Suppose that scientist discover a planet orbiting a star within its life zone what else might scientist want to knowbefor concluding that this planet could support earth like life forms

A scientist might also want to know if there is water, a sustainable atmosphere, or the temperature on the planet. If any of these features are different, then life may not be sustainable.

There is no possible explanation as this is practically definition.

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 answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
