False because <span>Like DNA, RNA is assembled as a chain of </span>nucleotides<span>, but unlike DNA it is more often found in nature as a single-strand folded onto itself, rather than a paired double-strand. Cellular organisms use </span>messenger RNA<span> (</span>mRNA<span>) to convey genetic information.</span>
Question 1: All of the above
Question 2: Has mass and takes up space
Question 3: True
Question 4: A<span> definite volume but no definite shape.
Question 5: Liquid
Question 6: A</span><span> substance with a high conductivity that easily transfers heat

Answer:
Option (D)
Explanation:
In terms of chemistry, a catalyst is usually defined as the substance that is commonly used in a reaction in order to increase the rate of reaction, without getting consumed. It helps in the reduction of activation energy.
In the given case, the lever or a person can be considered as a catalyst because both of these will increase the efficiency (or rate) in removing the rock from the top of the perch. Thus, the lever or the human will remain the same after the removal of rock as a catalyst can be recovered after the reaction.
Therefore, the correct answer is option (D).
<span>It will have little impact in the long run. Muscular dystrophy tends to interfere with the formation of muscular tissue, specifically it causes problems with the manufacturing of proteins necessary to maintain muscular tissue. This procedure would mean a temporary improvement in the subjects condition, but does not seem to provide a true permanent solution. Repetitive stem cell therapy may be able to slow down the conditions progression though.</span>
