Thanks please help me
aye yall trash af
Of course! I can help you with the questions. Let's go through them one by one:
4. A controlled experiment is designed to test a _____
To answer this question, it would be helpful to understand what a controlled experiment is. In a controlled experiment, the researcher manipulates one variable (independent variable) while keeping all other factors constant. The purpose is to determine the effect of the independent variable on the dependent variable. So, the blank in this question is asking for what a controlled experiment is designed to test. Think about what the purpose of conducting a controlled experiment is.
5. What is it called when a scientist's personal opinion affects the way experimental results are reported?
This question is asking for a term that describes when a scientist's personal opinion influences how they communicate or present their experimental results. Think about how a scientist's bias or personal beliefs can affect the reporting of their findings.
6. Which of the following questions can be answered scientifically?
To determine which of the given questions can be answered scientifically, you need to understand what makes a question scientific. Scientific questions are based on observations and can be tested or investigated using the scientific method. Consider the given options and evaluate if they meet the criteria of scientific questions.
7. Which of the following is not a benefit of scientific literacy?
In this question, you're asked to identify the option that does not represent a benefit of scientific literacy. To answer this, you need to understand the concept of scientific literacy and think about the advantages it brings. Then, choose the option that does not fit.
8. Which of the following is a way to stay safe in the science lab?
To find the answer to this question, you should have knowledge about laboratory safety practices. Identify the safety measures typically followed in a science lab setting.
9. Identify the air in the following statement: "A scientific theory is a well-substantiated, fact-based, and unchangeable."
This question is asking you to identify the error (air) in the given statement about scientific theory. Read the statement carefully and think about whether it accurately describes the nature of scientific theories.
10. What is both a way of studying the natural world and a body of knowledge?
Consider the options provided and think about a term that encompasses both studying the natural world and a collection of knowledge about it. You can think about the nature and scope of scientific inquiry.
11. Facts, figures, and other evidence gathered through observation are called ____
To answer this question, you need to identify the term that describes the information collected through observations. Consider the nature of observation in the scientific process.
12. What is a logical conclusion based on observed evidence?
For this question, you should think about the process of drawing conclusions based on evidence. What term describes a conclusion that is based on logical reasoning from the data or observation?
13. Which of the following describes what scientists expect to happen every time under certain conditions?
Here, you're looking for a term that describes the outcome that scientists believe will occur consistently under specific conditions. Consider the concept of predictability in scientific studies.
14. What is the particular use of scientific knowledge to solve everyday problems and improve lives?
This question is asking for a term that describes the practical application of scientific knowledge to address real-world issues and enhance human life. Think about the ways that science can be used to solve problems and make advancements.
15. What can be used to make complicated concepts and systems easier to study and understand?
Consider the options given and think about a tool or method that helps simplify complex concepts or systems, making them more accessible for study and comprehension. Think about common techniques used to aid understanding in scientific disciplines.
By critically thinking about the concepts and using your knowledge about science, you should be able to figure out the answers to these questions. If you need help with specific questions, feel free to ask for further clarification.
4 is hypothesis or theory
5 is bias
Now let me give you some advice. You will not learn any of this by getting others to do your work for you. Read you notes/your printed material/ web sites/etc. There is no easy way to do any of this. One of these days you will be on your own and will have a job. How long can you continue to get another person to do your work for you? The time to get an education is when you're young and not when you're 50 years old. I know most if not all of this advice will fall in deaf ears but you need to be warned that this way of getting answers is not in your best interest. Education is the key to becoming a self supporting person with the ability to fulfill dreams and have a happy life with a loving family. Don't put off until tomorrow what you can do today. Take care and good luck.
