Explanation:
Chemical reactions are also referred to as chemical change. A chemical change often leads to the formation of new substances and is not easily reversible.
A chemical reaction may be accompanied by the emission of heat and light, formation of a precipitate, evolution of gas, or a color change.
These observable physical effects may tell us weather a chemical reaction has taken place or not so we have to observe the system closely for any of these effects stated above.
Cellular differentiation<span> is the normal process by which a </span>cell<span> becomes increasingly specialized in form and function. The classic </span>example<span> is the process by which a zygote develops from a single </span>cell<span> into a multicellular embryo that further develops into a more complex fetus.

Answer: Option (d) is the correct answer.
Explanation:
A reaction in which there occurs change in oxidation state of reacting species is known as an oxidation-reduction reaction.
(a) 
Will be written as:
In this reaction, there occurs no change in oxidation state of reacting species. Hence, it is not an oxidation-reduction reaction.
(b) 
Will be written as:
Similarly here, there occurs no change in oxidation state of reacting species. Hence, it is not an oxidation-reduction reaction.
(c) 
Will be written as:
Here, also there occurs no change in oxidation state of reacting species. Hence, it is not an oxidation-reduction reaction.
(d) 
So, here there occurs change in oxidation state of Mg from 0 to +2 and oxidation state of H changes from +1 to 0. Hence, it is an oxidation-reduction reaction.
Thus, we can conclude that is an oxidation-reduction reaction.
Answer:
A. All sites B. A site C. E site D. P site
Explanation:
A. Because all sites consequently take place while peptide is synthesized.
B. A site (aminoacyl site) is called so because it binds to charged aminoacyl peptide.
C. Because it is the exit site and it takes the final stage on the uncharged molecule.
D. The P site (peptidil site which takes main role in peptide synthesis.
