Answer:
An X-ray is done to diagnose the position of bones in the body whether its broken or not or in right place or not.
An X-ray machine is turned on to provide a visual of the bones showing bone condition. When the machine is turned on, X-ray travel through the body tissues, and due to the presence of calcium in bones, they absorb more X-rays, thus bones appear white against the black background of a radiograph.
These white bones on the radiograph will show the position of bones whether it's broken or not.
So, both the visuals that is X-ray and drawing showing visuals (the bones appear white) contribute valuable data to the given situation.
Answer: It is a technique used to amplify a segment of DNA of interest or produce lots and lots of copies. In other words, PCR enables you to produce millions of copies of a specific DNA sequence from an initially small sample – sometimes even a single copy. (looked it up on google lol)
Answer:
1) A nucleotide consists of a single sugar, a phosphate, and a nitrogen-containing base.
2) The monomer units of DNA are nucleotides, and the polymer is known as a "polynucleotide. Nucleotides don't have polymers because they are monomers.
3) They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell. The two main types of nucleic acids are DNA and RNA.
Explanation:
hope this helps!
Yes, because natural selection is when only those whose alleles are made for the organisms' fitness
