Answer:
We can predict or comment about reactivity of elements by taking into consideration their electronic configuration that imparts stability or un-stability to an atom.
Explanation:
Reactivity : It refers to the affinity of a substance to combine with other substance .
Elements are mainly of two types :
In terms of metals or non metals it can be defined as tendency to loose or gain electrons .
- On the basis of it ,we can easily make out or comment about the reactivity of element (metal or non metal ) .Like ,if an element has completely filled outermost shell or we can say have stable electronic configuration then it is already stable .Therefore , it won't react with any other element .
- But, if its outer shell isn't complete then in order to attain stability it will combine or react with other .Hence , we can say it will be quite reactive .
Answer:
Topoisomerase and Primase
Explanation:
Topoisomerase — Relaxes the super-coiled DNA
Primase — Provides the starting point for DNA polymerase to begin synthesis of the new strand
<span>The behavior that is not a result of seasonal changes is : C. circadian rhythm
Cicadian rhythm refer to the Physiological cycle that's experienced by living organisms within a day, This cycle is not a reasolg of seasonal change because the factor that influence it the most is time period within 24hours, and the time process usually the same no matter what season they are in</span>
