Drag the labels to the correct locations. The labels may be used more than once. Imagine that a space shuttle carrying astronauts is launched from Earth to the International Space Station (ISS). As the shuttle travels toward the ISS, it will encounter different layers of Earth’s atmosphere.

help Determine the change in temperature that the shuttle will experience while passing through each atmospheric layer.

temperature decreases with altitude
temperature increases with altitude

The hershey and chase experiments involved the preparation of two different types of radioactively labeled phage. which of the following best explains why two preparations were required? a. the bacteriophage used in the experiments was a t2 phage. b. it was necessary that each of the two phage components, dna and protein, be identifiable upon recovery at the end of the experiment. c. each scientist had his own method for labeling phage, so each conducted the same experiment using a different isotope. d. establishing the identity of the genetic material required observation of two phage generations.
