Global warming is caused by the holes in our ozone layer, which the holes were caused by all the pollution in the atmosphere,
Answer:
The correct answer is B.It was necessary that each of the two phage components, DNA and protein, be identifiable upon recovery at the end of the experiment
Explanation:
Hershey and chase in his experiment lebelled the T₂ bacteriophage with radioactive sulfur and radioactive phosphorus separately. Then they infect E.coli with T₂phage and separated phage from bacteria by centrifugation.
Because DNA contains phosphorus not protein, cells infected with phage containing radioactive phosphorous showed radioactivity bacause DNA enters the cell not protein confirming DNA is the genetic material and radioactive sulfur was found in supernatant.
The numerical value of the sun's apparent magnitude and absolute value brightness is -23.
Magnitude is a unit used to describe how brilliant an object is to our eyes.
Both the phrases apparent and visual magnitude refer to the brightness of an object that we can see.
The Sun's apparent magnitude is -23.
The brightness of an object increases with decreasing number, and vice versa.
Without the use of visual aids, the human eye can see things up to a distance of 6.5.

Answer:
The greenhouse effect:
The process in which gases in the atmosphere trap heat from the sun and warm the Earth. is the natural warming of the Earth’s atmosphere Solar radiation enters the atmosphere mainly as light and some of that radiation is absorbed by the Earth’s surface then changed to heat that is reradiated into the atmosphere where it is absorbed by greenhouse gases then reradiated back to Earth again
