The bones in the front limbs of many mammals are similar in their structure and arrangement. What term is used to
describe physical similarities between related species that indicates a common ancestry

Homologous

Explanation:

If two or more species share a unique physical feature, such as a complex bone structure or a body plan, they may all have inherited this feature from a common ancestor. Physical features shared due to evolutionary history (a common ancestor) are said to be homologous.

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."

b. read the phase at the intersection of any given temperature and pressure.
