Answer:
Certain fossils, called index fossils, help geologists match rock layers. To be useful as an index fossil, a fossil must be widely distributed and represent a type of organism that existed for a brief time period. Index fossils are useful because they tell the relative ages of the rock layers in which they occur.
TRUE. Most drugs are eliminated by the kidneys in urine although some are excreted in saliva, sweat, or exhalation.

This system is responsible for all the sensations we feel – cold, hot, smooth, rough, pressure, tickle, itch, pain, vibrations, and more. Within the somatosensory system, there are four main types of receptors: mechanoreceptors, thermoreceptors, pain receptors, and proprioceptors.
Explanation:
Aminoacyl-tRNA synthetases recognize their specific amino acid by charge, size and R group and recognize the tRNAs that carry it by the nucleotide sequence .
Aminoacyl-tRNA synthetases are enzymes that attaches the appropriate amino acids on to its tRNA . These are also responsible for performing the first step of protein synthesis.
Breaker waves are waves that reach a specific amplitude that causes certain energy transformations. They are formed due to the rise of the ocean floor.
<h3>What are breaker waves and their formation?</h3>
A breaker is a type of wave that is formed due to the rise of the ocean floor or the bed in the oceanic zones. They reach the shores towards the shallow water because of the water breaking or collapsing.
The breaker waves have increased heights when the water depth and wavelength decreases. It is called a breaker because it breaks something.
Therefore, option A. the rise of the ocean floor cause the formation of the breaker wave.
