Which could be the location where water emerges from the surface as a spring? 1 2 3 4

Step-by-step answer

P Answered by PhD

A spring is a natural discharge point of subterranean water at the surface of the ground or directly into the bed of a stream, lake, or sea. Water that emerges at the surface without a perceptible current is called a seep. Wells are holes excavated to bring water and other underground fluids to the surface.

A binary star system is made of stars, one of which is brighter than the other. Astronomers are able to detect the dimmer star because its gravity causes the bright star to . Astronomers can also spot the dimmer star by observing a phenomenon called a(n) binary. This happens when the dim star passes in front of the bright star.

Using the term water potential, explain why the onions ; (i)gained mass when soaked in dilute solutions of sodium chloride (ii)lost mass when soaked in concentrated solutions of sodium chloride

Step-by-step answer

P Answered by PhD

when soaked in dilute sodium chloride solution onion gain mass because of the process of osmosis.

Explanation: Osmosis is a process when there is movement of water from the region of comparatively higher concentration to the region of lower concentration across in a permeable membrane.
