Five new species of bacteria were discovered in Antarctic ice core samples. The nucleotide (base) sequences of rRNA subunits were determined for the new species. The table shows the number of nucleotide differences between the species

creative diagnostics provides a protocol for total protein extraction based on ripa which is widely used.

i was thinking 4.0 v hope this

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

hello

answer: collecting information/data

reason: the student is going around and asking people questions to collect data

i hope this
