Water molecules are polar (positive charge zones and negative charge zones) this makes the attraction of a na+ ion or a cl- ion to occur.

<h3>How are the water molecules composed?</h3>

This class of molecules that have a distribution of charges are called polar and, consequently, form bonds called hydrogen bonds with other molecules.

These molecules have a permanent dipole moment, that is, they have a structure called dipolar (two poles), this arrangement gives water great power to dissolve substances within it.

Therefore, we can conclude that water molecules are polar (positive charge zones and negative charge zones) this makes the attraction of a na+ ion or a cl- ion to occur.

Degger [83]

Science is not testable is not a characteristic of science.

The omitted options include :

science is a process.
science is a body of knowledge.
science must follow the scientific method.
science is not testable.

<h3>What is a Scientific method? </h3>

A scientific method refers to the step by step process that scientists must follow in order to give scientific explanation of a phenomena or invention of an idea that is testable.

The scientific method includes:

Observation
Constructing a hypothesis/ testable explanation
Conducting experiments to test the hpothesis
Formulation of theories based on experiments
Conducting further experiments and research
Making conclusions/Formulation of laws.
Reporting, and evaluating.

Thus, the characteristics of science include:

science is a process.
science is a body of knowledge.
science must follow the scientific method.

Therefore it is wrong to say that science is not testable.

Which of the following most directly explains the importance of improved agricultural productivity to the industrialization of e

dsp73

The importance of improving agricultural productivity for the industrialization of economic production in Europe in the period from 1750 to 1900 is that as less labor was needed on farms, more people moved to urban areas to work in factories.

<h3 /><h3>First Industrial Revolution</h3>

It began in England in 1760, a period in which the transition from the feudal to the capitalist system took place. This transition occurred due to the technological development in Europe, which generated several economic and social transformations in the world.

Therefore, the impacts of the Industrial Revolution are related to the productive processes, which ceased to be artisanal to be developed in factories with the use of machines, thus emerging new working relationships.

The correct answer is:

Because less labor was needed on farms, more people moved to urban areas to work in factories.
