Helga [31]
The correct answer is to accurately measure core temperature.
The tube seen entering the reporter's nose is a thermistor which is used to measure the core temperature of the body with very high levels of accuracy. The tube reaches the esophagus, which is one of the most preferred locations for measuring the core temperature.
The core body temperature is the operating temperature of the human body and it refers to the temperature of the deeper structures of the body instead of the peripheral tissues. 
The esophagus is close to the left ventricle of the heart, it has a deep body location and a quick response to any changes in the body temperature.

<h3>What does phenotypic classification entail?</h3>

phenotype, all of an organism's observable traits that emerge from the interaction of its genotype (total genetic inheritance) and environment. Observable features include things like behavior, biological characteristics, colour, shape, and size.

Decomposers are important because they​
eimsori [14]

Answer:

Decomposers and scavengers break down dead plants and animals. They also break down the waste of other organisms. Decomposers are very important for any ecosystem because if they weren't in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up.
