Oxygen-16 atomic number is 8 so it has 8 protons. Its atomic weight is 16 so 16-8 = 8 neutrons.
In organic molecules, the atoms are linked by covalent bonds. Organic molecules are generally large and may be complex, involving many such bonds. Inorganic compounds have considerably simpler structure in terms of number, but not necessarily type, of bonds. In organic molecules, to a first approximation, we may say that one bond does not affect another. Thus an atom such as a chlorine atom, -Cl, or a group of atoms such as the alcohol group, -OH, on one end of a molecule will behave chemically in the same way almost without regard to the molecule to which it is covalently attached. The idea of different independent or semi-independent atoms or groups of atoms on the same molecule is central to our modern understanding of organic chemistry. It is called the concept of functional groups. The nomenclature of organic compounds, like most of the rest of our understanding of reactions of organic compounds, is based upon the concept of functional groups.
Answer:
D. Community C has a greater species population than Community B and A.
Explanation:
Community C total population: 98
Community B total population: 62
Community A total population: 24
Answer:
Option C
Explanation:
Primase synthesizes DNA polymerase through the initiation of synthesis of RNA primer. DNA polymerase is able to add nucleotides in only one direction towards the direction of replication fork Hence, it add to the chain only at 3’ end and build new strand from 5’ to 3’ end.
The 5’ to 3’ strand is the leading strand and is easy to build as 5’ to 3’ progresses towards the replication fork and DNA polymerase also move in the same direction
Hence, option C is correct
