25 points plz (biology honors-high school) 18. sam’s mother has type o blood. her father is type b blood, with the genotype bo. what are the possible blood types that sam could have? (use scratch paper to make a punnett square)

wouldnt it be the scientific method?

explanation:

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.

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 is the correct answer
