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
The DNA undergoes two simplified process I becoming a protein; transcription and translation. Transcription involves the production of a complimentary mRNA strand in the nucleus. The double stranded DNA unzips enzymatically, next DNA polymerase binds to the unzipped DNA and binds complementary nucleotides from the 3' end to the 5' end. This newly formed mRNA strand then moves out of the nucleus where it binds with a ribosome, here complimentary tRNA molecules bind to the mRNA strand thus forming a primary structure protein.
Germ cells are also diploid, but they are found only in the gonads. Gonads are the ovaries in females and testes in males. <span>Gametes are </span>haploid cells<span>, which means that they have only one set of chromosomes. </span>
The answer is; C
This phenomenon is called bottleneck effect and drastically affects small populations in comparison to large ones. The mudslide wipes off most of the population B at the base of the hill base. Due to their small population, a large proportion of the population is lost and the pollution loses most of its alleles leaving a small proportion to continue the population succession. Its diversity is hence reduced as it repopulates. The larger population is not greatly affected because it covers much of the hillside.
