Red blood cells typically have a diameter of about 7.5 micrometers, which is equivalent to 7.5 x 10^(-6) meters. To express this number in standard notation, we can write it in decimal form:
7.5 micrometers = 0.0000075 meters.
Since none of the provided options directly match 0.0000075, we need to consider the closest possibilities in the context of standard notation:
The only viable option from the list given is that we are aiming for a value that represents a positive decimal in the range close to the values listed. Based on the choices given, the most reasonable closest match is:
B. 0.0000008 (though still not an exact match to the number in consideration, but closest among the options provided).
None of the options perfectly represent the typical diameter of a red blood cell. For better accuracy, you might highlight that the given options don’t directly reflect the actual standard metric for red blood cell diameter.
