<span>Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). DNA safely and stably stores genetic material in the nuclei of cells as a reference, or template. Meanwhile, mRNA is comparable to a copy from a reference book because it carries the same information as DNA but is not used for long-term storage and can freely exit the nucleus. Although the mRNA contains the same information, it is not an identical copy of the DNA segment, because its sequence is complementary to the DNA template.</span>
The answer is Event 1. A solar eclipse occurs when the moon gets between the sun and Earth and blocks the sunlight from reaching Earth's surface during daytime, thus casting a shadow over Earth. A lunar eclipse as represented by Event 2 happens when the moon passes into the shadow of Earth at night and we can see the moon darken.
Given what we know, we can say that biology and neo-Darwinism both support the idea that natural selection explains how the environment selects organizations for survival or extinction.
<h3>Natural Selection. </h3>
- This concept is often summarized by the phrase "survival of the fittest".
- This refers to the ability of an organism to adapt to its environment.
- The better-adapted organisms will live to pass on their genetic information, thus changing the organization of the species.
- Those not able to do so will face extinction.
Therefore, since natural selection involves the survival or extinction of a species based solely upon their ability to adapt and change their genetic organization in response to their environment, we can say that this concept helps to explain how the environment selects organizations for survival or extinction.
