The body gets energy from some compounds.

Some compounds determine physical characteristics.

Options 2 and 3.

Explanation:

Organic compounds basic to human working incorporate sugars, lipids, proteins, and nucleotides. These mixes are said to be natural since they contain both carbon and hydrogen.

There are four main types, or classes, of organic compounds found in all living things: carbohydrates, lipids, proteins, and nucleic acids. In addition, there are other organic compounds that may be found in or produced by some organisms.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
