miss Akunina [59]

Answer:

The allele frequencies of both populations are likely to be similar.

3. Which of the following would best support the theory of evolution?
faltersainse [42]

The theory of evolution will be best supported by the evidence showing a species changes over time. Thus, option A.

Basic evidences for proving the theory of evolution are anatomy, Biological morphology, Fossils and direct observations. There have been various theories for the proof of evolution like structural similarities in an embryo formation pointed towards common ancestors. Theory of Natural selection embarked by Charles Darwin to show genetic variations picked by organisms in whole population.

The most authentic theory over evidence for evolution is Paleontological theory which includes study, observation and acquired prove of fossils of various organisms in the forms of Petrified, mold and cast, trace fossils, compression fossils, impression fossils, etc.

A major disturbance that the ecosystem was able to recover completely from.
kolezko [41]

Hello. Your question is incomplete. However, I managed to find a question exactly like yours on the internet and managed to realize that you forgot to say that your question asks you to give an example of the statement presented above.

Answer:

A major disturbance from which the ecosystem was able to recover completely was the disease that almost wiped out all of Ireland's potato in 1840.

Explanation:

You may have heard of the Irish Potato Famine, which was a time when the Irish population lived very difficult days, after an illness that almost decimated the country's potato plantations.

The potato was the main source of food for the Irish, but in 1840, a fungus called Phytophthora infestans, managed to infect almost all potato plantations in the country, preventing the potato from being harvested and could be consumed. This created major economic and social problems in Ireland, as people suffered from hunger, poverty and the diseases that arose, which caused many Irish people to immigrate to other countries, or to die.

The fungus plagued the ecosystem for years and only started to decrease in intensity in 1850, once the ecosystem started to recover. Currently, although the pest still exists, the Irish ecosystem is completely recovered and the pest is controlled and is unable to make such an impact.

Which optical phenomena are formed by cloud droplets?
kvv77 [185]

Answer:

Cloud iridescence

Sunlight travels through the cloud and is diffracted by the droplets, creating the rainbow effect. It can appear as a patch or band at the cloud's edges and changes as the cloud evolves.
