Answer: Option A) The seals would decrease in number and the phytoplankton would increase in number
Explanation:
The food web can be illustrated as follows: Seal --> Krill --> Phytoplankton
Where phytoplankton is the producer of food, krill is the primary consumer while seal is the secondary consumer.
So, reducing the krill population would immediately cause food shortage for seals, and lessen consumption of phytoplanktons.
Thus, the seals would decrease in number due to starvation and death, while the phytoplankton would increase in number
Answer:
Antinuclear antibodies are autoantibodies that bind to contents of the cell nucleus. In normal individuals, the immune system produces antibodies to foreign proteins but not to human proteins. In some cases, antibodies to human antigens are produced.
1. Nuclear waste:
The waste generated by nuclear reactors remains radioactive for tens to hundreds of thousands of years . Currently, there are no long-term storage solutions for radioactive waste, and most is stored in temporary, above-ground facilities. These facilities are running out of storage space, so the nuclear industry is turning to other types of storage that are more costly and potentially less safe .
2. Nuclear proliferation:
There is great concern that the development of nuclear energy programs increases the likelihood of proliferation of nuclear weapons. As nuclear fuel and technologies become globally available, the risk of these falling into the wrong hands is increasingly present. To avoid weapons proliferation, it is important that countries with high levels of corruption and instability be discouraged from creating nuclear programs, and the US should be a leader in nonproliferation by not pushing for more nuclear power at home .
3. National security
Nuclear power plants are a potential target for terrorist operations. An attack could cause major explosions, putting population centers at risk, as well as ejecting dangerous radioactive material into the atmosphere and surrounding region. Nuclear research facilities, uranium enrichment plants, and uranium mines are also potentially at risk for attacks that could cause widespread contamination with radioactive material .

The advantage of using pluripotent cells over multipotent cell is that pluripotent cells possess the capacity to give rise or differentiate into all various types of cell that constitute the body. An example of such cell is embryonic stems. The cells can also be replicated outside the body such as in a laboratory which is more likely to be rejected by the immune system.
Cadmium was discovered in 1817 by a physician, Friedrich Stromeyer (1776-1835). The element was first found in the condensation of vapors (mixed with soot and zinc oxides) that rose out of a furnace in which zinc oxide was being roasted. Cadmium's discovery is also loosely attributed to K.S.L. Hermann and J.C.H
