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 carbon dioxide produced as a result captures the heat in the surrounding atmosphere and causes a rise in temperature. Recently, it has been observed that the glaciers are melting and each year the net temperature of the core of the Earth is increasing.

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.

JulijaS [17]

If the larva had one head at the posterior pole, it would be normal. The larva would have two heads, one at the front of its body and the other in the center.

What is bicoid mRNA?

When translated, bicoid protein forms a morphogen gradient that shapes the embryo's head and thorax if bicoid mRNA localizes to the anterior of the Drosophila egg.

How does the egg's bicoid RNA influence development?

According to recent research, Bicoid specifies the anterior of the Drosophila embryo in two different ways. It initially suppresses posterior development. It accomplishes this by attaching to and preventing caudal RNA, which is distributed throughout the egg and early embryo, from being translated.
