i believe its B

Explanation:

.Since in solids (such as packed earth) molecules are packed more closely together than in gases (such as air), the speed of sound waves should be faster in solids than in gases.

B. Particles of matter are packed moe tightly in the ground than in the air.

Explanation:

The correct answer is

b. Particles of matter are packed more tightly in the ground than in the air.

Sound waves generally move faster in solids than liquids and gases. The reason is that sound waves are vibrations of the molecules of the medium: therefore, if the particles of the medium are closer together (as in solids), the vibrations can be transmitted faster, and the wave can travel faster. On the contrary, in gases the particles are spread apart, so the vibrations are not transmitted so easily (because there are less collisions between the particles) and the wave travels slower.

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.

The pharynx is the structure in the body that serves as a pathway of both air and food. how does the body make sure that food does not get into the lungs? the salivary glands secrete enzymes that pull food out of the air pathway. the small intestine pushes the air out of the digestive system. the pancreas breaks down food in the air pathway. the epiglottis closes the air pathway so that food will not enter it.
