Answer:
A. slavery was no longer profitable
Explanation:
During the industrial revolution, American businesses started to used modern machines to replace the existing manual labor. This made using slaves no longer as profitable as it used to.
As a result, people started to give support to abolish slavery. But this support tend to be coming from the northern states. At that time , the southern states were not as willing to adopt the technology from the industrial revolution. This made the southern states still reliant on slaves. This what caused the conflict that lead to the civil war.
Answer:
The answer is theory.
Explanation:
A theory is described as a confirmed explanation for natural phenomena, which has basis on scientific knowledge. This implies that a theory can be proved or disproved using tests.
The term is slightly different from a <u>hypothesis</u>; a hypothesis is a possible explanation that has <u>yet</u> to be confirmed through scientific tests.
The placenta, umbilical cord, and other membranes are detached and expelled during the <u>third </u>stage of birth.

The main reason for using a factorial design instead of separate experiments (with one iv per experiment) is to find an interaction between the independent variables.
Factorial designs allows the effect of a factor to be estimated at several levels of the other factors, giving conclusions that are valid over a range of experimental conditions. It is necessary when interactions are present to avoid misleading conclusions and it is more efficient than the 1-factor.
Interactions are measured as the mean of the differences between simple effects. So, in such experiments we study the individual effects of each factors and their interactions. And in factorial experiments a wide range of factors are used.
