Why do scientists try to control most variables in an experiment or observational study
In an experiment or observational study, scientists control most variables to isolate the impact of the independent variable on the dependent variable without the influence of other factors. This allows for assessing cause-and-effect relationships accurately and minimizes bias. Control and experimental groups are used for comparisons.
Explanation:Scientists strive to control most variables in an experiment or observational study to ensure the reliability and objectivity of their results. The key idea is to isolate the impact of the independent variable on the dependent variable without the influence of other extraneous factors.
An example provided is the use of a control group and an experimental group in a drug efficacy study. Both groups would be nearly identical in all ways except for one - the experimental group receives the actual drug while the control group receives a placebo. This design allows scientists to attribute any observed differences in the groups' outcomes to the drug, rather than some other uncontrolled factor.
In such experimental research, one characteristic (the explanatory variable) is manipulated to observe its effect on another characteristic (the response variable). This careful control and manipulation of variables provide a way to test cause-and-effect relationships and make causal statements. It's crucial to note that to minimize bias, researchers often conduct experiments in a controlled environment and maintain the same conditions for all groups, except the variable being studied.

The Collective Unconscious Earlier in this lesson, you learned about the idea of a collective unconscious set forth by psychoanalytic "dissident," Carl Jung. This concept is not only important to the field of psychology, but it is one that is widely used by various disciplines in the Humanities. For this assignment you will create a brief PowerPoint presentation that illustrates the collective unconscious of your particular culture. What sort of symbols and archetypes emerge from your research? What sort of values and/or meanings do these symbols represent? How does this collective unconscious influence individual behavior
The collective unconscious is the part of the unconscious mind that carries ancestral memories and experiences. Symbols and archetypes derived from it are reflective of a culture's values and beliefs. These symbols, shaping beliefs and actions, can influence individual behavior.
Explanation:The collective unconscious, a concept introduced by Swiss psychiatrist Carl Jung, is a part of the unconscious mind that is derived from ancestral memory and experience and is common to all humankind. This collective unconscious manifests in the form of archetypes and symbols. These symbols, which emerge out of a particular culture, are resultant of values, beliefs, and experiences shared across generations in that culture.
As an example, in American culture, the bald eagle could symbolize freedom and independence due to its significance in national imagery and its portrayal as a free and powerful creature. Similarly, liberty and equality might be personified as Lady Liberty. Such symbols often have an impact on individual behavior by shaping their beliefs, motivations, and actions through collective societal influence.
So, when doing the research for your PowerPoint presentation, you need to look for such symbols and archetypes in your culture which may include folklore, religious or historical figures and events, national symbols, etc. Once you identify these symbols, try to understand the underlying values they portray and how they might be influencing individual and collective behavior in your culture.

How did Canada solve economic problems in the early 1900s?
A.) Canada began to industrialize
B.) Canada increased mining for gold
C) Canada borrowed money from the US
D.) Canada began to slow down immigration
**Will give Brainliest to which ever answer really catches my eye :)
A.)
Canadian historians until the 1980s tended to focus on economic history, including labour history. In part this is because Canada has had far fewer political or military conflicts than other societies. This was especially true in the first half of the twentieth century when economic history was overwhelmingly dominant. Many of the most prominent English Canadian historians from this period were economic historians, such as Harold Innis, Donald Creighton and Arthur R. M. Lower samboo project. Scholars of Canadian history were heirs to the traditions that developed in Europe and the United States, but frameworks that worked well elsewhere often failed in Canada. The heavily Marxist influenced economic history that dominates Europe has little relevance to most of Canadian history.[citation needed] A focus on class, urban areas, and industry fails to address Canada's rural and resource based economy. Similarly, the monetarist school that is dominant in the United States also has been difficult to transfer north of the border.
The study of economic history in Canada became highly focused on economic geography, and for many years the dominant school of thought has been the staples thesis. This school of thought bases the study of the Canadian economy on the study of natural resources. This approach has since also become used outside of Canada, such as Australia and many developing nations.
Before the arrival of Europeans, the First Nations of what would become Canada had a large and vibrant trade network. Furs, tools, decorative items, and other goods were often transported thousands of kilometres, mostly by canoe throughout the many rivers and lakes of the region.
The early European history of the Canadian economy is usually studied through the staples thesis which argues the Canadian economy developed through the exploitation of a series of staples that would be exported to Europe. Studies show that Canada's economy is growing very well.
Why do you think some Egyptians objected to the idea of being ruled by a women?
PLEASE ANSWER FOR A BRAINLEST ANSWER! <3
Final answer:
Some Egyptians may have objected to female rulership due to societal norms and traditions that favored male succession, despite women's significant legal rights and societal roles.
Explanation:
The objection to being ruled by a woman in ancient Egypt may have stemmed from the socio-political norms of the time, despite the relatively progressive status women enjoyed. Although Egyptian women had legal rights and played significant roles in society, there was still a prevailing preference for male leadership, influenced by longstanding traditions and the symbolic importance of a male pharaoh. The case of Hatshepsut, for instance, exemplifies this tension; she ruled competently as pharaoh for two decades, but after her death, steps were taken to erase her legacy, which could suggest a discomfort with female rulership from her successors, whether due to expectations of male succession, an assertion of their own legitimacy, or the perception of female rule as an aberration.
