Answer:
Just by the way they look.
Explanation:
They have the same kind of bone structure, and the only real difference would be in size/shape of the bones, and the color of the fur.
Answer:
Grinnell was the scientist who coined the term niche. An ecological niche the place where the species and their members live together. Niche is quite different from habitat.
Niche include all the things which have impacts on a population and population impact on its environment and other species in their area. So the ecological niche does not mean the volume of area a species occupies but also include its specific functional role in its community.
For example, a lake can be considered as a habitat for fish but a lake can provide a different niche for fishes. A big fish hunting a small fish in a portion of a lake is a niche and a small fish hunting an insect in another portion of the lake is another niche.
Answer:
A. The catalytic activity of the complex is enhanced by the protein component and completely dependent on the RNA component of the complex.
Explanation:
RNAses are enzymes that degrade RNA. When treating the complex with an RNAse, the catalytic activity is completely abolished. This tells us that the RNA component is indispensable to the catalytic activity of the complex.
Proteases are enzymes that degrade proteins. Treating the complex with proteases only decreases slightly the catalytic activity, but it does not abolish it completely. This tells us that the protein component of the complex enhances the catalytic activity, but without it the complex can still work.
Those volcanoes are called seamounts. Seamounts arise in ocean seafloor. They rise at least 1000 meters, so seamounts can be found in deep sea. Most of them are made during volcanic processes.
