The ductus venosus on the other hand is a fetal vessel that transports blood from the umbilical vein to the inferior venacava.

It allows most of the blood from the right ventricle to bypass the fetus's fluid-filled non-functioning lungs.

A man is 1.7 m long. A paramecium is 85 µm long. How does the length of the man compare to the length of the paramecium?
NISA [10]

Answer is C. The man is twenty thousand (2 x 10⁴) times larger than the paramecium.

1 meter (m) = 10⁶ micrometers (µm)

Therefore, 1.7 m = 1.7 × 10⁶ µm

Thus, the length of the man compared to the length of the paramecium will be

1.7 × 10⁶ / 85 = 2× 10⁴ .  

Therefore, length of the man is  2× 10⁴ times larger than the length of the paramecium.
