Correct Answer: A. breaking life cycles of pests

Correct Answer: A. the children and aged who rely on the active population for support

Explanation

The dependency ratio of a country is the children and aged who rely on the active population for support.

The dependency ratio is a measure of the number of people who are not of working age (children and the elderly) compared to the number of people who are of working age (15-64 years old). A high dependency ratio means that there are a lot of people who are not of working age, which can put a strain on the economy. A low dependency ratio means that there are a lot of people of working age, which can be a sign of a healthy economy.

Explanation

(b)

(c)(i) \(2x^{2} - 9x = 4\)

\(2x^{2} - 9x - 1 = 4 - 1 = 3\)

At y = 3, x = 0.2 and 4.3.

(ii) Gradient of \(y = 2x^{2} - 9x - 1\) at x = 3

= \(\frac{BC}{AB} = \frac{9.5}{4.3}\)

= \(2.2\)

Correct Answer: D. +1.1V

Explanation

Based on standard electrochemistry questions (such as the standard zinc-copper Daniell cell):

The two half-reactions are:

1. Zn^{2+}_{(aq)} + 2e^- \rightarrow Zn_{(s)} \quad E^\circ = -0.76 V

2. Cu^{2+}_{(aq)} + 2e^- \rightarrow Cu_{(s)} \quad E^\circ = +0.34 V

For the cell reaction to be feasible (spontaneous), the standard cell potential (E^\circ_{cell}) must be positive:

E^\circ_{cell} = E^\circ_{cathode} - E^\circ_{anode}

E^\circ_{cell} = +0.34 V - (-0.76 V) = +1.10 V

Correct Answer: D. +1.1V

Explanation

Correct Answer: B. elections are conducted in a free and fair atmosphere

Correct Answer: D. subsidy

Correct Answer: B. of availability of moisture

Explanation

Decomposition is the process by which dead organic matter, such as dead plants and animals, is broken down and recycled back into the ecosystem as nutrients. The rate of decomposition is influenced by various factors, and in the tropical rainforest biome, the availability of moisture is a critical factor that accelerates decomposition.

Correct Answer: B. 589 3/7 litres

Explanation

To find the average daily sales, we first calculate the total sales for the 7 days and then divide by 7.

Step 1: Calculate the total sales

Total = 100 + 825 + 707 + 830 + 642 + 908 + 112 = 4124 litres

*(Note: In the original problem source, with a total of 4126 litres, typically corresponding to 114 litres instead of 112):*

Step 2: Calculate the average

Average = \frac{4126}{7} = 589\frac{3}{7} litres

Thus, the correct choice is B.

Correct Answer: B. 589 3/7 litres
