Explanation:
<u>Answer</u>: Option b) 2
<u>Explanation</u>:
- Significant figures are the digits which play a role in defining a measurement that is they carry some meaning.
- There are <em>three</em> essential rules to find out the significant figures in a given number:
- <u>Rule 1</u>: Non-zero digits such are always significant.
- <u>Rule 2</u>: The zeroes after a non-zero number in decimal are also significant. An example is if the number is 0.0500 then the zeroes after 5 are considered significant, however, the zeroes before 5 are not significant.
- <u>Rule 3:</u> The zeroes placed between any two significant digits are also considered as significant e.g in 202 the zero is significant.
- Therefore, in the number 0.020 km, there are <em>two</em> significant digits, one is 2 and the other is the last zero placed after 2.

Both the mother and father contribute about the same amount of genetic material to their offspring, but it's not quite 50/50. Taking humans as an example, both parents contribute the same amount of genetic material for 22 of the 23 chromosome pairs, but the 23rd pair that determines gender (the X and Y chromosomes) are of different size. So for female children, both parents contribute about the same amount, but for male children, the mother contributes a larger portion since the X chromosome is quite a bit larger than the Y chromosome from the father. Another area in which the contribution differs is the mitochondrial DNA which is contributed solely by the mother. For mammals, this is about 1% of the total genetic material.</span>
