Which of the following most significantly determines a communities’ access to potable water? a. access to clean raw water sources b. the availability of money c. local drought conditions d. the level of industrial development

b. the availability of money.

Portable water is the water which can be useful for human drinking and food preparation. Portable water should be free from physical and chemical contaminants such as heavy metals, plant and animal contents, other organic wastes, microbial contaminants such as bacteria, viruses and parasites. With the availability of money communities can make water suitable for use and can make their own portable water. Some of the water treatments like chlorination (which ensures removal of microbes and physical contaminants), filteration (removal of physical and chemical contaminants) requires money to make available water portable.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
