1. Which layer of the atmosphere has: a. the most water vapor?
b. the lowest pressure?

2. What remains the same in different layers of the atmosphere?

3. Scientists have divided the earth's atmosphere into different layers. What property of the atmosphere do you think these divisions are based on?

4. You collected data on four layers of the atmosphere. The atmos- phere merges into outer space in an extremely thin upper layer known as the exosphere. Which of the five layers of the atmos- phere do people live in?​

question 1-  a. troposphere b. mesosphere

question 2- Earth's atmosphere is similar to a jacket for our planet. It surrounds our planet, keeps us warm, gives us oxygen to breathe, and it is where our weather happens.

question 3- temperature because Scientists divide Earth's atmosphere into four main layers classified according to changes in temperature.

question 4- Troposphere

Explanation:

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
