Answer to Question 1

Answer: (B)

Answer to Question 2

Answer: It is supplied to the atmosphere by plant and animal respiration, the decay of organic material, volcanic eruptions, and natural and anthropogenic (human-produced) combustion. Carbon dioxide is removed from the atmosphere by photosynthesis, the process by which green plants convert light energy to chemical energy. For many decades, the rate of carbon dioxide input to the atmosphere has exceeded the rate of removal, leading to a global increase in concentration. The increase has occurred mainly because of an increase in anthropogenic combustion and, to a lesser extent, deforestation of large tracts of woodland.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
