Answer:
Answer is explained below;
Explanation:
Mercury is a liquid metal that is released into the environment by both natural processes such as volcanic activity, weathering of rocks, etc and human activities such as waste materials from factories. The mercury that reaches the ocean and other water sources is converted into methylmercury by bacteria. Methylmercury is a neurotoxin that interferes with the nervous system and is easily absorbed by the human body.
The methylmercury is taken up by planktons. Small fishes consume large quantities of plankton. Tilapia is a small, short-lived freshwater fish. The methylmercury level in tilapia is lower than that of other fish. When large, long-living predatory fishes such as tuna, shark, king mackerel, swordfish, etc consume many smaller fish with low mercury levels, this causes accumulation of methylmercury at extremely high levels in their tissues over time i.e., the amount of mercury in such bigger fish biomagnifies.
So large, long-lived predators like swordfish and shark often have the highest methyl mercury levels than a small, short-lived tilapia.
Answer:
The correct order is
E. Adsorption
B. Penetration
D. Synthesis
A. Assembly
C. Lysis
Explanation:
Virus can have two reproduction cycle that is lytic and lysogenic. In the lytic cycle first step is virus adsorption or attachment on the host cell surface. The second step is penetration in which the virus penetrated the host cell and injects its genetic material in the host cell.
The third step is synthesis, in this stage, the viral genome gets incorporated and produces viral proteins required for capsid formation. The fourth step is assembly in which viral protein assembled around viral nucleic and form new viruses.
The final step is lysis where the new viruses lyse the host cell to come out of the host cell and infect other cells.
