When should I make a decision on my own and when should I get advice from someone?​
tia_tia [17]

Answer:

Making decisions can be difficult. So, it all comes down to what you feel.

Explanation:

What I mean is, lets say you really wanted to buy this one special car. You could technically afford it, but you may have to take out some loans. Thats an example of a decision you can basically make on your own. Now a decision when you should get advice from someone is kinda a more complex situation.  For example, lets say you were struggling with something and you didnt know what to do with yourself to get you out of this difficulty. Then thats pretty self-explanitory, you would ask for advice in that kind of a situation. Now I dont know what kind of a decision your making or if this is a question for homework, but this is honestly just my opinion soooo yeah. By the way if this didnt make any sence im deeply sorry.

All your muscles need more oxygen during exercise?
SashulF [63]

Answer:

Yes

Explanation:

When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. To cope with this extra demand, your breathing has to increase from about 15 times a minute (12 litres of air) when you are resting, up to about 40–60 times a minute (100 litres of air) during exercise.
