The sugar glider in Australia and the flying squirrel in North America are both small mammals with large expanses of loose skin
Flauer [41]

Answer:

Each have adapted in very similar ways to similar habitats.

Explanation:

According to Darwin, given a similar set of conditions, two different organisms can adapt in the same direction. Here, the sugar glider inhabits Australia and the flying squirrel inhabits North America. There is a huge distance between their locations and also they are two different species with no direct evolutionary relation. However, because of the similar conditions present in their habitats, they developed same traits over the time. Both of them live in forested areas so they developed loose skin between their limbs which allowed them to glide freely between the trees.

Compare hypertonic, hypotonic, and isotonic solutions. When an environment is hypotonic, what happens to the cell?
algol13

When an environment is hypotonic, the cell has more solute so solvent move from outside the cell to inside causing the cell to swell.

WHAT IS TONICITY?

  • Tonicity is the ability of a solution to induce water loss or water gain in a cell. A solution can either be; hypertonic, hypotonic or isotonic

  • A hypertonic solution has more concentration of solute than its surroundings while a hypotonic solution has less concentration of solute compared to it's surroundings.

  • If a hypotonic solution has less solute, this means that it will have more solvent (water). Based on the principle of osmosis, water moves from a region of high concentration to region of low concentration.

Hence, water will move into a cell that is located in a hypotonic environment, causing it to swell.
