Answer:
B) Changes in the temperature and salinity of water.
Explanation:
<em>Options</em>:
A) Migration of bottom feeders into the region.
<u>B) Changes in the temperature and salinity of water. </u>
C) Migration of fresh water fish to places near the mouths of rivers.
D) Formation of breeding grounds for various species in the shallow waters.
Sea level changes are among the most relevant issues that our planet is facing due to climate change. This phenomenon impacts the salinity and temperature of the ocean because of the melting of glaciers, and ice sheets. Therefore, <u>melting ice alters the level of salinity of the water which, along with temperature, also effect the density of the ocean water, altering ocean currents and productivity.</u> These impacts alter the distribution, behavior, and ecology of marine organisms.
<em>*Note: The melting of the glaciers and ice sheets - result of anthropogenic climate change - has increased sea level.</em>
The population will increase causing an overpopulation of rats.

Answer:
Each strand has a 3' end (unbound hydroxyl group) and a 5' end (hydroxyl group of deoxyribose sugar), the two strands run antiparallel to each other. (Ans. E)
Explanation:
DNA is known as Deoxyribonucleic acid. It is a complex organic molecular structure and present in all eukaryotes, prokaryotes and some viruses. For the transmission of inherited traits DNA codes genetic information.
It is a double-helix polymer consist of two spiral DNA strands fold around each other. Each strand of DNA is made up of a long chain of nucleotides. DNA's nucleotide consist phosphate group attached with deoxyribose sugar and nitrogenous bases two purine (adenine, guanine) and two pyrimidine (cytosine, thymine)
DNA have two distinct ends, one is 5'prime another is 3'prime. It means 5' and 3' carbon present on the sugar. 5' prime end consist phosphate group and 3' prime end consist hydroxyl group.
