Answer:
The part of Arden's list that seems to be wrong is that genetic engineering can create organisms that survive in different environments (Pro 2).
Explanation:
Genetic engineering is a branch of genetics that introduces the use of technology to modify a living organism by introducing modified DNA into its original genome in order to improve its characteristics
The organisms subjected to changes by genetic engineering are called genetically modified organisms or GMOs, and can be stronger, longer-lived, more productive, or resistant to disease.
<em>Making a species resistant to any environment could cause it to develop in places where it could not live before, affecting the natural balance of an ecosystem to which it previously did not belong, so Pro 2 on Arden's list does not seem to be entirely beneficia</em>l.

I just did that quiz on k12 8th grade
1 proton and-1 electrons and 0 neutron
Answer:
28.1
Explanation:
Divide the percentage abundances by 100:
92.2% ÷ 100 = 0.922
4.7% ÷ 100 = 0.047
3.1% ÷ 100 = 0.031
multiply them by their corresponding mass number:
0.922×28 = 25.816
0.047×29 = 1.363
0.031×30 = 0.93
add them all together to get your final answer:
25.816 + 1.363 + 0.93 = 28.109
to one decimal place:
28.1
I hope that helps!!!
