The correct answer is option (d) atmosphere.
Fossil fuels are the hydrocarbons formed in the geological past, derived from the remains of dead plants and animals. They include the coal, fuel gas and the natural gas. The burning of fossil fuels is one of the greatest contributor of carbon dioxide being added to the atmosphere. This results in the pollution of air in the atmosphere resulting in the formation of smog. Carbon dioxide being a green house gas, affects the atmosphere and causes green house effect leading to global warming and climate changes.
The burning of fossil fuels affects the geosphere, biosphere and hydrosphere indirectly due to its primary direct effect on the atmosphere. Thus, atmosphere is directly affected by the burning of fossil fuels.
It would be A
First is: DNA > mRNA (messenger RNA) > tRNA (transfer RNA) > protein
"Viruses sometimes transfer information from RNA to DNA" is an exception to the <span>central dogma of molecular biology. The correct option among all the options that are given in the question is the first option or option "A". I hope that the answer has actually come to your great help.</span>
Answer:
c. 3, 5, 1, 4, 2
Explanation:
1. (3) food substance dissolves in saliva
2. (5) food substance enters taste pore and attaches to receptor on gustatory hair
3. (1) gustatory cell depolarizes
4. (4) neurotransmitter released by gustatory cell
5. (2) action potential stimulated in gustatory neurons
<em>Saliva has digestive functions that help food to be easily swallowed. We need saliva to taste foods because it dissolves the chemicals. The sense of taste is called gustation. We taste something with our tongue and then sensations would be carried via the facial (VII) cranial nerve. One of the newest taste to be described is umami. </em>
