Fill in the blanks
Qualitative comparisons between the growth of the living system can be in two ways:
(i) Measurement and the comparison of total growth per unit time is called the ..a…growth rate.
(ii) The growth of the given system per unit time expressed on a common basis, eg. per unit initial parameter is called...b.... growth rate

Options

A. a - absolute , b - relative
B. a - relative , b - absolute
C. a - arithmetic , b - geometric
D. a - geometric , b - arithmetic

Answer

To solve the question, we need to fill in the blanks regarding the types of growth rates in living systems.

1. **Understanding the first blank (a)**:
- The question states, "Measurement and the comparison of total growth per unit time is called the ___ growth rate."
- This refers to the total amount of growth observed over a specific period. The term that fits here is "absolute."
- Therefore, we fill in the first blank with "absolute."

2. **Understanding the second blank (b)**:
- The question continues, "The growth of the given system per unit time expressed on a common basis, e.g., per unit initial parameter is called ___ growth rate."
- This describes a growth rate that is normalized to a specific parameter, allowing for comparison across different systems. The term that fits here is "relative."
- Therefore, we fill in the second blank with "relative."

Putting it all together, we can complete the statement as follows:

Qualitative comparisons between the growth of living systems can be in two ways:
(i) Measurement and the comparison of total growth per unit time is called the **absolute** growth rate.
(ii) The growth of the given system per unit time expressed on a common basis, e.g., per unit initial parameter is called **relative** growth rate.

### Final Answers:
a) absolute
b) relative
