Over [174]

Answer:

Musca domestica

Explanation:

The number of unique gametes produced by a diploid individual is 2^n, where n is the number of pairs of chromosomes (or the haploid number).

For that reason, species with higher number of homologous chromosome pairs will show greater genetic variation in the progeny.

  • Drosophila melanogaster has four pairs of chromosomes, so it can produce 2^4=16 different gametes.
  • Musca domestica has six pairs of chromosomes, so it can produce 2^6=64 different gametes.

Musca domestica has more genetic variation.

Sever21 [200]

The right option is; d. Runoff describes water movement and infiltration describes water storage.

Runoff is the portion of precipitation, irrigation or snow melt that flows over land as surface water instead of infiltrating or evaporating. Factors that influence runoff are permeability, amount of rainfall, slope and vegetation.  

Infiltration is the process by which water or precipitation on the ground surface moves into the soil. Factors that determine the rate of infiltration include; soil type, topography of the land, amount of precipitation, vegetation, and pre-saturation levels.
