Which of the following statements is false? the longer the chain length of a saturated fatty acid, the higher the melting temperature. some unsaturated fatty acids are liquid at physiological temperatures. most types of fat in many animals is used in energy production. the difference in melting temperature between a saturated fatty acid and an unsaturated fatty acid with the same chain length is only a few degrees c.

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 sex-linked recessive.

i just took the test

in a chemical reaction, the atoms and molecules produced by the reaction are called products. no new atoms are created, and no atoms are destroyed. in a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
