Answer:
A) Reaction X used a catalyst
Explanation:
Reaction X has a lower activation energy and the most likely cause of this would be a catalyst.
The question is not given. You just placed some statements. Apparently, here you have some definitions to pair with the type of elements. So, I will separate the statements as per my best understanding. If the question requires anything else tell me to give you more details.
<span>1. Metalloid
Metalloid is an element that has properties in between metals and non metals, this is metalloids have some properties of both.
Then you can pair it with ---> moderate ability to conduct heat and electricity
2. noble gas
The elements that are knwon by not reacting with other elements are noble gases.
Then, pair this with ---> will not react with other elements.
3. metal:
Metals are malleable, polishes to a luster and are good conductors of heat and electricity.
Then pair metal with ---> malleable, polishes to a luster;
conducts heat and electricity well
4) non metal gaseous: non metal are poor conductors
So, pair this with ---> does not conduct heat or electricity well
Given that the question is no

DNA structure. DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C).
