you find a way to attach either a red or green fluorescent dye to nucleotides. double-stranded dna molecules with both strands labeled red fluoresce red, those with both strands labeled green fluoresce green, and those with one strand labeled red and the other green fluoresce yellow. you grow human cells in the presence of "red" nucleotides until both dna strands of all chromosomes fluoresce red. you then allow one round of dna replication in the presence of "green" nucleotides. what pattern of fluorescence do you expect to see in the sister chromatids of each chromosome?

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.

i won't lie i don't know so go online and ask google thats what i do

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
