Answer:

hi dude will hlp u with 2nd question hve no idea with the table

2) A hot air balloon is a lighter-than-air aircraft consisting of a bag, called an envelope, which contains heated air. Suspended beneath is a gondola or wicker basket (in some long-distance or high-altitude balloons, a capsule), which carries passengers and a source of heat.The heated air inside the envelope makes it buoyant since it has a lower density than the colder air outside the envelope.

a) Hot air balloons can travel up to 40,000 feet, however humans would start to die at 10,000 feet. This level of the atmosphere is called the Troposphere.

b)The heated air inside the envelope makes it buoyant since it has a lower density than the colder air outside the envelope. As with all aircraft, hot air balloons cannot fly beyond the atmosphere. The envelope does not have to be sealed at the bottom, since the air inside the envelope there is at about the same pressure as the surrounding air.

tia_tia [17]

Answer:

sensor

Explanation:

Homeostasis refers to the ability of an organism to maintain the internal conditions of the body irrespective of the external conditions.

The homeostasis is maintained by the homeostatic mechanism which involves the 3 components which are the receptor or sensor, the integrating centre and the effector or organ.

In the given question, the peripheral chemoreceptors measures and sense the pH of the blood therefore the peripheral chemoreceptor will be considered as the "sensor component" of the homeostatic mechanism.

Thus, the sensor is the correct answer.
