The stability of atoms depends on whether or not their outer-most shell is filled with electrons. If the outer shell is filled, the atom is stable. Atoms with unfilled outer shells are unstable, and will usually form chemical bonds with other atoms to achieve stability.
Answer:
C). Buffers
Explanation:
The given analogy can best be completed with 'buffers' as it similarly compares with the 'solution pH' like the comparison between 'shock absorbers' and 'vehicle movement.' <u><em>Like the 'shock absorbers' function to help in improvising the vehicle movement and ride quality by lowering the effect reverberations of traveling on a rough platform, similarly, the 'buffers' help in regulating the 'pH of a solution.</em></u>' Thus, <u>option C</u> is the correct answer.

Answer:
b. All three plants have a common ancestor that had leaves.
Explanation:
Starch is a polymer composed of glucose units as monomers. Hydrolysis reaction can break down large molecules into smaller ones.
- Hydrolysis is a type of chemical reaction in which a water (H2O) molecule is used to break down large molecules into smaller ones.
- Starch is a complex polysaccharide composed of more than six (6) glucose molecules linked by alpha-glycosidic bonds.
- Glycosidic bonds can be hydrolyzed by specific enzymes known as glycosidases.
- A starch molecule composed of 300 glucose molecules contains 299 alpha-glycosidic bonds.
- In consequence, in this case, 299 water (H2O) molecules are required to completely hydrolyze the amylose starch polymer into glucose monomers.
