Answer:
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
Obligate parthenogenesis is the process in which organisms exclusively reproduce through asexual means. Many species have been shown to transition to obligate parthenogenesis over evolutionary time.
Answer:
D
Explanation:
Carbon is a basis for all life on earth
Answer:
Pollinators are critical for blackberries and raspberries, and countless other fruits of summer.
Explanation:
Explanation:
Monosaccharides are defined as the simplest form of carbohydrates. It consists of carbon atom, hydrogen atom and oxygen atom.
In disaccharides and polysaccharides, monosaccharides are the basic building blocks.
As two units of a monosaccharide leads to the formation of a disaccharide. Similarly, more than two units of a monosaccharide will lead to the formation of a polysaccharide.
Basic formula of a monosaccharide is 
, where n can be equal to or greater than 3.
