One idea to mitigate the effects of burning fossil fuels on atmospheric co2 concentrations is to pipe liquid co2 into the ocean at depths of 2,500 feet or greater. at the high pressures at such depths, co2 is heavier than water. what potential effects might result from implementing such a scheme?
a) increased photosynthetic carbon fixation because of the increased dissolved carbon dioxide in the deep water
b) increased carbonate concentrations in the deep waters
c) reduced growth of corals from a change in the carbonate-bicarbonate equilibrium
d) no effect because carbon dioxide is not soluble in water
e) both increased acidity of the deep waters and changes in the growth of bottom-dwelling organisms with calcium carbonate shells

Option E, Both increased acidity of deep waters and changes in the growth of bottom-dwelling organisms with calcium-carbonate shells

Explanation:

When high concentration of CO2 is pumped into the ocean at its greater depths, CO2 is absorbed extensively by the ocean which changes the pH of ocean water and makes it more acidic. The high acidity of ocean water is due to the release of free hydrogen ions. Excess of hydrogen ions make the carbonate ions less abundant due to which the organism that make carbonate shell will suffer as they may not get sufficient carbonate ions to calcify their outer coverings.  

Hence, option E is correct

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
