Answer:
In terms of adaptation, fitness refers to the ability of an organism to survive and reproduce in a constantly changing environment.
Adaptive traits are very much important in a constantly changing environment as they increase the chances of survival of a population in the environment.
For example, Darwin's finches adapted to develop different types of beaks in order to get nutrition in different environments. Long necks of giraffes are also considered as a result of adaptation which helps them get the food located high on trees.
A prothallium, or prothallus<span> is usually the </span>gametophyte<span> stage in the life of a </span>fern<span> or other pteridophyte. Occasionally the term is also used to describe the young </span>gametophyte<span> of a liverwort or peat moss as well.</span>
Answer:
Function will be disrupted by adding the urea and regained by removing the urea.
Explanation:
The protein is one of the important biomolecule made of the polymers of the alpha amino acids that are linked together by peptide bonds. The protein works at their specific pH.
Denaturants disrupt the 3 dimensional structure of protein that affect their normal functioning. In the given experiment, the urea acts as denaturant and disrupt the protein structure. The removal of urea will reverse the denaturant condition and protein gain its function.
Thus, the correct answer is option (a).
I believe that this is true
A catalyst works by providing an alternative reaction pathway to the reaction product. Furthermore the rate of reaction is increased.
