Did Darwin first believe that each finch he found was a different species?

No, Darwin did not believe that they were different species.

The differences in the finches proved his theory of evolution to be likely. The finches evolved based on traits that fit their environment. The different finches were the same species, however, their traits differed based on their environment.

Populations evolve for many reasons. Suppose there is a population of plants that have either purple flowers or white flowers, a
sattari [20]

Answer: natural selection

Explanation:Natural selection, gene flow, gene drift and mutation are the mechanisms for EVOLUTION.

The dominant purple allele must have been acquired from previous parent gene, by natural selection

Definitely the available   alleles from previous flower population were white and purple flowers. But, because the parents of purple flowers exhibit VARIATION, in their gene pool,  they showed dominance over  the recessive white colour flowers in the same population.  

◼ from Darwin’s observation and deduction, Organisms who acquired certain characteristics from variation  tend to survive than others, and therefore pass these inheritable characteristics to their offspring.

◼Thus the purple flowers dominated the population for the available resources, among the other flowers colours, (competitions) therefore it leads to a stable population in size after a period of time., while the white colour flowers are recessive

◼Darwin concluded that, variants of best adaptation will be selected for by natural conditions operating in the environment of the population at that particular period (natural selection).

Based on this, natural selection takes place, and the purple flowers with best variation will have selective advantage (dominance)above white colour flowers(recessive).

Consequently, they have higher survival rates compare to white flowers in the population this is   survival of the fittest by natural selection of purple flowers

The frequency of the white colour flower will reduced because of less manifestation of traits from generation to generation from reduced gene pool due to recessive trait, however the frequency of Purple flower will increase because the number of copies of allele of purple flowers is greater than the total number of all the flowers population( white flowers+purple)

How does the location of the carbon in the sugar molecule differ between the strands
scoundrel [369]
During a dehydration reaction, two monomer molecules are covalently bonded to each other, with the loss of a water molecule. In this reaction, each monomer contributes part of the water molecule that is released during the reaction. This reaction is repeated as monomers are added to the chain one by one, making a polymer.

Cellulose-digesting microorganisms live in the guts of termites and ruminant mammals. The microorganisms have a home and food, a
Yuki888 [10]

Answer:

The correct answer is: mutualism

Explanation:

Mutualism refers to a relationship between two organisms, where both organisms benefit from the association. In this instance, the relationship between cellulose-digesting microorganisms and their hosts-  termites and ruminant mammals- is characterized by mutualism because both organism benefit from their association. The microorganisms benefit by getting their nutrition from the cellulose in guts of their hosts. Whereas, the hosts benefit from the cellulose-digesting microorganisms by getting help in digesting the cellulose they consume in their diet.
