Sometimes scientists have different explanations for the same observations. For example, before scientists understood atoms, they had different explanations for matter. What did these differing explanations lead scientists to do?

A) Scientists made more observations about the makeup of matter.

B) Scientists made fewer observations about the makeup of matter.

C) Scientists voted on a common explanation on which they could agree.

D) Scientists stopped studying matter until microscopes were introduced.

A) Scientists made more observations about the makeup of matter.

Explanation:

Different scientific explanations leads scientists into making making more observations about the make up of matter.

When there are different school of thoughts about a known phenomenon, it spurs more curious observation which will eventually lead to formulation of testable hypothesis along the line.

Through this phase, the scientists studying this problem will have pools of evidence to support or discard a proposition.

It is common place to have differing explanations. They often times lead to better scientific discoveries.

step-by-step explanation:

we are given

we have to simplify it

firstly, we will factor it

now, we can cancel like terms

now, we can combine it

so, we get

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
