Answer:

The independent factor would be the amount of fertilizer.

Explanation:

An independent variable is the one that changes and has an effect on the dependent variable. Meaning, the independent variable is not dependent on any factor.

In above question, the independent variable is fertilizer because the height of the plant depends on the amount of fertilizer used for it.  The more the fertilizer is used, the higher the plant will grow.

engaged couples who live together prior to marriage are likely to divorce, compared to non-engaged couples who cohabit.
Travka [436]

Engaged couples who live together prior to marriage are less likely to divorce, compared to nonengaged couples who cohabit.

An engagement is the agreement between two people to get married. The couple confirms their intention to wed by announcing their engagement. It is irrelevant whether the couples are of the same sex or not. The ritual of making a proposal is one that has been in use for many centuries. In the past, it was typical for the prospective husband to discuss the terms of the marriage with the father of the bride. Getting engaged is a formal declaration of intent to wed. When the marriage proposal is accepted, both spouses declare their intention to wed. Therefore, an engagement is nothing more or less than a couple's formal proclamation that they want to wed.

Engaged couples who live together prior to marriage are ________ likely to divorce, compared to nonengaged couples who cohabit.

Select one:

a. more

b. much less

c. equally

d. less

What was the importance of Truman doctrine?
saveliy_v [14]

Answer:

President Truman established that the U.S. would be able to provide political, military and economic assistance to all of the democratic nations that are under threat from the external or internal authoritarian forces. In this light, the Truman Doctrine exacerbated the security concerns of the Soviet Union, and therefore stimulated an atmosphere of mistrust, which ultimately paved the way for the breakdown of the Grand Alliance in succmbing to Cold War hostilities.
