Feeling the tremors of an earthquake a scared resident of seventh floor of a multistoryed building starts climbing down the stairs rapidly. Which hormone initiated this action?

(a) adrenaline

(b) glucagon

(c) gastrin

(d) thyroxine

Expert Solution

The correct option is Option A - Adrenaline

Adrenaline, also known as Epinephrine, is a hormone released by the adrenal glands in response to any emergency ofr threat faced by the body. It is also known as the 'flight-or-fight' hormone. When adrenaline is released, it mediates the immediate conversion of glygogen into glucose, which are used to produce ATP molecules. The body therefore receives an instant surge of energy, which is crucial for any vigourous or sudden action ( such as climbing down the stairs rapidly in stressful situations).

Besides, adrenaline also increases the the heart rate, increasing blood pressure, expanding the air passages of the lungs, and increasing the overall metabolic rate of the body.

The other 3 hormones are involved in metabolic process.

Glucagon is produced by the alpha cells of the pancreas.It raises the blood glucose levels in the body, but not as quickly as adrenaline.

Gastrin is a hormone released by the parietal cells in the stomach. It aids in the breakdown of food and it digestion.

Thyroxine is the major hormone of the thyroid gland.It is a mediator of various metbolic processess.

1) a. There is an elevator on the 102th floor of the Empire State Building with a sign: MAXIMUM WEIGHT 2900 LBS. During refurbishment, the cable was being replaced. A section of the new cable is cut up and tested for its breaking strength. The cable was tested 20 times and the average breaking point of the sample was found to be 3100 LBS with a standard deviation of 280 LBS. Construct an appropriate hypothesis test that determines whether the...

The terrace roof of a building at sea level is planned to have a rectangular floor area with dimensions of 10 m and 20 m. The prevailing wind speed in winter is u∞=25 km/h, and air temperature is assumed to be T∞=0°C. Considering that the outer surface temperature of the building is To=10°C, how should the building be positioned with respect to the prevailing wind direction to minimize the heat loss from the roof?
