Explain the characteristics scientists use when observing organisms and placing them in the six kingdoms.

Classification of organisms is done while considering many factors such as:

Cell type- whether the organism is prokaryotic or eukaryotic

Cell structure- This includes both the presence and composition of the cell wall

Body type- whether the organism is multicellular or unicellular

Mode of nutrition- the method through which the organism achieves its nutritional requirement, by consuming other organisms (heterotroph) or making its own food (autotroph)

this protocol provides a detailed procedure for total protein extraction for western blot analysis from achieved samples following trizol isolation of rna.

i would go with b

cytokinesis occurs after telophase so that eliminates d

and the entire reason for cytokinesis is for cellular reproduction
