Imagine a new object is discovered in the solar system. it is orbiting the sun at the distance of 2.8 au. the object is known to be of sufficient mass to be spherical in shape. would this object be classified as a planet or a dwarf planet?

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.

the real answer is b. scintillation counter

i am sorry but i need more information and a picture.

plants absorb water from the soil by osmosis. root hair cells are adapted for this by having a large surface area to speed up osmosis. the absorbed water is transported through the roots to the rest of the plant where it is used for different purposes: it transports dissolved minerals around the plant.
