Answer:
<em>The correct option is B) 5-10%</em>
Explanation:
We have seen and depicted various scenarios where we see how different changes arise and dominate the world. Social scientists suggest that as low as 5-10% people of a population are enough to bring about a change because people tend to copy what others are doing. Same goes for countries of the world. Each new popular technique which is learnt by one country tends to become popular and learnt by other countries. For example, the usage of a social app starts with a few members of a population using it and with time it becomes popular in the whole world.
Research is necessary to gather data that is used to formulate a hypothesis and to create the experiment.
Identify a problem. The problem is the question you are trying to answer. Without a problem, there is no reason for experimentation.
Formulate a hypothesis. The hypothesis is a statement, based on your research, that is intended to provide a solution to the problem. The hypothesis is what you are trying to prove or disprove.
Conduct your experiment to prove the hypothesis. A controlled science experiment is setup to test whether a variable has a direct causal relationship on another.
Identify your independent and dependent variables. The independent variable is commonly known as the cause, while the dependent variable is the effect. For example, in the statement A causes B, A is the independent variable and B is the dependent. A controlled scientific experiment can only measure one variable at a time. If more than one variable is manipulated, it is impossible to say for certain which caused the end result and the experiment is invalidated.
Do not alter your hypothesis midway through the experiment. The setup of a controlled scientific experiment must be constant. You can not make changes once you have begun, even if the results you are getting do not seem to support your original hypothesis. When you change your hypothesis, you change the entire experiment and you must begin again.
Do not be upset if your results are not what you expect. Some of the greatest scientific advances have come from experiments that disproved the original hypothesis.
Start over again with a new hypothesis or find new variables to manipulate. Scientific advancement is a painstakingly slow process and scientists often spend years and even an entire lifetime working on the same problem.
A class of lipids derived from cholesterol are called steroids.
Steroids are important large class of biological molecules which are significant components of cell membrane and signaling molecules.
Producers can make their own food by capturing the sun's energy, but consumers don't. Consumers need to eat other organisms to obtain energy.
Answer:
Factor Analysis
Explanation:
Factor Analysis is a statistical procedure that can be used to identify clusters of behaviors (such as verbal skills, intelligence) that are related to a trait.
Factor analysis helps to accumulate a lot of data in many variables into a few variables which can be used for further analysis or study. The aim of factor analysis is to aggregate individual behaviors into a minimized number of factors.
