Answer:

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.

sasho [114]

Answer:

A. INACTIVE PRECURSOR OF THE ENZYME PEPSIN THAT DIGESTS PROTEINS IN THE STOMACH.

Explanation:

Pepsinogen is the inactive precursor of pepsin produced by the chief cells of the stomach lining. The stomach walls are lined by majorly two types of cells; the chief and the parietal cells. Chief cells secretes pepisinogen and parietal cells secrete hydrochloric acid in the stomach lining. The chief cells upon the signals of increased protein substance in the stomach produces pepsinogen which upon it release, it is activated to the active enzyme Pepsin by the hydrochloric acid from the parietal cell. Hydrochloric acid provides the acidic environment needed for the action of pepsin in the stomach. The pepsin begins the digestion of proteins into small amino acids in the stomach,

pasteur's experiment provided conclusive evidence to reject the spontaneous generation hypothesis, which states that cells arise
Alexandra [31]

The Experiment name is 'swan neck flask'.

Since only one of his two treatments employed the same type of nutritious broth and flask, only one of his two treatments was exposed to preexisting cells.

Nutrient Broth- A common culture medium for undemanding microorganisms is nutrient broth. Numerous standardized techniques for analyzing meals, dairy products, water, and other items advocate it.

Pre-existing Cell- All cells originate from previously existing cells, according to the third component of the cell theory definition. This implies that cells are not created spontaneously, as the term "spontaneous genesis" implies. Current cells are constantly used to create new ones.
