How do components of a DNA molecule influence its physical properties? Deoxyribose and phosphate, linked by phosphodiester bonds, form repeating units to make up the backbone of DNA.
Deoxyribose molecules, nitrogenous bases, and phosphate side chains are linked by glycosidic bonds to give DNA its helical shape.
Nitrogenous bases and phosphate groups are linked by peptide bonds and then folded to give DNA its helical shape.
Nitrogenous bases have a phosphate bound to its 3' end and a deoxyribose bound to its 5' end to form the backbone of DNA.

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up

is this a question? wassup

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms

the answer is d p: cell, q: organ, r: organ system, s: tissue
