The group of chemical processes in organisms that maintain life is known as metabolism. The three primary functions of metabolism are: converting the energy in food into energy that can be used to power cellular functions.
It is convenient to divide metabolism into two groups: Molecules are broken down during catabolism to provide energy. All of the substances that the cells require are synthesised during anabolism. Metabolic processes include the chemical reactions that keep you alive. One example of metabolism is the rate at which you burn fat and consume calories. the constant anabolic and catabolic chemical and physical processes that occur in living things and their cells. Specific areas of the cell host metabolic events. The cytoplasm is where amino acid degradation and some phases of glycolysis, fatty acid synthesis, and glycogen synthesis take place. Within mitochondria, certain metabolic pathways are located at particular points.

A point mutation is a mutation that affects only a single nucleotide of a nucleic acid. They involve substitution of one base for another which changes the complementary base as well in DNA, they may also involve insertions and deletions of a single base pair. I therefore think the point mutations in a DNA sequence may profoundly have an effect on the synthesis of proteins, or may also have no effect on protein synthesis at all. These mutations can be beneficial to an organism, however they are more commonly neutral or harmful.
Answer:
Cilia /flagella aids in movement.
Explanation:
Cilia and flagella helps in cellular movement.Bacteria contain flagella which helps in the propelling of bacteria towards nutrients or away from the waste materials.On the other hand cilia are threadlike appendages that helps in the attachment of bacteria to solid surface.
In human body respiratory system contain cilia which help to move mucus ,dust,germs and polens out of the body.
The tail of human sperm contain flagella which helps in the in the swimming of sperm inside the ovary in search of an egg.
Answer:
Protein evolution is inescapably tied to changes and selection of DNA polymorphisms and mutations because protein sequences change in response to alterations in the DNA sequence.
Amino acid sequences and nucleic acid sequences do not mutate at the same rate.
