Mutations are errors in the genetic code and/or in the protein synthesis process (which is the process of reading the genetic code to make proteins). In which two structures/organelles are mutations most likely to occur?
a) Ribosomes and endoplasmic reticulum
b) Nucleus and endoplasmic reticulum
c) Ribosomes and lysosomes
d) Nucleus and ribosomes

i believe you meant to say air rather than hair so the answer is below ")

the dead sea, the lowest place on earth at 430 metres (1,410 ft) below sea level, has a correspondingly high typical atmospheric pressure of 1065 hpa.

d. groundwater flows through the subsoil and deposits minerals.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
