Answer:
When Kristen is running and her breathing rate increases, the statement that best describes how her tissues are responding to her running is that they need more oxygen to function, so gas exchange needs to increase.
Explanation:
Options for this question are:
They need more oxygen to function, so gas exchange needs to decrease.
They need more oxygen to function, so gas exchange needs to increase.
They need more carbon dioxide to function, so gas exchange needs to increase.
They need more carbon dioxide to function, so gas exchange needs to decrease.
Physical activity in a person requires an adequate supply of nutrients and oxygen to the tissues, to ensure the production of energy in the form of ATP, obtained from cellular respiration.
A physical exercise implies an increase in the skeletal muscle's ATP demand, so both glucose and oxygen consumption will be higher, which implies an increase in breathing rate to increase lung gas exchange and oxygen bioavailability.

Solution :
In the process to isolate gold that has a 80 percent yield, a 3.00 g of Au is being isolated.
That is, the actual yield of Au is 3. 00 g
Therefore, we need to find the theoretical yield.
As we know,


As actual yield = 3.00 g
percent yield = 80 %
So, theoretical yield = 
= 3.75 g
Thus he should be able to get 3.75 g which is the theoretical yield of Au.

Explanation:
What caused agriculture to change in Britain leading to urbanization? Check all that apply.
You have 45 kJ of heat added and for every 40.6 kJ added, one mole is able to be vaporized. Find how many moles you can vaporize.
45 kJ / 40.6 kJ = 1.1 moles
Water is roughly 18 g per mole so 1.1 moles x 18 g per mol = 19.95 grams vaporized
