Microorganisms participate in all the processes mentioned. All of the choices are correct
<h3>Economic importance of microbes</h3>
Microbes can be beneficial as well as harmful.
Some of the beneficial importance of microbes include:
- Production of medicine or medicinal products. E.g penicillin
- Conversion of atmospheric nitrogen to usable nitrogen forms to plants, otherwise known as nitrogen fixation.
- Food production. E.g yeast in the production of bread and Lactobacillus in the production of yogurts.
- Bioremediation of pollutants.

Every cell in the body is enclosed by a cell (Plasma) membrane. The cell membrane separates the material outside the cell, extracellular, from the material inside the cell, intracellular. It maintains the integrity of a cell and controls passage of materials into and out of the cell.
Answer: d. These filaments help the cell to withstand mechanical stress.
Explanation:
Intermediate filaments are the rope like fibers. These filaments form an extensive network ranging from the nucleus to the plasma membrane thus these filaments entirely cover the cytoplasma of the cell. These are developed from the cytoskeletal proteins. They have a diameter that is intermediate between thick and thin myofibrils. The diameter of the myofibril is in between 10 to 12 nm. They stabilize the nucleus. The main function of the intermediate filaments is to provide mechanical strength to the cells that will help them to withstand stress during stretching, elongation and changing shape.
Answer:
The arrangement of thin and thick filaments in myofibril.
Explanation:
Myofibril is defined as the basic rod like structure present in muscle cells. They are made up of long proteins including titin, actin, and myosin, and other proteins are helping them to hold together. The organization of these proteins are thin, and thick filaments which is known as myofilaments.
Thin filaments: Contains the actin protein which is coiled with filament nebulin.
Thick filaments: Contains the myosin protein. It is also known for force generation.
