The correct answer is D), because, as he is throwing the ball, the potential energy, that was stored in the ball, changes into kinetic energy, but there is no energy increase or decrease.
The material that are used by biotechnologists would be C. Restriction endomuclease. These are specialized group of enzymes that can cleave or break multiple phosphodiester bonds between DNA sequences.
First pass metabolism of a drug is said to occur when the concentration of a drug that is administered orally is significantly reduced before it reaches the systemic circulation.
First pass metabolism usually occur in the liver.
The routes of drug administration that avoid complete first pass metabolism are: sublingual, transdermal, rectal and inhalation.
Answer:
The correct answer would be the harmless bacteria had been transformed.
Griffith used two different strains of the bacteria <em>Streptococcus pneumoniae - </em>type-III-S or smooth strain and type II-R or rough strain.
Smooth strain had protective covering around itself (protect itself from hosts's immune system) and was able to kill the mice.
Rough strain did not have any protective covering around itself and thus could be easily removed by the immune system Hence, it was not able to kill the mice.
In addition, heat killed smooth strain was also not able to kill the mice. However, when remains of it was added with rough strain then the blend was able to kill the mice.
Lastly, he was able to isolate living bacteria of both the strains.
He concluded that non-lethal type II-R strain was transformed into lethal type II-S strain by "transforming principle" (which we know today as DNA) that was supposed to be the part of dead III-S strain bacteria.
