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.

Explanation:
The correct order for the bone cells from unspecialized stem cell to highly specialized mature cells is Osteoprogenitor Cells, Osteoblasts and Osteocytes so the correct answer is A.
I believe the answer to this is the temperature range.
Answer:
After one round of replication, there will be only two layers one of 14 N and second of 15 N labelled. This is because of total conservation of template. If it was semi-conservative then an intermediate layer will be formed composed of one strand of 14 N and other strand of 15 N. This intermediate strand did not appear in this conservative replication state.
