The structural feature in a molecule necessary for a gas to absorb IR radiation is: a net change in dipole moment due to the vibration or rotation of the molecule.
IR radiation is the infrared radiation. In the electromagnetic spectrum, its value ranges from 700 nanometers to 1 millimeter. The waves are longer than that of visible light and shorter than the radio waves. The waves are not visible to the human eye.
Dipole moment is a vector quantity. It is equal to the charge of the molecules multiplied by the distance between the two charges. In a dipole there is a positive charge at one end and a negative at the other. The direction is considered from negative to positive.

A metamorphic rock is a type of rock which has been changed by extreme heat and pressure. so must be option D
Bacteria and fungi carry out decompostion of plants and animals
<span>Amylase needs an optimum pH for its activity. It is in the range of 6-7. Below or above pH will denature this enzyme. The pH level is optimum for this enzyme in the mouth and hence it catalyses the break down of sugar. The pH level of stomach is lower than its optimum level duet to the activity of gastric acid. Hence the enzyme becomes inactive in the stomach.</span>
Answer:
During transcription, only one strand of DNA is usually copied. This is called the template strand, and the RNA molecules produced are single-stranded messenger RNAs (mRNAs). The DNA strand that would correspond to the mRNA is called the coding or sense strand
Explanation:
