Meat is not a good source of protein because it does not provide the body with all the essential amino acids.a. True
b. False

Answers

Answer 1
Answer:

Answer: False.

Meat is a good source of protein. There are nine essential amino acids which are required under special conditions like illness.

These are-  Histidine, Leucine, Isoleucine, Valine, Threonine, Methionine, Lysine, Phenylalanine and Tryptophan. They cannot be synthesized by the body and therefore need to be taken from external protein sources.

Since meat contains all the essential amino acids, therefore it is considered as a good source of protein. Hence, the given statement is false.

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.

An earthworm tunnel floods during a rainstorm, and the earthworm washes out onto the grass. According to Ch.27, what is the importance of the moisture from the tunnel to the earthworm?

Answers

Answer and explanation;

  • The moisture pertains to its survival due to its respiratory surface. Such that too much water and the earthworm could die and  too little water and the earthworm could dry up and die. Keeping their skin moist allows them to respire.
  • Earthworms are important as they plow the soil by tunneling through it, which provides the soil with passageways through which air and water can circulate.
  • The activity of the earthworms depends directly on soil moisture and temperature. They become active when soil thaws in the spring and move deeper in late summer as the soil dries.
The moisture from the tunnel to the earthworm is how they survive, too much moisture will kill them. And there abundant food source is located there.
