please help In this technological age students are faced with online educational opportunities at both the high school and post-high school level. Many educators wonder how effective such online courses really are. Imagine you are an educator designing an online course. Before beginning, you decide to conduct a study about their effectiveness. In this study, which would most likely be considered the dependent variable? A) student scores in on-line courses B) student scores in off-line courses C) number of students taking on-line course D) number of high school students taking on-line courses
Answer:
B
Explanation:
The dependent variable would probably be student performance in online courses. So, the correct option is A.
What is Dependent variable?The variable being measured and anticipated to change as a consequence of the modification of the variable that is independent is known as the dependent variable. Although the independent variable in this study is not explicitly stated, it can be assumed to be the online course. The variable being tested to ascertain the efficacy of the online course would be the dependent variable.
Student performance in online courses would be the dependent variable, out of the available possibilities, that is most pertinent to measuring the efficacy of the online course. The study can assess whether online courses are equally effective as offline courses in regards to student learning outcomes by evaluating and comparing student scores in online programmes with those in offline courses.
Therefore, the correct option is A.

Answer:
Scientific knowledge can be changed.
Explanation:
For example, the Cell Theory. The Cell Theory has been changed over and over again, leading to what it is know. People didn't have microscopes when the cell theory was first discovered, so when microscopes came along, we found out more about cells and revised the cell theory.
Genetic variation—the presence of a variety of possible alleles for a trait in a given population—is an indicator of a species’ ability to survive changes in its environment. Explain how this genetic variation in the peppered moths influenced the species’ chance of survival.
Answer:
yes.
Explanation:
The black mutation allowed the species to survive the increasing pollution in its environment. The pollution caused the trees to be covered with soot. Black moths were more likely to survive in that environment. Without this mutation, peppered moths would have likely decreased in number when the environment changed.

In the 1980s laws were passed to reduce the amount of certain chemicals used by companies and individuals. According to these laws, the use of chlorofluorocarbons, or CFCs, should be reduced and eventually eliminated. These compounds contain chlorine and cause problems when released into the Earth’s atmosphere.
These laws are meant to reduce which human-induced environmental change?
nonnative species introduction
non-sustainable harvesting
ozone layer depletion
eutrophication
Answer:
Eutrophication
Explanation:
These laws are meant to reduce which human-induced environmental change eutrophication.
What is Eutrophication?Due to the increased availability of one or more limiting growth elements required for photosynthesis, such as sunlight, carbon dioxide, and nitrogen fertilizers, eutrophication is characterized by excessive plant and algae development .
As lakes deteriorate and accumulate sediment over generations, eutrophication naturally takes place (Carpenter 1981).
However, human activities have dramatically adversely affected drinking water sources, fisheries, and recreational water bodies by speeding up the rate and extent of eutrophication.
Therefore, These laws are meant to reduce which human-induced environmental change eutrophication.
