Answer: Option 2) .the information on the strand changes
Explanation:
The rearrangement of nucleiotides in a DNA strand could be reversing the position of a chromosomal segment (Chromosomal inversions) OR interchanging the genetic parts of chromosomes (Chromosomal translocation)
In either case mutations occur because the information on the strand changes.
These amino acids are ariginine,histidine, isoleucine,valine, leucine, methionine,threonine,lysine,phenylalanine, and tryptophan
False. For the northerners winter occurs when Earth is closest to the sun.
Due to the theory of continental drift, continents and landmasses can move apart and together on plates. This particular case has the fossils dating back to approx. 300 mya, when there was the supercontinent Pangea. During this time, all modern continents were squished together, allowing for all of the continents mentioned in the question above to be connected, in turn allowing for the Glossopteris plant to grow and fossilize on all of the continents.
The Hubble Telescope is used for the observation of stars and galaxies that are far away from the universe and also for viewing the planets in our solar system.
<u>Explanation:</u>
It was 1990 when, the Hubble Space Telescope was launched. It mainly aims in the observation of the universe and the place from where the elements that make up the space has emerged. After the discovery in 1990, the observations made by this is about 1.3 million.
It is considered to one of the most important and a useful instrument that has been discovered. It only revolves around the earth and takes the images of stars,planets and other galaxies without reaching them. The mechanism of optics and detectors that more sensitive in nature are attached to this instrument.
