The three components of the nucleotides are phosphate groups, deoxyribose sugar, and a nitrogenous base.
When water reaches Earth's surface, it can become groundwater, accumulate in bodies of water, or evaporate into the atmosphere.
When water reaches Earth's surface, it can undergo several processes. First, it can soak into the ground and become groundwater, which fills up spaces in soil and rocks. Second, it can accumulate in bodies of water like lakes, rivers, and oceans. Finally, some of the water can evaporate back into the atmosphere, where it will eventually condense and form clouds, leading to precipitation and the water cycle.

All Eukaryotic cells contain small bodies known as Centrioles
B.They all contain the same DNA but they express different genes.
C.They can turn into whatever type of cell your body needs to ensure survival.
D.Each cell can perform various functions for maximum efficiency.
E.There are no more than 200 types in the body or else there would be too many to maintain.
Answer:
B
Explanation:
All cells contain the same DNA, but there regulators that control which genes are expressed in the cell
The levels of organization from smallest to largest in living organisms are: atoms, molecules, cells, tissues, organs, organ systems, and organisms. Each level is more complex and is made up of the previous level.
Living organisms are highly structured and follow a fall in organization from smallest to largest. The smallest and most fundamental unit of matter is the atom, which consists of a nucleus surrounded by electrons. Atoms form molecules, where a molecule is a chemical structure consisting of at least two atoms held together by a chemical bond. Some biologically important molecules are macromolecules, which are large molecules typically formed by combining smaller units called monomers.
At a higher level of organization, molecules combine to form cells, which are the basic unit of life. A group of cells that work together to perform a specific function is called a tissue. Several tissues combine to form an organ, such as the heart or liver. Multiple organs then work together in an organ system, like the digestive system or circulatory system. Finally, all the organ systems in the body combine to form a complex living organism, such as a human. Thus, the levels of organization from smallest to largest are: atoms, molecules, cells, tissues, organs, organ systems, and organisms.

Answer:
The central dogma of molecular biology explains the flow of genetic information, from DNA ?to RNA?, to make a functional product, a protein?.
The central dogma suggests that DNA contains the information needed to make all of our proteins, and that RNA is a messenger that carries this information to the ribosomes?.
The ribosomes serve as factories in the cell where the information is ‘translated’ from a code into the functional product.
The process by which the DNA instructions are converted into the functional product is called gene expression?.
Gene expression has two key stages - transcription? and translation?.
In transcription, the information in the DNA of every cell is converted into small, portable RNA messages.
During translation, these messages travel from where the DNA is in the cell nucleus to the ribosomes where they are ‘read’ to make specific proteins.
The central dogma states that the pattern of information that occurs most frequently in our cells is:
From existing DNA to make new DNA (DNA replication?)
From DNA to make new RNA (transcription)
From RNA to make new proteins (translation).

Reverse transcription is the transfer of information from RNA to make new DNA, this occurs in the case of retroviruses, such as HIV?. It is the process by which the genetic information from RNA is assembled into new DNA.
Does the ‘Central Dogma’ always apply?
With modern research it is becoming clear that some aspects of the central dogma are not entirely accurate.
Current research is focusing on investigating the function of non-coding RNA?.
Although this does not follow the central dogma it still has a functional role in the cell.
