<span>Answer: a. take place in nuclear reactors
</span><span>Controlled nuclear chain reactions are the reaction in nuclear reactors. The reaction is controlled to make its rate slower. This will make the reaction relatively safer, so the energy produced can be changed into electricity in power plant. When the reaction is not controlled, it could cause explosive like in nuclear bomb.</span>
During active transport, the sodium pumps would transfer the solutions opposite the concentration gradient. This means that it would go from Solution A to Solution B
Answer:

Explanation:
To be specific to the question, the answer would be no as analogous structures do not show that two distinct come from a common ancestor. However, it shows the evolutionary relationship by stating that the species have different evolutionary origins and developmental patterns as they developed the organs with similar function and appearance but anatomically and embryological development is different.
