High relative humidity in a brooder house could lead to
Reduced feed intake
Production of dry litter
Build up of pests and diseases
Heat stress
Correct answer is C
High humidity in a brooder house creates a conducive environment for the growth and multiplication of pests and diseases. It can also lead to the development of mould and fungi, which can be harmful to the chicks.
Study the table below and use it to answer the question
| Cost Price (N) | Useful life (Years) | Salvage value (N) | Annual depreciation (N) | Total depreciation |
| 20000 | Y | 5000 | 1000 annum | 15000 |
| 60000 | 10 | 18000 | 4200 annum | Z |
The total depreciation represented by Z in the illustrated table is
N42,000
N78,000
N22,200
N55,800
Correct answer is A
Cost Price (N) = 60000
Salvage value (N) = 18000
Annual depreciation (N) = 4200
Useful life (Years) = 10
The formula to calculate the total depreciation is:
Total depreciation = (Cost Price - Salvage value) / Useful life
Now, let's plug in the values:
Total depreciation = (60000 - 18000) / 10
Total depreciation = 42000 / 10
Total depreciation = 4200
Therefore, the total depreciation represented by Z in the table is N 42,000.

Average rate of evoluton of gas
Total mass of gas evolved during the reaction
Time taken for the reaction to reach completion
Initial reaction rates
Correct answer is B
The total mass of gas evolved during the reaction will remain the same in each case. This is because the amount of marble chips is the same in each case, and the reaction goes to completion. Therefore, the same amount of gas will be produced in each case, regardless of the concentration of the hydrochloric acid.
