A substitution is a mutation that exchanges one base for another (i.e., a change in a single "chemical letter" such as switching an A to a G). Such a substitution could: change a codon to one that encodes a different amino acid and cause a small change in the protein produced. ... These are called silent mutations.
Answer:
Option (B).
Explanation:
Evolution is the process of the change of the species characteristics with the passage of time. The species that can adapt better in the environment has high chance of survival.
Human evolution has explained well in the evolution and involves human development from the ancestral primates. The human evolution has occurred at the short time might occur due to some genetic changes or mutation. The evolution of the human chromosome 2 has occurred in relatively short period of time. This shows that human have specific objectively measurable properties.
Thus, the correct answer is option (B).
Answer:The time growth between cell divisions is called interphase.
Explanation:
Because fish need light to see
I believe you're looking for "chemical digestion".
Chemical digestions is where food that we ate is digested into simpler and soluble molecules that can be absorbed by our body. Enzymes are used as a catalyst to speed up the reaction.
One example is the digestion of lipids. Enzyme named lipase is used to speed up the digestion of lipids into 3 fatty acid molecules and 1 glycerol. This way, our body can absorb these simple molecules, and use them in order to make our body function.
On the other hand, physical digestion does not include enzymes, such as chewing in our mouth, therefore, don't mix them up!
