Old thermometers contained very small amounts of mercury. The mercury in the photo has a melting point of -38°C. What can u conclude about the melting point of the mercury in the old thermometer?

The thermometer can not be used to measure very low temperature

Explanation:

Mercury-in-glass thermometer is one of the types of liquid-in-glass thermometers.

Given the very melting point of mercury, it is unsuitable to attempt to use this thermometer for very low temperature measurement.

Hence, from the melting point of mercury, this thermometer can not be used to measure very low temperature.

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
