-
Place any list of items at the end of the sentence

Use passive

when the identity of the agent (experimenter) is less important than the action (experiment)

Blood samples were drawn.
-
for variety (when the same agent is carrying out all the actions)
-
for modesty
-
by convention (e.g., first person pronouns I, my, me are rare in scientific papers)
-
to improve cohesion and coherence: information flow (Old -> New information)
Use both Passive and Active Sentences
