Answer:
Option B = 60,600 mg (correct option)
Explanation:
First of all we will have an idea which numbers are consider as significant.
1 = All non-zero digits are consider significant figures like 1, 2, 3, 4, 5, 6, 7, 8, 9.
2= Leading zeros are not consider as a significant figures. e.g. 0.02 in this number only one significant figure present which is 2.
3= Zero between the non zero digits are consider significant like 105 consist of three significant figures.
4= The zeros at the right side e.g 3400 are also significant. There are four significant figures are present.
In given options, Option A 60.6 mg have 3 significant figures.
Option B have 5 significant figures.
Option C have 4 significant figures.
Option D have 3 significant figures.
Thus option b is correct option which have more significant figures.
Answer: Option C) The unicellular organism creates a new organism.
Explanation:
Cell division involves the multiplication of cells whereby one cell divides into two daughter cells or offsprings, two divides into four and so on.
In unicellular organisms, cell division could be by the following ways:
- Binary fission in Ameoba
- Budding in Hydra
- fragmentation in Sponges.
Thus, each of these unicellular organisms divides to give rise to new organisms that are similar to their parents
