Answer:
This very simplified overview of the fields that flow together to form the basis of bioengineering helps us identify some of the fundamental ethical issues in bioengineering. These are issues that concern, again, the domain and focus of bioengineering, the views of nature that govern the activities of bioengineering, the impacts of bioengineering, its limits, risks and safety factors, the question of activism, and that of intellectual responsibility. Starting with the domain, a first issue is whether the ethical responsibility of bioengineering should be exclusively human-centric or could be extended to a broader bio-centric domain. The issue of animal experimentation, for instance, evolves around this question. Should bioengineers be concerned exclusively with the health of humans, or should they have a broader responsibility over all life forms?
Explanation:
I would go with B. Because they are the most used.
The radical in this question is OH.
The reason this will be a radical, is that the definition of a radical is the presence of an unpaired electron. This causes the radical to be unstable, desperately wanting to do something with the free electron that it has.
Oxygen has a charge of 2-, and Hydrogen has a charge of +1. When you pair them, you end up with a net charge of 1-, which is the presence of that unpaired electron. It will usually be written as: 
Answer:
The correct answer is "horizontal gene transfer".
Explanation:
The most common way at which genes are transferred is vertically, from parents to their descendants. However genes could be transferred among species, in what is known as horizontal gene transfer (HGT). HGT is most clearly seen in bacteria, actually HGT is the cause of the phenomenon of the development of antibiotic resistance. The theory of an ancient mitochondria moving their genes to the chromosomes of its host is most likely the result of HGT. This makes sense since an ancient mitochondria most likely behaved as an alpha proteobacteria, an ancient bacteria that already developed its HGT mechanism..
<span>because they are the ones able to harness free energy such as the sun and store it in sugars and other biological chemicals such as fats and proteins. other creature like us eat them to gain our energy so without them we would all starve</span>
