Answer: C- Beach erosion may increase on the downdrift side of the jetties.
Explanation:
Beach erosion may increase on the downdrift side of the jetties.
On the up drift side of a jetty there is accumulation of sand while the opposite effect takes place on the down drift side. This erosion is caused by the jetty due to the lack of sand which is trapped on the other side. Ironically, Jetties,which are built to prevent erosion, end up causing more damage than providing a solution.
Answer:
The correct answer is option D. Osmosis
Explanation:
Osmosis the process in which high solute concentration molecule move to low concentration molecule through the semi-permeable membrane.
In the hypotonic solution, a cell get lysed due to solute movement into the cell whereas in a hypertonic solution cell shrink due to movement of solute out of the cell.
Thus, the correct answer is option D. Osmosis.
Answer:
In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.
Explanation:
Answer:
Explanation:
Restriction enzymes refer to enzymes that is produced by a bacteria which has the ability to cleaves DNA property to a specific restriction sequence site within the molecule.
Restriction enzyme is use to cut DNA into smaller fragments by preventing the replication of the phage DNA .
Restriction enzyme is use when there is infection or foreign materials that intrude into a bacterium,the bacterium uses it to defend itself against infections that might be cause by viruses, pathogens e.t.c.
Bacteria genome can be edited using CRISPR method. It is done with recombineering, which is a technique that uses phage recombination method to enhance homologous recombination of DNA fragments.
