The Texture And Look Of A Microscopic Object
The structure and shape of each type of human cell depends on what function it will perform in the body. For example, red blood cells (RBCs) are very small, flat discs, which allows them to easily fit through narrow capillaries and around sharp corners in the circulatory system to deliver oxygen throughout the body.
The elongated shape of muscle cells allows the contraction proteins to line up in an overlapping pattern that makes muscle flexing possible.
And human sperm cells’ structures allow them to “swim” long distances to reach an egg for fertilization
Organize the lengths below from shortest to longest.
28 dm ,629,000 mm ,1.2 km, 30,277 cm
To answer this, all values should be converted in the same
unit just like in km
28 dm = 0.0028 km
629,000 mm = 0.629 km
1.2 km
30,277 cm = 0.30277 km
So the order is 28 dm, 30,277 cm , 629,000 mm and 1.2 km
Actually, it is INNATE IMMUNITY. That is the proven right answer so be careful.

I hope this is the answer that you were looking for.
