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.

In which of the following ways are DNA and mRNA similar?
Naddik [55]

Answer: alternative D.

What might hershy and chase have concluded if they had found 35s instead of 35p in bacterial cells? Explain your answer
kaheart [24]

Hershey and chase have concluded that DNA is not protein it was the genetic material.

Explanation:

Hershey and chase said that DNA is not protein it was the genetic material. They took a direct physical approach in finding the genetic material. They both determined that a protective coat was formed around the bacteriophage.

The internal DNA is not a protein, a genetic material. They used label to find it. The lack of 32p labeled DNA remaining in solution after bacteriohages are allowed to absorb the bacteria showed tha DNA was transferred into the bacterial cell.

The radioactive 35s in the solution shows that protein coat protects the DNA before adsorption.
