Meteoroids are small objects in space, usually made of rock or metal. These bodies often get close to a planet and fall through its atmosphere. A burning streak of light, called a , is visible as it falls through the sky. Sometimes the object does not burn up completely and a part of it survives the fall to the planet’s surface. These rocky bodies, called , are studied by scientists to gain a better understanding of our solar system.

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.

currents is the correct answer.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
