Answer:
C. They break down food materials into forms the cell can use.
Explanation:
Many scientists believe that RNA, or something similar to RNA, was the first molecule on Earth to self-replicate and begin the process of evolution that led to more advanced forms of life, including human beings.
The main causes of climate change are: Humanity's increased use of fossil fuels – such as coal, oil and gas to generate electricity, run cars and other forms of transport, and power manufacturing and industry. Deforestation
Volcanologists can predict eruptions—if they have a thorough understanding of a volcano's eruptive history, if they can install the proper instrumentation on a volcano well in advance of an eruption, and if they can continuously monitor and adequately interpret data coming from that equipment.
The hydrogen bond in polar molecules occurs only in compounds that have hydrogen bonded to N, O, or F.
These very highly electronegative elements create a partial positive charge on the hydrogen.
The H atom is attracted to the partial negative charge on an N, O, or F atom in another molecule.
The hydrogen bond is an attraction but not a true chemical bond such as ionic or covalent bonds. It is much weaker.
However, the hydrogen bond is a strong intermolecular bond.

<span>13.5%
Let's just add up the areas.
Left arm, front and back - 4.5% * 2 = 9%
from elbow to fingertips. So only half of the left arm is burned. so 9%/2 = 4.5%
Left chest and abdomen. Both the chest and abdomen are 9% each, but only half is burned. So (9+9)/2 = 9
So the total area burned is 4.5 + 9 = 13.5%</span>
