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.
The correct answer is option D, difficulty of redesigning workable ecosystems
Reason -
The area that was redesigned into an ecosystem actually failed to attract the endangered species of clapper rails in California because of the following two reasons –
a) Failed attempt of restoration of Cord grass ( a tree which is a dominant tree in the nesting habitat of clapper rail) . Even if few such trees were there they could not grow to their full height and thus were incapable of providing adequate nesting cover
b) Due to the lack of predatory insect, some herbivore insect in the ecosystem attacked the green grasses thereby making the nesting inadequate.
Genes are typically hundreds or thousands of base pairs in length because they code for proteins made of hundreds or thousands of amino acids. Most genes contain the information needed to make functional molecules called proteins.
