Answer:
The functional groups that define the two different ends of a single strand of nucleic acids are:
B. a free hydroxyl group on the 5' carbon a free hydroxyl group on the 3' carbon
G. a free phosphate group on the 5' carbon
Explanation:
A nucleic acid is a polymer formed of nucleotides that are linked with a phosphodiester bond. The structure of a nucleotide consists on a phosphate group linked to a pentose (ribose in RNA and deoxyribose in DNA) that is also attached to a nitrogenous base. The nitrogenous bases are adenine, guanine, cytosine, thymine (in DNA) and uracil (in RNA).
DNA and RNA are nucleic acids which can be found in a double or single strand presentation.
Nucleic acids are synthesize in the 5’ to 3’ direction, so that is why the convention is that the sequences are written and read in that direction.
The strand of a nucleic acid is directional with an end-to-end orientation, where the 5’ end has a free hydroxyl or phosphate group on the 5' carbon of the terminal pentose, and the 3’ end has a free hydroxyl group on the 3’ carbon on the terminal pentose (ribose/ deoxyribose).
Answer:c. one fact about a person or an item.
Explanation:
Database table is is made up of fields. A field is simply a data structure for a type-single piece of data.
Fields can be organized into what is known as records, which is one that contain all the information that (groups of the) table entails relevant to a specific entity in context.
Answer:
Twins occur.
Explanation:
If the embryo is divided into half by artificial methods such as microsurgical, twins occur in the female body. Both the embryo are identical to each other. twins means that there will be two babies formed at the same time in the body of female. After the separation of embryo, both the embryos are genetically identical to each other and it continue to develop into a new organisms.

1. Evaporation - During this process, surface water turns into water vapor. This is done by the transfer of heat energy. Water absorbs this heat energy and turns into its gaseous state.
2. Condensation - Water vapor rises into the atmosphere and is changed into water droplets. When gas is chilled, it turns back into a solid state. These water particles that form in the atmosphere then come together to form clouds.
3. Sublimation - Ice directly converts into water vapor without first converting into a liquid. This process accelerates when the temperature is low or pressure is high.
4. Precipitation - It is the result of evaporation and condensation. Precipitation describes any liquid or solid water that falls to Earth as a result of those two processes. It includes rain, hail, snow, sleet and a bunch more.
5. Transpiration - When precipitation happens, the soil absorbs some of the water. While in the soil, the roots of plants will take in the water and push it towards the leaves where it is used for photosynthesis.
6. Run Off - This happens as a result of precipitation, so it is again, technically not a process. As water pours down, it leads to runoff. This is the action of water running over the surface of the Earth. As water runs over the ground, it can displace the topsoil with it and move minerals along lakes, seas and oceans.
7. Infiltration -
This last process happens when water does none of the things stated above after precipitation. Sometimes, some of the water will move deep into the soil. Avoid the plants, avoid evaporation, avoid runoff, everything. The water instead seeps down and increased the level of the groundwater table. It is called pure water and is 100% fresh and drinkable.
