Answer:
Some substance in the infectious S strain could change the harmless R strain into the more lethal form.
Explanation:
These first type of experiments where crucial to advance in DNA knowledge.
In one experiment, they treated the material with enzymes that destroy all proteins. This is important because scientist notice that there was something else that was causing the strain to change into a lethal form and was heritable (DNA). Know a days we know that plasmids are responsible for such transformation.
Answer: Anything living needs to have certain conditions, if for example a group of flightless birds who are adapted for warm weather had their environment get colder each year and more extreme the surrounding plants and other animals may have a difficult time surviving and this will cause the birds to have less food. The birds also will not be accustomed to these changes and will not be able to adapt their bodies fast enough. This also makes reproduction difficult and in turn further dwindles the population.
Hope this helps!

During the process of biological magnification , the concentration of pollutants, such as DDT or mercury, is multiplied as it passes up a food chain.
<span>Bryophytes</span> are more adapted for moist environments. This is due to the fact that they can live in water-filled places with mild temperatures.
