Answer:
c. switching from beef to soy
Explanation:
Switching from beef to soy shall lead to the curbing of lifestyle diseases such as obesity.
At the same time, soy shall provide the nutrients that were needed by the body and could be obtained from beef.
Beef is much expensive compared to beef, thereby, there shall be experienced low expenditure compared to beef.
Therefore the switching from soy to beef shall be a more sustainable food system.
Answer:
2) CAG - TTC - ACG mutates to CAG - TTC - ACC - ACG
Explanation:
Insertions are mutations in which extra base pairs are inserted into a new place in the DNA. The number of base pairs inserted can range from one to thousands!
In option no. 1: We see that there is not addition of a single or more than one base, but the new base sequence is different from the original sequence at three places i.e: TTA - CAC - G
In option no. 2: The insertion of three bases ACC has been made exactly after TTC, the whole sequence and arrangement of bases remain same except this insertion.
In option no. 3: The first base of the sequence T is replaced with A, and all other sequence is same. This type of mutation is called substitution in which one base is replaced by other.
In option no. 4: The last base of the sequence C is deleted, and is not present in new sequence. This type of mutation is called deletion in which a base is removed from the sequence.
Conclusion: Therefore, the best option is 2, in which whole codon is inserted in the DNA base sequence.
Earth's surface wind generally blow from regions of higher AIR PRESSURE TOWARDS REGION OF LOWER AIR PRESSURE.
The direction in which the wind blow on the earth surface is a product of many factors, the most important of these factors are: pressure, friction and Coriolis effects. On the earth surface, the wind normally blow from high to low pressure. A high pressure system followed by a low pressure system allows the wind to flow in clockwise direction outward toward a low pressure system. This ensures the continuous flow of the wind.
DNA<span> is transcribed into RNA, 1 base of </span>DNA<span> corresponds to 1 base of RNA, this 1 to 1 relation is not used in the translation to </span>protein<span>. During this translation, 1 amino acid is added to the </span>protein strand for every 3 bases in the RNA so b<span>efore double stranded </span>DNA<span> is turned into </span>protein<span> it first goes through a process called transcription. </span>
