Answers
Answer:
AMOEBA:
While the earliest identified amoebae were approximately 400 to 600 microns in size, both extremely small (between 2 and 3 microns) as well as exceptionally large amoebae (20 cm; visible to the naked eye) have been documented to date. Therefore, amoeba species exhibit a wide range of sizes.
HEN EGG:
They are no longer graded numerically. They are now called large eggs (they weigh about 73g).
OSTRICH EGG:Ostrich eggs are the largest of all eggs, though they are actually the smallest eggs relative to the size of the adult bird — on average they are 15 cm (5.9 in) long, 13 cm (5.1 in) wide, and weigh 1.4 kilograms (3.1 lb), over 20 times the weight of a chicken's egg and only 1 to 4% the size of the female
RED BLOOD CELLS:
7.5 to 8.7 μm (in humans)
