Answer:
The correct answer is 6.67 %.
Explanation:
The average osmotic pressure of the brain is 300 mM
Given the concentration of solution is 280 mM
Difference is 300 - 280 = 20 mM
This difference is sufficient to stimulate osmosis and make water move from CSF to the brain until the concentration becomes similar.
Also, it is known that the volume of brain is about 1200 ml on an average,
Volume of fluid moved because of osmosis = 20 mM / 300 mM * 1200 ml = 80 ml
Percent swelling of brain = 80 ml / 1200 ml * 100 = 6.67 %

Answer:
In India, in West Bengal, the shrimp found in a particular river were not deemed healthy to be eaten.
Explanation:
All water bodies have their own <em>food chains and ecosystems</em>. So basically in aquatic ecosystems, lot of marine animals are considered edible. The examples are fish, shrimp, prawn, lobster, crabs , etc are cooked and eaten.
Larger fish have a tendency to eat smaller fish. Anything that the smaller fish eats goes into the stomach of the larger fish and gets <em>accumulated</em>. Due to large industries not dumping their waste properly, lot of it falls into the water bodies. The waste contains toxic minerals like lead and mercury which when eaten by humans can cause poisoning.
Lead poisoning can cause loose motions, vomiting, cramps and infection in the abdomen etc.
