Answer:
c silent mutation
Explanation:
The given mutation changes the genetic code "GGC" to "GGA". According to the genetic code table, both "GGC" and "GGA" code for glycine. Since both mutated and normal codon code for the same amino acid, that is glycine, the mutation would not have any effect on the function of the gene.
The point mutation that does not affect the function of a gene is called a silent mutation. Hence, the given example represents the silent mutation.
The question is incomplete as it does not have the options which are:
A. bioremediation
B. mutualism
C. quorum sensing
D. quorum settling
E. mass-settling
Answer:
C. quorum sensing
Explanation:
Quorum sensing is the gene regulation mechanism used by the bacteria to communicate with the other bacteria. The quorum sensing process depends on the number of bacterial cells or the density of the cells.
When the bacterial number increase in number then the bacterial cells send the signal to the nearby cells and and regulates the expression of the gene. In the given question, the same chemical signal process depends on the density of the cell and thus quorum sensing is correct.
Explanation:
Macromolecules are molecules of large number of atoms usually with a diameter ranging from about 100 to 10,000 angstroms.
Unicellular organisms
Explanation:
Unicellular organisms typically respires faster to release energy.
Respiration is a gaseous exchange between cells and the environment. Here, oxygen is taken in by the cell and carbon dioxide is the by product of the metabolic process.
- Unicellular organisms will respire faster because they are at the lowest level of organisation.
- The cells are in direct contact with the environment.
- They do not require special set up to obtain and circulate oxygen in them.
- The waste of the metabolic process is also discarded easily and very fast.
- Organisms at lower levels of organisation typically have a faster rate of respiration.

Answer:
Food webs either start with producers on<u><em> land </em></u>or with producers in <u><em>water</em></u>.
Explanation:
A food chain or a food web will always start with a producer and always end with a type of consumer. This is because producers are organisms which have the ability to make their own food. They are mostly plants or other producers like algae. Both aquatic and land food chains or food webs will start with a producer. An aquatic food web will generally start with a producer present in water. A land food web will mostly start with a producer from the land.
