Answer: It may be unethical to some people due to their beliefs. But as science evolves,genetic engineering has made it possible for us to modify many things,including human DNA. To me,changing human DNA is ethical. Changes in DNA bring many positive consequences,for example lower the risk of many deadly diseases(cancer/cystic fibrosis,etc). We can modify our features and create "a perfect human". But,there are some dangers that come with this power. For example,DNA modification could go wrong and create dangerous species

Synthesis of an inducible enzyme requires Select one:
Leona [35]

Answer: B

Explanation:

Synthesis of an inducible enzyme requires the substrate bound to repressor.

In the synthesis of a specific inducible enzymes, a substrate on which the enzyme acts must bind to the repressor that prevents the synthesis of the inducible enzyme. Example of an inducible enzyme is β-galactosidase in Escherichia coli that degrades lactose and galactose.

The synthesis of β-galactosidase is regulated by a repressor protein, that binds to the region of deoxyribonucleic acid (DNA) that codes for the synthesis of β-galactosidase. If lactose or galactose (substrate) is present, it acts as an inducer which induce the repressor protein from binding to DNA. Hence the enzyme is synthesized

How have renewable resources helped the human population in the last 100 years? We have increased technology in many ways. Choos
timama [110]
Renewable resources helped the human population in the last 100 years, by giving us a cleaner environment, and allowing us to harness the usage of energy generated from wind, solar, etc, to change it into electricity, which could help things move or give it power. For example, electricity can be used to charge the laptop or phone you are using, it can be used to power cars (Tesla), etc.
Something that is detrimental in the last 100 years, is the technology of missiles and nuclear power. Sure, nuclear power can help create power and the like, however, it can also be used to create weapons of mass destruction. It also pollutes our environment, which can lead to health problems.  Finally nuclear energy is usually associated with Nuclear bombs, which would affect the environment, destroy human population and how they live, and damage the land for hundreds of years. Example of this includes Hiroshima and Nagasaki, which are still affected today from the 1945 atomic bombs. Some solutions to this is to get the affected things to outer space, and send them far away from earth. However, this is costly, and it could have a backlash if not done right. Another way is burying under the ground, however, this should not be used extensively, due to poisoning in the ground, and it would affect the people, animals, and plants.

using these two paragraphs, you can build up the rest of the essay. For the 4th paragraph, compare the two. For the first paragraph, introduce the problem. For the Last paragraph, give a summary, and give your opinion.


hope this helps
