Please answer the following question:

As temperature decreases, which takes precedence? Energy dispersal or positional randomness

What are the different biological functions of nitric oxide (NO)?  How does NO affect how the drug nitroglycerin works in the body?  How does nitric oxide work in muscle relaxation?

I tried to answer it, but I'm not sure if it is right, please help!

I need help with this question and I know have two parts, but it counts as one question. Please respond as soon as possible.

The 24 power plants in Baltimore metro area collectively emit about 40,300 metric tons of CO2 per day (www.carma.org), thereby increasing the level of greenhouse gases in this region. To counter this, environmentalists plan to plant trees in the area. How many moles of CO2 are emitted by these power plants every day? (1 ton =1000kg, molecular weight of CO2 is 44g) If on average 500 moles of glucose are synthesized by a tree each day, how many moles of CO2 can a single tree convert to glucose in a single day? How many trees need to be planted to reabsorb all the CO2 released into the atmosphere every day by these power plants? If a single tree occupies an average of 8.00 x 10-5 sq miles, what percent of the area of Baltimore city needs to be forested to counter the CO2 emitted from power plants alone?  (total area of Baltimore city is 92.00 sq miles)

THIS CAN NOT BE HAND DRAWN!

Which diagram is the correct one?  What other procedure can be used to solve this problem? write down ways to solve.  first, execute plan 1 to solve the problem. Please explain every step.  Think about the way that you can use to make sure that your answer makes sense. write down your assessment.

Can you please help answer the organic chemistry question attached?

Consider the molecule below. HICA H3C Br CBCH3 CH3 How would you characterize the personality of the molecule above? [Select] Would the reactive part of this molecule react with equal probability on the top or bottom face? [Select] Could this molecule undergo a rearragement, and if so, what would it become? [Select] Which carbon atom has a greater partial positive both Ca and Cb have equal am◇ charge? Which atom would make a bond with a nucleophile? Br

Biofuels such as wood generate carbon dioxide when they are burned, but biofuels are nonetheless considered a partial solution to climate change. Why? Because plants take carbon dioxide out of the air as they grow, and burning them puts the same amount of carbon dioxide back into the atmosphere, so they are "carbon neutral". Because biofuels are more expensive than fossil fuels, so people will use less of them and generate less carbon dioxide. Because wood and other biofuels contain only a small amount of carbon, so they do not generate very much carbon dioxide when burned. Because wood and other biofuels generate a lot of ash when they burn, and this ash in the atmosphere cools down the Earth.

Animal fats and vegetable oils become rancid when exposed to air because

In general, the larger the molecule, the higher the boiling point in the data table. explain why some of these molecules have higher boiling points even though they may not have a larger mass? Include at least two pieces of evidence from the data table along with support from chemistry concepts learned in module 4. It may help to draw out some of the structures.
