For the polymerization of amino acids to form a protein, one would expect the entropy change in the reaction to be negative . this entropy change is expected because small monomers are joining to form polymer which decreases the degree of freedom.
Negative entropy change occurs when non-spontaneous change occur in the system. It means something which is more disordered will become less disordered hence energy will be required for the process.
As the monomers of the amino acids binds together to form a long polypeptide chain. It will lead to decrease in the degree of freedom of the amino acids molecule. Hence it can be called as negative entropy change.
Whenever monomers are joined together to form a macromolecule it will be show a negative entropy change.

The answer this this is A. Cell
The answer is (2) maintaining a stable internal environment.
Homeostasis is the process by which an organism tries to stabilise the internal body metabolism in response to external disturbances or changes. Example, when a person goes out into the snow, his body process will get overwhelmed by the sudden drop in the temperature. The body will try to stabilise its internal temperature by producing more heat in response to the cold exterior.
It has one very large moon that is almost half the planets size
so the answer would be A
Answer:
The correct answer would be "Birds and reptiles evolved from a common ancestor".
Homologous organs or structures refer to the set of organs or structure which are similar in internal structure but vary in their functions. The similar structure often demonstrates the common origin or ancestors.
Different organisms adapt to perform different functions as an adaptation against the varying environment.
For example, front limbs of reptiles and birds are similar in structure as they are made up of a similar set of bones, however, they differ in their functions due to adaptations against the varying environment.
