The correct answer is: Even though the S strain had been heat-killed, it changed the R strain.
Griffith in his experiment used two strains of bacteria:
• The rough strain (R) which did not cause pneumonia, (nonvirulent)
• the smooth strain (S) which did caused pneumonia (virulent)
When Griffith heat-killed the S strain it did not caused mice to die.
But, when he gave both the heat-killed S strain and the R strain to mice, the mice developed pneumonia and died.
Griffith conclusion was that the R-strain bacteria took what he called a "transforming principle" from the heat-killed S bacteria which transformed the nonvirulent R strain.
There are kingdoms and the kingdoms represent different organisms.
Hubble's Law is the recessional velocity, which is the speed of a celestial body moving away from the observer, is proportional to its distance.
It states The Universe is expanding, our galaxy is expanding, red shift is proportional to a body's distance from us, and red shift is proportional to distance form the center of the universe.
Answer:
True
Explanation:
Usually, dominant traits will show more often because they are, well, dominant. For example, BB and Bb would both show up with dominant traits. It would be required for all lowercase bs in order for a recessive trait to be seen.
