In the year 2500, five male space colonists and five female space colonists (all unrelated to each other) settle on an uninhabit

ed Earthlike planet in the Andromeda galaxy. The colonists and their offspring randomly mate for generations. All 10 of the original colonists had free earlobes, and 2 were heterozygous for that trait. The allele for free earlobes is dominant to the allele for attached earlobes.
If four of the original colonists died before they produced offspring, the ratios of genotypes could be quite different in the subsequent generations. This is an example of?

Answer:

The correct answer is genetic drift.

Explanation:

The phenomenon of changing the frequency of an allele in a specific population with time is known as genetic drift. The mentioned gene variation or the modification in the frequency of the allele is required to take place abruptly so that the phenomenon of genetic drift can take place. The environmental factors do not play an essential role in the phenomenon of genetic drift to take place.  

The process of genetic drift occurs generally due to random sampling of organisms, it illustrates the random change in the number of gene variants within a population. When the existence of the different forms of a gene, that is, alleles, enhances or reduces by chance with time within a population, the phenomenon of genetic drift occurs. Thus, the mentioned case is an illustration of genetic drift.

How does the movement of particles of matter change when temperature increases?
saveliy_v [14]

Answer:

Increases

Explanation:

The movement of particles of the matter increases with the increase in temperature.

The particles gain kinetic energy with increasing temperature and move in faster rate.

<u>For example:</u> When we blow a balloon with our mouth, we increases the temperature inside the balloon, the particles in the balloon gain kinetic energy that leads to the faster movement of gas particles in the balloon and they collide with each other and surface of balloon, after a peak the balloon get burst because of high kinetic energy and high collision.

Hence, the correct answer is "increases".

Precipitation _____. drives the water cycle is the change from a solid to a gas happens more frequently than evaporation over la
ipn [44]

Answer: Precipitation occur more frequently than evaporation over land.

Explanation:

Precipitation refers to the water vapour that fall from the atmosphere in form of rain, snow, sleet, freezing rain or hail. It delivers water from the atmosphere to the Earth. Precipitation occur more on the land than evaporation, most water that teaches the surface of the Earth fall back on the land and fill the inland water, rivers , storages,e.t.c.

Evaporation occur frequently in the ocean because it is expose to the sun and most water that is evaporated from the ocean fall back to the ocean as precipitation.
