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:
Aluminium oxide has higher melting point than aluminium chloride because there nay be some impurities in the oxide which affects the intermolecular force of attraction
A lunar eclipse can be photographed sometimes when Earth is in between the sun and the Moon.
<h3>Why lunar eclipse occur?</h3>
A lunar eclipse occurs when the Sun, Earth, and Moon align in the same line in which the Moon passes into Earth's shadow. In a total lunar eclipse, the entire Moon falls within the darkest part of Earth's shadow, called the umbra so we can conclude that claim 2 is the right answer about lunar eclipse.

His observation and census.
Answer:
D. 2.5 x 10 ^-14 Hz
Explanation:
Use wavelength formula: v = f x wavelength
Rearrange formula for frequency.
f = wavelength / v
f = 7.6 x 10 ^-6 / 3.00 x 10 ^8
f = 2.5 x 10^-14 Hz
