Answer: 1800 centimeters is the largest measurement
Explanation:
1800 cm = 0.018 km
2.1 m = 0.0021 km
0.0017 km is the smallest
Answer:
Protons and neutrons have approximately the same mass, about 1.67 × 10−24 grams, which scientists define as one atomic mass unit (amu) or one Dalton. Each electron has a negative charge (−1) equal to the positive charge of a proton (+1). Neutrons are uncharged particles found within the nucleus. hope this helps you :)

The human cell has the largest surface area to volume ratio is Sperm cell or spermatozoa and its ratio is 1.55
<u>Explanation:</u>
Spermatozoa is a uni-flagellar motile sperm cell that basically determines the sex of an offspring. It moves from the haploid male gamete,its contributes in 1/2 nuclear genetic information to diploid.
The surface area of sperm cell is measured by micro-metric method or electron mircographs using stereo-logical method. While the volume will be measured by stereology or radio label volume exclusion method. The volume and surface area inversely proportional to cell size.
