Biology

irinina [24]3 years ago
5 0

<u>Answer:</u>

Continuous pumping of water causes drawdown. The water table lowers rapidly.

<u>Explanation:</u>

  • Water table is the level below which the ground is saturated with water.
  • During rainfall the runoff water percolates into the ground through the gap in the soil particles and the water table is recharged.
  • But when gallons of water are pumped continuously it leads to a drastic reduction in the water table because, water from the surrounding aquifers move towards the place where the vacuum is created by pumping.
  • To prevent this, the groundwater should be recharged and over drawing should be avoided.

Identify which type of natural selection is described in each case below.
ICE Princess25 [194]

Answer:

Results in the evolution of the species: Directional selection

Results in new species: Disruptive selection

Favors traits at the two extremes: Disruptive selection

No increase in diversity: Directional selection

One extreme trait is favored: Directional selection

Diversity decreases: Stabilizing selection

Diversity increases: Disruptive selection

Explanation:

Directional selection which is also known as positive selection is known to be a mode of natural selection. In this type of selection, an extreme phenotype is favored over other phenotypes. This makes the allele frequency to move in the direction of that phenotype and this takes place over time.

Disruptive selection (known to be diversifying selection) talks about the certain changes in the population genetics whereby extreme values of a particular trait are favored over intermediate values. This results in new species.

While Stabilizing selection is a natural selection whereby there is a stabilization of the population mean on the particular value of a non-extreme trait. Here the diversity is decreases.
