The clarity of lake water is affected by the amount of phytoplankton (marine plants), soil, clay, and other solids suspended in the lake. Suppose the concentration of carbon dioxide in the atmosphere
changed from 340 ppm to 380 ppm from 1980 to 2005. What effect would this have on the
occurrence of the full body plate trait? Explain your answer. Hint: Think about how carbon dioxide is
related to photosynthesis. (10 points)

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 last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).

it's a.true. i'm kind of smart.
