Sound wave is gathered by Pinna ; which is outer ear !!
So C is your answer !!
Answer:
The devise used to convert thermal energy to mechanical energy are called heat enignes
The letter only has reflection symmetry, if you rotated it it would look the same.
DNA and RNA are amplified in vitro using polymerase chain reaction (PCR), which is frequently employed in biochemical analysis.
The PCR process is very temperature sensitive, and thermal management is crucial to PCR operation in order to maintain the necessary set points for temperature at each stage of the procedure. The objective of this investigation is to develop a thermal approach that can quickly boost the heating/cooling thermal cycle speed while keeping the substrate that contains the aqueous nucleic acid sample at a constant temperature. This study examines a novel microfluidic PCR heat cycler that makes use of a suitably configured design that is filled with a porous material.

<h3><u>Answer;</u></h3>
The statement above is <u>False</u>;
<h3><u>Explanation;</u></h3>
- Saturated hydrocarbons also known as alkanes contain only a single covalent bonds between carbon atoms. The common feature found in all saturated hydrocarbons is carbon-carbon multiple bonds.
- Unsaturated hydrocarbons are hydrocarbons in which all the valencies of carbon atoms are not fully utilized by single covalent bonds. They contain at least one double or triple bond in their structure.
- <em><u>Characteristic reactions of alkanes or saturated hydrocarbons are substitution reactions. Unsaturated hydrocarbons characteristics reactions are addition reactions.</u></em>
