Answer:
The burning of fossil fuels produces gases like sulfur dioxide and carbon dioxide which trap the sun's heat radiations and increase the overall temperature of the Earth. So the answers are A & B.
Explanation:
Global warming is caused by burning fossil fuels. The <em>carbon dioxide </em>produced as a result captures the heat in the surrounding atmosphere and causes a <u>rise in temperature</u>. Recently, it has been observed that the glaciers are melting and each year the net temperature of the core of the Earth is <em>increasing</em>.
The other gas produced is sulphur dioxide which is responsible for the acid rain. The sulphur dioxide combines with water to form sulphuric acid which causes damage to buildings and people. E.g Taj Mahal, in India is getting corroded by acid rain.

Answer:
The process by which a cell responds to substances outside the cell through signaling molecules found on the surface of and inside the cell. ... Signal transduction is important for cells to grow and work normally. Cells that have abnormal signaling molecules may become cancer cells. Also called cell signaling.
Egg activation, whether initiated by or independent of fertilization, induces a rise in intracellular calcium. This calcium increase often manifests as a signaling wave that traverses the egg and releases it from meiotic arrest and metabolic dormancy.
