A nswer: -

C. Energy is released by the reaction

Explanation:-

An exothermic reaction is one in which during the progress of the reaction heat is evolved.

So energy is released by the reaction.

It cannot be created as energy is neither created nor destroyed as per the Law of conservation of energy. Energy is not transferred either.

The energy released during the progress of the reaction originates from the chemical bonds of the reactants as they break during their conversion into products.

Arden is making a pros and cons list about genetic engineering for a debate at school. Which part of her list is incorrect?
Soloha48 [4]

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.
