I think I'm sorry if it's wrong:(
In the electron transport chain. Oxygen is the electron recipient because it is a very strong oxidizing agent(very electronegative) and it keeps the chain going.
Biochemistry can be defined as the study of chemical compounds that occur in living organisms (plants and animals), and the vital processes that occur in their metabolism and catabolism. Biochemistry combines elements from both biology and chemistry and it involves the study of large biological molecules such as proteins, carbohydrates and lipids, nucleic acids and enzymes in terms of their interactions, functions and structures. Biochemistry can be divided into three disciplines which are; protein science, molecular genetics, and metabolism.
The answer which is false is, gene flow leads to divergence and the formation of new species.
What is speciation?
For speciation to occur two populations must be prevented from interbreeding.
This means that populations must become isolated from on another through the geographical or biological barriers.
If populations remain isolated long enough, speciation will eventually occur because of changes accumulated in population due to natural selection.
What is gene flow?
Geographical isolation hampers gene flow because of spatial separation which in turn leads of reproductive isolation due to the inability of meeting gametes to leads.
It causes genetic drift due to the barrier of gene flow between them and parent species.
Certain alleles get fixed into population due to inbreeding in a smaller population while other gets eliminated, this leads to formation of new alleles and new gene pool, so-called progressive genetic divergence.
Finally there is the formation of new species when genetic variation are accumulated for several generations.

Answer:
Amino acids contain nitrogen; fatty acids and sugars do not.
Explanation:
Genetic material is made of nucleotides, which contain amino acids; fatty acids and sugars are not part of genetic material. - this is false. Genetic material is made of nucleotides, but they are made of a sugar, phosphate group, and a nitrogenous base. Genetic material is transcribed then translated into a string of amino acids called a polypeptide chain.
Amino acids are building blocks to larger molecules; fatty acids and sugars are not. - false, amino acids are building blocks to larger molecules called proteins However, sugars are also building blocks for polysaccharides like starch, and fatty acids can combine to form triglycerides
Amino acids contain nitrogen; fatty acids and sugars do not. - this is true. Fatty acids and sugars are made of carbon, hydrogen, and oxygen. Amino acids contain carbon, hydrogen, oxygen, and nitrogen. They also sometimes contain other molecules in their R groups e.g. Sulphur.
Amino acids make up proteins, which provide energy for the body; fatty acids and sugars do not provide energy. - this is false, fatty acids and sugars can also provide energy
