Fill in the missing words. naturalselection foundereffect geographicallyisolated species evolution
grandymaker [24]

Hi!


The ancestral finch founded a new population on one of the Hawaiian Islands. Due to the founder effect , allele frequencies of the first small population on one of the islands could have differed from their continental goldfinch-like ancestors. The process of natural selection resulted in adaptation and evolution of the island population into a new species over time. Some of the birds crossed to some of the other islands where they were geographically isolated and evolved into more species occupying different niches.


In terms of population genetics, founder effect is when there is a loss of genetic diversity as a result of the establishment of a new population by a relatively few individuals. Following such an establishment, natural selection is the process  which results in the genes of the fittest individuals of the population being selected over generations. This process ultimately results in evolution, and over time may give rise to new species. Geographical isolation is the physical separation of a population from another owing to geographical changes in the terrain or area. If two populations of the same species are geographically isolated, there is a great chance over time they may evolve into two different species.


Hope this helps!

Why are fossilized organisms so different from the animals on Earth today?
Sonbull [250]

Answer:

Fossils provide evidence about life on Earth that currently extinct. Through fossils, we've discovered several species of animals and plants that previously existed. We also learn how life on Earth changed throughout the years. Fossils found in younger rocks look like animals and plants that are living today. Fossils in older rocks look less like the current living animals and plants. Some fossils found look either more or less like current species we know today.

Scientists are testing substance L to determine how it enters mammalian cells in a culture. The cells maintain a 120 millimolar
Dmitrij [34]

Answer:

The substance L moves inside the cell through active transport.

Explanation:

Active transport can be described as the movement of substances from an area of lower concentration to an area of higher concentration against the concentration gradient.

In the above question, The substance L enters the membrane despite the cell having a higher concentration of substance L. Hence, the mode of transportation is active transport as the substance L is moving from an area of lower concentration to higher concentration. This process usually consumes energy rather than releasing energy.
