Ribonucleic acid, the basic unit of RNA, has a hydroxyl (-OH) on the second carbon atom. On the other hand, the deoxyribonucleic acid, the basic unit of DNA, has a single hydrogen in the second carbon. This chemical structure difference makes RNA heavier than DNA due to the extra carbon atom.
The RNA/RNA-DNA hybrids can be separated from double-standard DNA using a high-resolution centrifuge due to this difference in weight. The image belows shows the extra oxygen atom in the 2' carbon
Answer:
A) unsaturated fatty acids
B) omega-3 fatty acids
C) saturated fatty acids
Explanation:
Monounsaturated fat — found in olive, peanut and canola oils — is a healthier option than is saturated fat. Nuts, fish and other foods containing unsaturated omega-3 fatty acids are other good choices of foods with healthy fats.

An increase in food and a decrease in predators would most likely genetic Variation in a population.
It is a change of frequency in a genes variant which is called genetic drift. this kind of scenario will result to smaller large population and larger small population
A variable is part of an experiment that can change, such as amount of light, temperature, humidity, time changes, or plant growth.
In an experiment, an independent variable is a variable that either changes on its own, or you purposely change it.
The goal of an experimental investigation is to determine how changes in an independent variable affects another variable, which is called the dependent variable.
Remember: When designing an Experimental Investigation it is important that you only have one independent variable and one dependent variable. All other variables must be controlled, meaning they must stay the same.
Climates near bodies of water in general are more balanced because water can take in heat from its surroundings and give off heat when it is cold. This is due to its extremely high specific heat. So I think ocean water can impact local climates because of its thermal energy. This is an educated guess though.
