Explanation:
The salt solution is meant to lower the ice melting point hence keep most of the water from turning into ice even at zero degrees temperatures. The salts are dissolved in the water to form a salty solution that percolates the ground and reach plant roots. Because the salty water is hypertonic (more concentrated) to the cell cytoplasm of the plant roots, water is drawn from the plant by osmosis. This is the reversal of normal plant root absorption of water from the soil. This causes the plant root to wither and subsequently the whole plant to die. Remember in osmosis, water moves from the less concentrated solution to the more concentrated solution through a semipermeable membrane.

Answer:
There are prion-like particles in the brain normally, and when these become abnormal they can cause disease. (Ans. A)
Explanation:
Prions are proteins which can trigger normal proteins to fold abnormally, and they are present in the brain. They are causing many types of neurodegenerative diseases in both humans and animals. Which are known as transmissible spongiform encephalopathies.
Prions can enter the brain with the help of infection, also can arise from the gene mutation that encodes the proteins, and sometimes this affects humans by infected meat.
If a person infected from prion disease, it affects central nervous system tissues like brain, eye tissues and spinal cord.
Answer:
Carbon-14 has a half-life of 5,730 years. Taking one atom of 14C, this will either have decayed after 5,730 years, or it will not. But if this experiment is repeated again and again, it will be seen that the atom decays within the half life 50% of the time.
