Explain the relationship between dna, genes, and chromosomes

Answers

Answer 1
Answer: a chromosome is DNA wrapped around proteins knwn as histones. A gene is a part of the DNA that codes for a particular protein
Answer 2
Answer: um i going to just explain random stuff or things however you wanna say it. When a cell needs to be duplicated DNA strands are tightly coiled into chromosomes.Genes are certain stretches of DNA that code for a certain protein with a specific bodily function. On a chromosome, the location of the gene is called a locus. DNA contains all the genetic materiel that decides a person's traits, such as Hair color, Eye color, and more. Tha DnA also passes on traits from the parent to the offspring, which is why children always have common traits with their parents. Genes carry the information needed to pass on these traits. In summary, DNa, genes, and chromosomes are very similar in their composition, since genes are stretches of DNA. Their functions are the same in the sense that they are all vital in passing on traits from the parent to the child, and therefore in determining the physical traits of the offspring.

What are the steps for the scientific method?

Answers

Scientific method is a process that is used to explore various experiments and scientific findings.

Steps for the scientific method:

  • Ask a question.
  • Do research background
  • Construct a hypothesis
  • Test with an experiment
  • Procedure working
  • Analyze data and draw conclusions
  • Communicate results.

Scientific method often ask a question such as, what, how, why, whom, where are some of the questions. Scientist also have to do some background research such as background research plan, finding information.

After background research scientist have to frame the hypothesis and to the hypothesis as well. The next step after hypothesis scientist have to made analyze the data and draw the conclusion.

The steps of the scientific method are to: 

* Ask a Question 
* Do Background Research 
* Construct a Hypothesis 
* Test Your Hypothesis by Doing an Experiment 
* Analyze Your Data and Draw a Conclusion 
* Communicate Your Results 




Ask a Question: The scientific method starts when you ask a question about something that you observe: How, What, When, Who, Which, Why, or Where? 

And, in order for the scientific method to answer the question it must be about something that you can measure, preferably with a number. 



Do Background Research: Rather than starting from scratch in putting together a plan for answering your question, you want to be a savvy scientist using library and Internet research to help you find the best way to do things and insure that you don't repeat mistakes from the past. 


Construct a Hypothesis: A hypothesis is an educated guess about how things work: 
"If _____[I do this] _____, then _____[this]_____ will happen." 

You must state your hypothesis in a way that you can easily measure, and of course, your hypothesis should be constructed in a way to help you answer your original question. 

Test Your Hypothesis by Doing an Experiment: Your experiment tests whether your hypothesis is true or false. It is important for your experiment to be a fair test. You conduct a fair test by making sure that you change only one factor at a time while keeping all other conditions the same. 

You should also repeat your experiments several times to make sure that the first results weren't just an accident. 


Analyze Your Data and Draw a Conclusion: Once your experiment is complete, you collect your measurements and analyze them to see if your hypothesis is true or false. 


Scientists often find that their hypothesis was false, and in such cases they will construct a new hypothesis starting the entire process of the scientific method over again. Even if they find that their hypothesis was true, they may want to test it again in a new way. 


Communicate Your Results: To complete your science fair project you will communicate your results to others in a final report and/or a display board. Professional scientists do almost exactly the same thing by publishing their final report in a scientific journal or by presenting their results on a poster at a scientific meeting. 

How have scientific advancements led to an increase in food safety?

Scientific findings of how to eliminate bacteria with uses of UV light and heat energy were used to protect the life span of food without harsh chemicals.

Answer: all of the above

Explanation:

at which stage of scientific inquiry would scientists find out if their hypothesis were supported by their data

Answers

Interpretation (After experimentation)
The stage of scientific inquiry would scientists find out if their hypothesis were supported by their data is the interpretation of the evidential data they were able to gather. This is where the scientists would be able to find out the outcome of their experimentation and discuss the implication of their result in order to fulfil the study. Hence, in the result and discussion section, here will be the comparison if the hypothesis is to be accepted or denied. In this area, it will also cover the explanations and different theories to compare with the hypothesis outcome.
