Q. Arrange the following cells in an ascending order of their size and select the correct option I. Ostrich eggs II. Mycoplasma III. Bacteria IV. Human RBCs
A) II$\rightarrow$III$\rightarrow$IV$\rightarrow$I
B) I$\rightarrow$IV$\rightarrow$III$\rightarrow$II
C) II$\rightarrow$I$\rightarrow$IV$\rightarrow$III
D) I$\rightarrow$II$\rightarrow$IV$\rightarrow$III
Explanation
(i) Ostrich egg – 170 $\times 150\ \mu m$ (ii) Mycoplasma – 01 – 0.5 $\mu m$ (iii) Bacteria – 3 - 5$\ \mu m$ (iv) Human RBCs – 7 $\mu m$ So, the arrangement in ascending order is Mycoplasma $\rightarrow$ Bacteria $\rightarrow$ Human RBCs $\rightarrow$ Ostrich egg
