What is the implication of a cell structure such as mitochondria or chloroplast having DNA?A. Because they were formed as a direct product of the nucleusB. Because they may have originated as their own form of ancient bacteria, eventually joining the cell structureC. Because the RNA often gets lost leaving the nuclear envelope, ending up in the mitochondria where it is converted back into DNAD. Because the mitochondria is the second biggest producer of DNA information apart from the nucleus

How does the polarity of a water molecule enable it to exhibit high surface tension?A. The hydrogen atoms form strong ionic bonds with oxygen atoms in other molecules.B. The non-polar nature of water allows it to spread easily and evaporate faster.C. The partial charges on water molecules lead to hydrogen bonding, which pulls water molecules tightly together at the surface.D. Water molecules have no charge, so surface tension is due to atmospheric pressure alone.

How do hydrogen bonds affect the amount of time it takes for water to heat up? A. Polar molecules have fewer hydrogen bonds which allows them to move quickly, causing them to slowly heat upB. Non-polar and polar molecules have the same amount of hydrogen bonds which causes them to slowly heat upC. Polar molecules have too many packed together which causes them to slowly heat upD. Polar molecules need hydrogen bonds to be broken up in order for them to heat up, which causes water to slowly heat upE. Non-polar molecules have hydrogen bonds that easily break up, which makes them heat up quickly compared to polar molecules
