Answer:
A generalist species is able to thrive in a wide variety of environmental conditions and can make use of a variety of different resources. A specialist species can thrive only in a narrow range of environmental conditions or has a limited diet. Most organisms do not all fit neatly into either group, however
Explanation:
Answer:
Homeostasis is the ability to maintain a constant internal environment in response to environmental changes so organism must need it so they can be balanced internally in response to the environment .

Answer:
The correct answer is "the induced fit model".
Explanation:
The first model that looked to explain the enzyme and substrate interaction was the "lock and key" model. Although this model helped scientists to understand the specificity nature of the interaction enzyme-substrate, it does not reflect reality since enzyme was portrayed as a lock with a structure that doesn't change during the catalysis. Then half century later "The induced-fit theory" was proposed which fits much better the newer version of the enzyme action model. In this theory the enzyme is partially flexible and its structure changes as a result of its interaction with the substrate.
Answer:
Fossil is the name that is used for the trace or remains of an organism that lived long ago, most commonly preserved in sedimentary rock.
Explanation:
Fossils are the remaining parts of the organism's body which lives in ancient times and now they are extinct. Extinct means they are no longer the part of our earth or there is no specie of their kind. Fossil is only be found when the dead bodies of animals buried quickly so the chances of their complete decomposition is less and people will get it during digging after long time.
