The correct answer is option B, that is, the release of large amounts of greenhouse gases can change Earth's climate.
Fossil fuels refer to hydrocarbons, mainly fuel oil, coal, or natural gas, produced from the leftovers of dead animals and plants. The use of fossil fuels has allowed large-scale industrial development and hugely supplanted water-driven mills, as well as the combustion of peat or wood for heat.
The burning of fossil fuels by humans is the biggest source of emissions of carbon dioxide that is, one of the greenhouse gases, which permits radioactive forcing and donates to global warming. One of the dreadful effects of global warming is the change in the climatic condition of Earth.

Answer:
Lactase
Explanation:
Lac operon (lactose) is degraded to glucose and galactose by three enzymes :beta galactosidase, galactoside permease and thiogalactosidase transacetylase.
<h2><u>Answer:</u></h2>
Fossil: is preserved pre historic life form present under ground at high pressure for a long time.Animal die and burried under layers of sediments.
It provides evidence about the history of life on earth. It also shows different groups of organisms, including species,that have changed over time. Because the formation of any fossil depends upon the precise combination of conditions.
As the world changes, plants and animals change with time . From fossils we compare organisms of modern time with ancient , the species we see today are very different from species that lived in the past. Thus, the fossil record can be used to show that organisms changed to meet new condition.
