<h3>What is Bioremediation ?</h3>

A subfield of biotechnology called "bioremediation" uses living things like bacteria and microorganisms to clean up contaminated environments. It is used to clean up poisons, pollutants, and other contaminants from water, soil, and other habitats.

  • Bioremediation refers to the removal of biological fluids and blood that may include pathogens like hepatitis, HIV, and MRSA or pose other health problems. Crime scene cleaners employ enzyme cleansers rather than conventional cleaning products like bleach or ammonia to get rid of dangerous compounds from the site.

  • Microbial bioremediation, phytoremediation, and mycoremediation are a few of the most popular types of bioremediation.

The interaction between which protein and ion initiates muscle coupling?
labwork [276]

Answer:

Troponin and calcium ions.

Explanation:

Troponin is a component of thin filament along with tropomyosin and actin. It is a protein complex to which calcium binds and start the production of muscular force.

Calcium also playing a very important role in muscle contractions, it binds with troponin and helping to move tropomyosin.

When calcium ion attached to troponin, then conformational changes occurs in troponin shape and moves which allow tropomyosin going away from its inhibitory position from the myosin-binding sites on actin. After this, the energized myosin head starts binding to the actin molecules and starts the cross bridge cycle, which helping in shortening the muscle's fiber.

Which is true regarding diffusion and osmosis
BaLLatris [955]
“In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.”
