A and B are solutions of salt dissolved in water that are separated from each other by a semipermeable membrane in each scenario

. Water can pass through this membrane, but the salt cannot. Match each pair of solutions to the net direction the water will flow between the two solutions.
Net flow toward solution A Net flow toward solution B No net flow
solution A: 14% salt solution solution B: 1% salt solution solution A: 5% salt solution
solution B: 5% salt solution solution A: 4% salt solution solution B: 13% salt solution

Answer:

<u>solution A: 14% salt solution solution B: 1% salt solution:</u> net flow towards solution A.

<u>solution A: 5% salt solution  solution B</u>: 5% salt solution: no net flow

<u>solution A: 4% salt solution solution B</u>: 13% salt solution: net  flow towards solution B.

Explanation:

<em>This is a simple case of osmosis - the movement of water molecules of the region of lower concentration of solute to the region of higher concentration of solute through a permeable membrane. </em>

The net movement of water will always be towards the solution with higher salt concentration. Hence;

  • <u>solution A: 14% salt solution solution B: 1% salt solution:</u> net movement of water would be towards solution A.
  • <u>solution A: 5% salt solution  solution B</u>: 5% salt solution: no net movement
  • <u>solution A: 4% salt solution solution B</u>: 13% salt solution: net movement of water would be towards solution B.

Did the Florida Panther become endangered because of natural selection, genetic drift, or gene flow?
Natalija [7]

Answer:

ALL OF THE ABOVE

Explanation:

Genetic Drift are the changes in allele frequency of a population that result from RANDOM survival or reproduction of individuals with certain characteristics.  Survival or reproduction of those individuals in the face of some environmental change is a matter of LUCK or CHANCE, not because of their phenotype or genotype.

While in Natural selection, the environmental events that affect a population are likely random, but the survival or reproduction of the individuals depends on their phenotypes and genotypes.

Meanwhile, Gene flow is the movement of genes into or out of a population. Low gen flow can lead to low genetic diversity.

Low population which can cause low genetic diversity, poor habitat conditions and habitat loss, road deaths, and commercial development in panther range are constant threats to the Florida Panther's survival.

All these causes are related and therefore affects the Florida Panther.
