Answer & Explanation :-
Research Design is the overall strategical blueprint layout of research; denoting about collection, measurement, analysis of data
- Data variables are independent & dependent variables.
- Dependent variable is the variable being effected by other variables. In this case, it is 'Hyperactivity in children'
- Independent variable(s) are the causal variables which effect the dependent variable. In this case, it is 'New Drug'
- Data is collected through sampling method. Sample of children will be selected from entire population of children.
- Data is analysed on the basis of relationship between variables, through hypothesis testing
- Null Hypothesis [H0] : New drug has no impact on children hyperactivity
- Alternate Hypothesis [H1] : New drug decreases children hyperactivity
Answer:
Expressions we give off
Explanation:
Erving Goffman develop a model called the "Dramaturgical model" which has to do with the presentation of self, meaning, how we presentate to others.
According to Goffman, we create impressions through our language and our body language. So we create impressions by our expressions.
There are two different kinds of expressions:
- Expressions we give: Things we say and intentional poses and facial expressions.
- Expressions we give off: Things over we have less control, it refers to the body language that "gives us away".
In the example, particularly good poker players say they can read other player tells. These are subtle and unintentional facial expressions and body language that reveal what players are thinking. Clearly, <u>players don't do this intentionally and therefore they don't have control over these facial expressions and therefore it gives them away. </u>Thus this is an example of "Expressions we give off"
When a class is through using a culture, it should be deposited on the cleanup cart rather than being poured down the sink drain because doing so runs the danger of contaminating and blocking the sink and necessitating proper disposal of the contamination, which could contaminate the water supply.
<h3>Which of the following actions is necessary if a microbial culture is spilled?</h3>
After telling the instructor that you spilled or dropped a culture, you should wipe the area down with a paper towel and use disinfectant. Clean up the mess with new paper towels after waiting fifteen minutes. After using the restroom, don't forget to wash your hands completely and dispose of the paper towels. Take the proper steps to dispose of any shattered glass.
<h3>Why did you need to use ethanol to clean the work area?</h3>
To maintain an aseptic/sterile environment, 70% ethanol is frequently used to clean surfaces that have been contaminated with microorganisms. Because 70% ethanol will negatively impact bacteria's cell walls and their ability to grow and multiply. Osmotic pressure will be produced when ethanol and water are combined, which is another factor.

With a home equity loan, you can take out a one-time borrowing against the value of your house. While still leveraging the equity in a property, a HELOC enables homeowners to apply for an open line of credit. After that, you are permitted to take out loans as needed up to a specified limit.
What benefits do home equity lines offer?
HELOCs allow you to borrow in smaller quantities so that you only borrow what you need, when you need it, as opposed to home equity loans, which only let you borrow in one big sum. Your monthly payments will be smaller and you'll be less likely to accumulate debt if you just borrow what you actually need.

The answer is shaping. Shaping is normally used to train
animals, such as dogs, to perform difficult tasks; it is also a useful learning
tool for modifying behavior of human. It is a method of training by which
successive estimates toward a target behavior are protected—to test his
theories of behavioral psychology.
