BaLLatris [955]

A hypertonic solution has:

Fewer water molecules outside the cell than are inside the cell. Thus, option "A" is correct.

<h3>What is hypertonic solution?</h3>
  1. The cell is in a hypertonic solution because it lost water through osmosis and shrunk.
  2. A hypertonic solution contains more solute molecules compared to solvent molecules while the hypotonic solution has more solvent molecules than solute molecules.
  3. When a plant cell is placed in a hypertonic solution it loses water through osmosis and shrinks.
  4. An animal cell placed in a hypotonic solution absorbs water through osmosis, increases in size and then bursts. Plant cell, on the other hand, does not burst when placed in a hypotonic solution as it contains a cellulose cell wall.

Thus, option "A" is correct.

LUCKY_DIMON [66]

<u>The illegal wildlife trade </u>or <u>wildlife trafficking</u> is the commercial process that involves the trade of non-domestic species (animals or plants), or in some cases certain parts of individuals. These species are rare and endangered and thus this practice is harmful and represents an increasing dangers of extinction.

This practice is highly illegal, but unfortunately, at the same time, due to the rarity of the species highly profitable. Efforts are made globally to stop this practice and to avoid the extinction of many endangered species.
