Answer:
So, Mechanical and Chemical Digestion is the way of breaking down foods in the body. The difference between Mechanical and Chemical Digestion is, Mechanical Digestion involves the body's movement to make the food smaller and Chemical Digestion involves enzymes to break the food down.
Explanation:
Since Mechanical Digestion involves moving around to break the food down, you would get up and walk around a little to burn it to make it work and Chemical Digestion is just using the natural enzymes in the body to break food down.
Answer: Meselson & Stahl reasoned that these experiments showed that DNA replication was semi-conservative: the DNA strands separate and each makes a copy of itself, so that each daughter molecule comprises one "old" and one "new" strand. The semi-conservative model, in which each strand of DNA serves as a template to make a new, complementary strand, seemed most likely based on DNA's structure. ... From the patterns of DNA labeling they saw, Meselson and Stahl confirmed that DNA is replicated semi-conservatively.
Explanation:
1. Two genetically identical copies of DNA
2. Finds an error in DNA, removes the incorrect nucleotide and replaces it with a correct one.
3. It is used as a copy/ "template" for replication in order to have two identical copies of DNA.
4. DNA helicase unwinds DNA double helix and Topiosomerase ensure there isn't too much unwinding.
5. Replication has a built on proofreading system - DNA polymerase removes the incorrect nucleotide and replaces it with a correct one.
