Answer:
<em><u>Naturalistic Observation</u></em> and <em><u>Survey</u></em>
Explanation:
A study on consumer behavior is intended to provide data on the real behavior of customers.
Naturalistic observation <em>is a strategy of studies that psychologists and other social scientists frequently use.</em> This approach focuses on the observation of an individual or subject in their natural environment.
A survey is described as a technique of study <em>used to gather data from a predetermined group of participants in order to obtain information and perspectives on different subjects of concern.</em>
Answer:
The reason is that, despite the distance, most objects / stars in the night sky, are not really that small, but appear very large.
Explanation:
While magnification in telescope helps to enlarge the object of focus, it is however, not always a good thing when doing astronomical viewing, due to the following reasons:
1. With higher magnification, a bigger object may not fit into the view, as a result of the total field view becoming smaller. For example, it will be easier to see the whole Andromeda galaxy on a small or low power view than on higher magnification.
2. Since most objects or stars in the sky are not so bright, applying higher magnification will make them look dimmer than necessary, thus will be difficult to observe. For example, during observation of Orion Nebula, it will be difficult to observe the body, if the telescope is magnified than necessary.
3. The presence of atmosphere or atmospheric conditions on earth also affects the telescope or magnification, as a clear and steady atmosphere helps the imaging of telescope to be sharp, while the unclear and turbulent atmosphere makes the imaging to be less detailed.
Answer:
The correct answer is A. control the movement of substances in and out of the cell.
Explanation:
All cell membranes are made up of lipids and proteins. Lipids are organized in two closely adjoining sheets that form a lipid bilayer. This bilayer provides the basic structure of the membrane and acts as a permeability barrier (impermeable) for most water-soluble molecules. Cells live and grow by exchanging molecules with the surrounding environment and the plasma membrane acts as a barrier that controls the transit of molecules into and out of the cell. As the interior of the membrane (the lipid bilayer) is hydrophobic, the membrane tends to block the passage of almost all water-soluble molecules (which dissolve in water). Protein molecules, which are normally “dissolved” in the lipid bilayer, act as mediators or facilitators of almost all membrane functions, either by transporting specific molecules through it or by catalyzing membrane-associated reactions, such as synthesis of ATP.
During the 1930s, the combination of the Great Depression and the memory of tragic losses in World War I contributed to pushing American public opinion and policy toward isolationism.
