Answer:
Object A but not object B
Answer:
meiosis I, anaphase
Explanation:
During meiosis 1, anaphase, the homologous chromosomes separate towards the opposite poles,line up in a random order and in crossing over, create genetic diversity.
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
Because the process will start and end with the same molecule.
