Answer:
Cohesive forces are responsible for surface tension, a phenomenon that results in the tendency of a liquid’s surface to resist rupture when placed under tension or stress. Water molecules at the surface (at the water-air interface) will form
Adhesion and cohesion are water properties that affect every water molecule on Earth and also the interaction of water molecules with molecules of other substances.

To prove that a certain fruit (in this case, an orange) indeed contains a certain compound (in this case, vitamin C); then the vitamin C should be extracted and isolated from the orange and must be confirmed by molecular analysis. The extraction process involves using chemicals (i.e. 6% MPA), and procedures such as centrifugation and filtration. Then the extract is stored and subjected to high-performance liquid analysis (HPLC) to measure the vitamin C content.
Answer:
Dehydration
Explanation:
What causes bacteria to die in an extremely salty environment is dehydration due to the loss of osmotic balance in their cells.
Water molecules would normally move from the region of high water potential or low solute concentration to the region of low water potential or high solute concentration through a biologically permeable membrane.
<em>An extremely salty environment would be hypertonic to the cells of bacteria and the cell walls of bacteria act as biologically permeable membranes. Hence, the bacteria cells lose water due to the osmotic movement of water from their cells to the surrounding salty environment. </em>
