An experiment was performed to determine the health effects of different amounts of second-hand smoke on one-year-old hamsters. What is the Independent Variable of the experiment?
Answers
Answer:
Independent variable: different amounts of second-hand smoke
Explanation:
The independent variable in an experiment is the variable that the experimenter changes or manipulates in order to bring about a measurable response.
In this question, a test is being carried out to determine the health effects of different amounts of second-hand smoke on one-year-old hamsters. Based on this, the independent/manipulated variable is the DIFFERENT AMOUNTS OF SECOND-HAND SMOKE because it is the variable being changed.

1. A study was created to test the effects of jazz on people’s sleep patterns. The hypothesis of the experiment was that if people listened to jazz music as they fall asleep, they will sleep for longer periods of time. For the experiment, 2 groups of people were created. One group was placed in a quiet room where they went to sleep and they were timed on how long they slept. The other group was placed in a room where jazz music played softly as they began to sleep and played throughout the night. As each group awoke, their sleep times were monitored.
Dependent Variable: ______________________ Control Group: ____________________________
Independent Variable: _____________________ Experimental Group: _______________________
Answers
Answer:
Independent variable: Jazz
Dependent variable: Amount of time used to sleep
Control group: The group that was placed in a quiet room
Experimental group: The group that was placed in a room where jazz music played softly
Explanation:
In an experiment, the independent variable refers to the variable being changed or manipulated by the experimenter in order to bring about a measurable response. In this experiment, the independent variable is the JAZZ used.
Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the dependent variable is the AMOUNT OF TIME SPENT SLEEPING.
Control groups are the groups in an experiment that do not receive the experimental treatment (jazz music). Hence, the GROUP THAT WAS PLACED IN A QUIET ROOM is the CONTROL GROUP.
Experimental group, on the other hand, is the group that receives the experimental treatment in an experiment. In this case, the experimental group is the GROUP THAT WAS PLACED IN A ROOM WHERE JAZZ MUSIC WAS PLAYED SOFTLY.

Section I: Experimental Overview
Use your answers from questions 1–3 as the basis for the first section of your lab report. This section provides your reader with background information about why you conducted this experiment and how it was completed. Outline the steps of the procedure in full sentences. It also provides potential answers (your hypothesis/es) relative to what you expected the experiment to demonstrate. This section should be 1–3 paragraphs in length.
Section II: Data and Observations
Use your answers from questions 4–5 as the basis for the second section of your lab report. This section provides your reader with the data from the experiment, in a summarized and concise way. No paragraphs are required for this section, but you do need to include the key data and observations from which you will generate your analysis and discussion. This section is objective.
Section III: Analysis and Discussion
Use your answers from questions 6–8 as the basis for the third section of your lab report. This section provides your reader with your interpretation of the data set. You will also give an example of any calculations or formulas you used to analyze your data. Also, you will want to include any graphs that you made and interpret them for the reader.
If you did construct graphs, your Student Guide included information on which graphs to construct. Graphs should have the following:
a. Appropriate titles
b. Appropriate labels for each axis
c. Appropriate scales for each axis
d. Correct units for the data
Complete a rough sketch of each graph. Explain in one or two sentences what trend the reader should observe in each of your graphs.
Mention any problems, unusual or unexpected data, or other factors with the experiment here, and suggest possible causes. This section can be somewhat subjective, unlike Section II, because you are free to include your personal interpretations or even speculation if it adds constructive, reasonable insight to the discussion.
This section is variable in length, and should likely be the longest part of your report.
Section IV: Conclusions
Use your answers from questions 9-11 as the basis for the fourth section of your lab report. In this section you will summarize the outcome of the experiment, and discuss how the original hypothesis(es) was (were) either supported or refuted. Use logic and reason in explaining your statements, and be sure to refer to specific data from your experiment that supports your argument.
This section also demonstrates your understanding of the experiment, through your ability to offer constructive criticism about its design and make suggestions for future experimentation. There are always ways that experiments can be improved. Now that you are a veteran of this experiment and have experience with the procedure, offer some advice to the next scientist about what you suggest and why.
This section should be 1–2 paragraphs long.
Overall
When complete, the lab report should be read as a coherent whole. Make sure that you connect different pieces with relevant transitions. Review for proper grammar, spelling, punctuation, formatting, and other conventions of organization and good writing.

why is fire matter and why is ice matter ?
Answers
Answer:
becouse ice is a solid and fire predouses heat
Explanation:
Answer:
Matter is defined as anything that has mass. Since ice and fire both have mass, they are considered matter. It's easier to see in ice. Ice obviously takes up space and has mass. Fire is a type of plasma. It is oxygen, nitrogen, carbon, and a few other gasses that are extremely hot. They also take up space, have mass, and are hence, matter.

It is important because if not then life would not exist at all except maybe in single cells forms
Explanation:
The body is made of so many cells and without cell specialzation, the cells would not know what to do, they would all be the same. The liver is so different from the skin from the eyes, from the tongue, and so on. That is why we need it so our body can do what it is supposed to do.

The Law of Segregation states that: Question 6 options: Dominant traits will segregate with other dominant traits Genes segregate equally into gametes Recessive traits always segregate together Genes do not influence each other with regard to sorting into gametes
Answers
Answer:
Genes segregate equally into gametes
Explanation:
Gregor Mendel, due to his contribution to genetics, is referred to as the FATHER OF GENETICS. Among his contribution is the principles that governs inheritance in organisms. One of those principles is LAW OF SEGREGATION.
LAW OF SEGREGATION states that the alleles of a particular gene will separate into gametes in an equal manner. For example, in a gene Aa, each gamete produced by the organism with this gene will contain either allele A or allele a in equal proportion.

What are some of the issues that come with catching shrimp in the wild? What are some of the problems associated with fish farms?
Answers
Answer:
Explanation:
There are many issues that can be thought of when it comes to both wild shrimp catching and fish farming. When catching wild shrimp, many fishers like to overfish. This can cause shrimp population levels to drop, and cause them to become endangered. There are also parasites, such as tapeworms in brine shrimp, which turn them bright red and make them very easy prey for bird species and such, and Orthione griffenis, better known as Griffen's isopod, which is a small isopod that attaches to a shrimp's gills and sucks the life out of them. Not only are these revolting, they're causing shrimp species to plummet.
Fish farming is known of, and is a very profitable business. However, there are many concerns that can arise. One of these concerns is unethical treatment of the fish. Some farmers may starve or overfeed their fish, meanwhile others may overbreed them. There's also concerns of how the fish are acquired. If fish are taken from the wild to be farmed, some may see this as cruel or inhumane. Quality of life for the fish is a large concern, as if a fish is unhappy or ill, it can cause the consumer to fall ill from the product, which wound cause trouble for many.
There are many more issues that could arise, but overall, these are some of the most major issues when it comes to shrimp catching and fish farming.
