Using the answer from the previous question, if a spherical tumor is not vascularized, how large can it grow (radius, in mm, two significant digits) before the oxygen concentration in the center of the tumor falls to zero? (this is the maximum size that the tumor can grow without vascularization.) the concentration of oxygen in the fluid surrounding it is constant at 0.15 mol/m3, the diffusivity of oxygen in the tumor is 6.2 e-9 m2/s, and the reaction rate of oxygen in the tumor is -0.20 mol/(m3◦s).previous question: a spherical tissue engineered device is being explored. it would be a pellet of radius l containing insulin-producing cells for use as an implant to treat diabetes. this implant would be cultured in a bath with a constant oxygen concentration of co

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.

thats not a question
