It's the last one."This is a result of anaerobic respiration".
The body of Micro class species like bacteria is formed of a single cell; these organism are described as unicellular. In a unicellular organism, all life activities are carried out by itself with its internal structures.
The intracellular structures are called the organelles. These apecies generally live for a short life span because of all the ondependant effort to survive. An injury can cause death to this organism
In the vast majority of plants and animals, the body is made up of numerous cells. They are called multicellular organisms. A multicellular organism is actually an aggregation of cells.
Here a group of cells functions in a same way to form a tissue or an organ (Example: Xylem vessels, cork cells, cells in the skin).
Multicellular organisms have a great capacity to survive than unicellular organisms. They live for a long span of time and injury or death to some cells does not cause immediate consequences as the cells can easily be replaced
Answer:
B.
Explanation:
The movement of substances(ions and molecules) against their concentration gradient is called Active transport.Since these substances are moving against whew they are already in abundance,extra energy is needed for them to move against this gradient.Therefore,ATP.,oxygen is needed by the cells undergoing this transport process to transfer substances into the cells.
It is useful for entry of substances in plants e.g glucose,and for transport of materials in intestine in man
Na-K pumps, exocytosis,endocytosis are examples of this transport process.
It is inhibited by lack of oxygen,cyanide etc.
