Calcium absorption increases when the body's calcium status is low?

true.


What does LDPE stand for?

Low density polyethylene (LDPE), a thermoplastic made from oil. The product is: * Light-weight * Good impact resistance * Extremely flexible * Easily cleaned * Thermoforming performance * Meets food handling guidelines * No moisture absorption * Chemical-and corrosion-resistant


Is it true that a low density gas must be hot in order to produce an absorption line?

False


What is sensible heat without moisture?

Sensible heat is the heat required to raise the temperature of a substance. When determining the heat of a vapor, moisture must be considered as it removes heat from the vapor (in order to heat the moisture [water vapor] to the ambient temperature). Dry steam has no moisture. Dry air has no moisture (a physical improbability). Air normally has moisture determined as relative humidity. This humidity [water vapor] must be heated with the air. Then the moisture heat absorption must be subtracted from the whole to determine the heat absorption of the air without moisture, expressed as heat per unit per degree (often 0.24 btu per dry standard cubic foot per degree F for air). Any moisture in the air increases the heat necessary to raise the temperature by about 1 btu per pound of moisture per degree F. (0.004 btu per gram of moisture per degree F). This increased heat requirement becomes more evident as air is compressed, and the moisture is removed by condensation.


What does it mean if one found negative absorption in uv-vis absorption graph?

That means your blank has a higher absorption at that particular wavelength than the sample. This really shouldn't happen assuming your blank is water.
