In this task, you will be given sentences in which you have to recognize the name of the body cells. A cell is a mass of cytoplasm that is bound externally by a cell membrane. Usually microscopic in size, cells are the smallest structural units of living matter and compose all living things. Although there might be several correct answers, you need to write one of them.

Q:  Isolated X . laevis oocytes incubated in medium containing 25 microgram DNA / ml labeled with either 125I , 32P or 14C and from three different sources ( bovine , E . coli and X . laevis ) , incorporated the label at an average rate of 0 . 11 ng . mm - 2 . hr - 1 .

A: oocytes

Q:  Inhibition of platelet aggregation was also observed with the N - terminal fragment of lactotransferrin ( residues 3 - 281 ; 50 % inhibition = 2 microM ) and with CFQWQRNMRKVRGPPVSC synthetic octodecapeptide ( residues 20 - 37 ; 50 % inhibition = 20 microM ) corresponding to one of the two external loops ( residues 28 - 34 and 39 - 42 ) where we recently located the receptor - binding site .

A:
platelet
