The reason both of these are valid scientific hypotheses is because A) scientists with different educational backgrounds may put forth different hypotheses to explain the same data.
This approach in science is vital in making progress and has helped to explain many phenomena in the past. When scientists explain data using different approaches, they come to a more comprehensive conclusion.
Answer: False
Explanation: This is FALSE because the bats make a high frequency sound and we can't hear that type of sound.
Answer:
DNA plasmid that contains both "old" and "new" gene segments and confers new characteristics to the organism in which it is placed.
Explanation:
During the genetic engineering procedure, which aims at producing an organism with better and desirable characteristics, a DNA called PLASMID is usually used to convey the gene of interest into the organism.
A plasmid is a self-replicating extra-chromosomal DNA found in the bacterial genome. The plasmid becomes a RECOMBINANT PLASMID when a foreign DNA of interest is inserted into it, in order to act as a vector (carrier). Therefore, a recombinant plasmid is a DNA plasmid that contains both "old" i.e bacterial genome and "new" i.e foreign gene segments and confers new characteristics to the organism in which it is placed.
