Scientific investigations that involve some kind of testing will make use of observations. generally speaking making observations is the first step of the scientific method.
According to the equation the correct answer with the interval registered in minutes is: C
8=0.00146 (distance to epicentre) <=> distance to epicentre=8÷0.00146 <=>5479,45 km
Answer: Chemical weathering changes the composition of a rock, while physical weathering does not.
Explanation: The definition of a chemical change is a change that cannot be reversed and is caused by a chemical reaction. In this case, a chemical change to a rock would change the composition of the rock while physical changes may change the appearance of the rock, but not the composition.
Explanation:
Option first is the correct one
RNA synthesis depends on RNA polymerases (RNAPs). This is the enzyme
that faciliates copying a sequence of DNA which is the first step
leading to gene expression. This multi-step process is important for
researchers to understand especially in relations to studying how
genetics influence disease processes.
