Scientists use fossils to learn about organisms' lives and evolutionary relationships, to understand geological change, and even to locate fossil fuel reserves.
It is most likely due to the fact that the attenuation is the evolutionary relic, which by accident has remained does not support the actual reason of the dual control to regulate the operon.
Answer: Option E
<u>Explanation:</u>
In bacteria transcription and translation carries out at the same time so or the termination of transcription in premature phase in bacteria uses a special mechanism which is called as attenuation T.
he attenuation in bacteria is a regulatory mechanism. Trp operon is the group of codes of the components. These operons are the actual functioning group of the DNA.

Answer:
ions?
Explanation:
If it picks up or loses an electron, it becomes electrically charged and highly reactive. Such electrically charged atoms are known as ions. ... In an effort to achieve equilibrium, the atom emits particles in the form of radiation until the nucleus is stable. Such unstable atoms are said to be radioactive.
1. <span>The North Star, or Polaris, is the brightest star in the constellation Ursa Minor, the little bear (also known as the Little Dipper). As viewed by observers in the Northern Hemisphere, Polaris occupies a special place. The point in the night sky where the projection of the earth's axis lies is known as the North Celestial Pole (NCP). As the earth rotates on its axis (once every 24 hours), the stars in the northern sky appear to revolve around the NCP. Polaris lies roughly one half degree from the NCP, so this particular star appears to remain stationary hour after hour and night after night. 2.</span>
