Physical properties are those that an object or trace evidence has with just its physical existence, without altering it in any way with chemicals.
true or false?
: )

TRUE

Explanation:

Those properties that can be observed easily and are measurable can be considered as physical properties. This property does not bring any changes in its chemical composition. Some of the examples of physical properties are boiling point, color, texture, and density.  

On the other hand, the chemical properties are those that can be seen only during the time of chemical reaction, and due to this reaction, the chemical composition of the substance alters. This is what marks the difference between physical and chemical properties.

Hence, the above statement is true.

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.
