Compared to small cells large cells have more trouble

large cells have more suface area so it will take the fluids and molecules entering a longer time. So they will have trouble moving needed materials in and waste products out. Hope this helped have a great day! :)

plz mark me as brainliest

moving needed materials in and waste products out.

have a wonderful day

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
