<span>"Genetic drift is more likely to have an impact on small populations."

Genetic drift is changing the frequency in the allelic pool of a population. This phenomenon impacts mainly smaller populations because these populations have only a few copies of the alleles present. If a change in the frequency of the alleles happens then it may cause the disappearance of certain alleles because there are only so many copies.</span>

List and briefly describe each of the 4 types of evidence that support evolution
tiny-mole [99]

Answer

  • Anatomy Species may share similar physical features because the feature was present in a common ancestor <u><em>(homologous structures)</em></u>.
  • Molecular biology DNA and the genetic code reflect the shared ancestry of life.
  • Biogeography The global distribution of organisms and the unique features of island species reflect evolution and geological change.
  • Fossils Fossils document the existence of now-extinct past species that are related to present-day species.
  • <u><em>Direct observation</em></u> We can directly observe small-scale evolution in organisms with short lifecycles <u><em>(e.g., pesticide-resistant insects)</em></u>.

Which factor is a major cause of the changes that
slamgirl [31]

The changes that occur during puberty are mostly a result of changes in hormone levels in the body.

<h3>Puberty</h3>

The transition from a child to an adult is caused by changes in the level of some hormones in the body.

In females, there is an increase in follicle-stimulating hormones as well as luteinizing hormones, leading to an increase in the production of progesterone.

In males, there is an increase in the production of testosterone hormone among many other hormones.

Both progesterone and testosterone are responsible for the development of physical features in females and males respectively.

Historical path leading to the widespread adoption of sugar cultivation in americas:
kati45 [8]
The first historical record associates the beginning of sugar in the Americas with Christopher Columbus' initial and epic voyage of the discovery of the New World in 1492.

The sugar cane plant is native to Southeast Asia and in Europe had already created an appetite for more through the Eastern trade routes. These were of course difficult routes that included trade caravans over land and water to reach Asia from Europe.

With Columbus the initial planting of sugar cane occurred in the Dominican Republic. The Caribbean islands maintain a perfect tropical climate for the plant and as such, flourished. Other colonizers, like the British, Portuguese and French soon followed suit within their own colonies spread throughout the New World. 

The Portuguese had transplanted or moved some of the seedlings, or small plants from the Dominican into Brazil and other areas of their colonized lands. In fact, Brazil is the largest producer of sugar cane in the world today.

The desire for more sugar during this early settlement, led to a "triangle of trade". In order to satisfy the need for production of sugar, ships sailed to the western coasts of Africa to bring slaves to work the sugar plantations. After depositing the slaves, the ships would pick up sugar and rum, an alcohol created from sugar, and bring these goods back to the European powers. This completed the cycle for the ships, which would then return to Africa to gather more slaves.

By 1505, this trade route was set up and going strong. And for the next 300 years or so, would remain in effect.
