Answer:

<h2>A site for the exit of the diphosphates removed from the nucleotide triphosphates.</h2>

Explanation:

Transcription occurs in three steps, i) initiation, ii) elongation, and iii) termination.

Elongation: during elongation , the RNA polymerase add new nucleotides in the growing chain of RNA molecule until it encounter terminator factor, or until it terminate transcription.  RNA polymerase has three prominent channels, i) channel for entry of DNA template strand, ii) channel for exit of DNA strand  and iii) channel for exit of newly synthesized RNA molecule. There are lots of other enzymes which helps in transcription.

Why is it impossible to predict the phenotype of the offspring by observing only the phenotype of the two parents?
igomit [66]

Because some trait's phenotypes don't indicate their genotypes so in order to predict the phenotype of the offspring you have to know the genotypes of the parents

Answer:

The theory of evolution first formulated in Darwin's book is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits that allow them to better adapt to its environment, survive and have more offspring.

Ernst Mayr divided Darwin's theory into 5 unique parts.

Ernst Mayr divided Darwin's theory into 5 unique parts.Evolution as such

Along with Buffon and Lamarck, Darwin supported the ability of species to change over time.

Common Descent

Darwin felt that all of the diversity of life on earth emerged out of the evolution from one or a few common ancestors.

Gradualism

While Lamarck felt that species-wide change could take place within the span of a few generations, Darwin felt evolution was a much slower process, taking place in innumerable small steps.

Population Speciation

This portion of Darwin's theory states that within a population, change in a species occurs as the balance of hereditary characteristics shifts across that population. This differs from Lamarck's idea that each individual in the population must undergo the same change. According to Lamarck, all giraffes living under tall trees would develop long necks. According to Darwin, some would randomly be born with long necks, this hereditary trait would gradually spread throughout the population.

Natural selection

Natural selection is often called the most unique part of Darwin's theory. Competition had been thought of as a reason that a given species might succeed or go extinct, but Darwin extended the understanding to change within a species. To continue the example of giraffes: when a giraffe is born with a longer neck than its fellows, it gains an advantage because it is able to reach more food. The long-neck giraffe is therefore stronger, lives longer, and more likely to have offspring. These offspring are born with the same long neck as their parent, though some might have even longer necks.

Returning to the example in the figure, in the first generation the application of the pesticide causes the death of most of the non-resistant insects: only those resistant to the pesticide survive. These insects reproduce and maintain their resistence so that the second generation will be more resistant than the first. So we have Natural selection, speciation, gradualism and evolution in act all together.
