing decreased VEGF expression. d. decreases VEGF levels, causing decreased angiogenesis and leading to fewer 77. In skeletal muscle cells, resistance training typically results in an increase in a. the number of mitochondria. b. the amount of Type llx myosin c. muscle fiber diameter d. muscle fiber length 78. The rate of convective gas transport depends on the a. partial pressure of a particular gas in solution. b. rate of fluid flow. c. total concentration of gas in the fluid. d. rate of fluid flow and the total concentration of gas in the fluid

Explanation / Answer

Q76. Answer is A. Increase VEGF levels,causing increased angiogenesis.

This VEGF is the major target in Anti Angiogenesis. Which is nowadays widely used in cancer treatments.

Q77. Answer is C. Increase musclefibre in diameter.

Due to resistance training in adaptations in muscles,tendons and ligaments it is mainly seen. It is also known as Hypertrophy.

Q78. Answer is D.

In a bronchal tree representation we can see that the gas is simply transported by Convection or, Bulk flow and a single respiratory unit where the gas is uniformly mixed. This convection dominates throughout the phase 1 region.
