Because of the connection between greenhouse gases and climate change, there has been a concerted to reduce greenhouse gas emissions. the decrease in co2 emissions in 2015 from fossil fuel combustion was a result of multiple factors, including all but: a) a slight decrease in the use of public transportation throughout the country. eliminate b) substitution from coal to natural gas consumption in the electric power sector. c) a slight decrease in electricity demand due to conservation efforts in all sectors. d) warmer winter conditions resulting in a decreased demand for heating fuel in the residential and commercial sectors.

A)a slight decrease in the use of public transportation throughout the country.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.
