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.
Explanation:
Answer: Na, S, Cl
Explanation:
Atomic size decreases as one moves from left to right on the periodic table with elements in the same period. This is as a result of the electrons increasing in the outer circle and thus being drawn to the protons in the nucleus which will lead to the outer shell area decreasing.
Sodium (Na) comes before Sulfur (S) which comes before Chlorine (S) so this is the decreasing order as they are all in the same period.
It is a mutation of the gene that makes hemoglobin, hemoglobin is a protein that carries oxygen in red blood cells.
