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.

Contact [7]

Answer:

The correct answer is B. Myopia is also known as nearsightedness.

Explanation:

Myopia is a refractive defect of the eye in which parallel light rays converge at a focal point located in front of the retina, instead of converging on the same retina; it is the inverse defect to farsightedness, in which the light rays reach the retina before converging.

A person with myopia has difficulty focusing well on distant objects, which causes visual acuity deficits and can also lead to headaches, strabismus, visual discomfort and eye irritation.

Connect photosynthesis and respiration be sure to include in your discussion the function of mitochondria and chloroplasts
Vadim26 [7]

Photosynthesis makes a sugar for the plant, in order for photosynthesis to occur the plant needs carbon dioxide and water, and with the use of the sunlight it produces oxygen and glucose. For respiration you need glucose and oxygen which produces carbon dioxide, water and ATP(energy) for the cell. I hope this helps, I only know the first half of the question.

hichkok12 [17]

Answer:

First off, grab a simple magnet and hold it near your precious metal coin. If the coin is even slightly attracted to the magnet, then you know you have a fake on your hand, as metals with contents of iron and steel are the most likely to be attracted
