How secondary sources should be used in an analytical research report, compared to primary sources.
Natasha_Volkova [10]

Answer:

Secondary sources help us have a big picture of a topic and understand how other researchers have approached it. They often interpret and analyze many primary sources that can be difficult and time-consuming to synthesize by ourselves. They allow us to:  

• Gain an overview of the topic  

• Support or contrast our arguments with other researchers’ ideas  

• Gather information from primary sources that are not directly accessible

Therefore, it can be helpful to consult secondary sources when you write a report. If you want to mention an article or study cited in a secondary source, search for the original source and cite it directly.

If you hold your breath, what gas builds up in your blood
Otrada [13]
<span>If you hold your breath, <span>carbon dioxide </span></span><span>builds up in your blood

The reason for this is:

When you exhale or breathe out, you exert or let out carbon dioxide. So, if you were to hold your breath, it would build up because it is not being exerted.


Hope this helped you!
