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:
Shear stress
Explanation:
Shear stress is a type of stress that occurs when a rock mass is pushed in parallel and opposite directions.
Summer
, for the northern hemisphere, summer is the warmest time of year. It's not because the planet is that much closer to the Sun, it's because the top part of the Earth is facing the Sun for a amount of time.
The Sun is directly over the Equator during the autumnal equinox, and heating the northern and southern hemispheres equally. As the northern hemisphere is moving towards shorter days and the cold winter, the southern hemisphere is watching the snows melt and the flowers bloom during their spring.
Summer is the season where the Earth is tilted way from the Sun and the South Pole is getting all of the light
Spring is a bit of a mirror image to our position in autumn. The Sun is directly over the Equator during the equinox and the northern and southern hemispheres
Answer:
Thousands of species is an example of biodiversity.
<u>Explanation:
</u>
<em>Biodiversity is the short term for biological diversity which was coined by E.O. Wilson</em>. <em>Biodiversity refers to all the species of plants (flora) and animal Kingdom (fauna) present on the Earth.</em> It covers different types of ecosystems present in a well-defined area whether it be terrestrial or aquatic and the genetic variability within a species.
The variety of crops and livestock present on Earth have played a great role in human development. Without them, life would not be possible. That’s why it is our moral duty to conserve our biodiversity. If we preserve it for our future generations, we will survive. If they are overused or misused, the entire food chain would perish.
I believe the answer is littoral zones.
Sorry if I'm wrong, Hope this helps.
