a 2 x 102
b 2 x 103
c 0.7 x 101
d 6.67 x 102

Answers

  1. The bacteria is about 6.67 * 10⁻³ smaller than the amoeba cell

    What is an equation?

    An equation is an expression that shows the relationship between two or more numbers and variables. An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.
    The  length of a bacterial cell is about 3 x 10⁻⁶ m, and the length of an amoeba cell is about 4.5 x 10⁻⁴ m, hence:
    Ratio of bacteria to amoeba =  3 x 10⁻⁶ m / 4.5 x 10⁻⁴ m = 6.67 * 10⁻³
    The bacteria is about 6.67 * 10⁻³ smaller than the amoeba cell
