Answer:
sunlight
Explanation:
The plants and animals get confused with the artificial light that is used by the human beings.
C) the heat transfer to the boiler
Frost wedging
Explanation:
Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils.
Some agents of weathering are wind, water, glacier and gravity.
- In physical weathering, rocks are broken down mechanically into smaller bit.
- Freezing and thawing allows for the propagation of physical weathering.
- Water within cracks will expand when they freeze significantly.
- This will further expand and widen the cracks.
- When the ice thaws the stress is relieved.
- When the process continues on and on over the year, a rock will eventually break down.
- This is common around the temperate and polar regions.

according to this reaction:
by using the ICE table:
CO(OH)2 → CO2+ + 2OH-
intial 0 0
change +X +2X
Equ X 2X
when Ksp = [CO2][OH-]^2
by substitution:
3.6 x 10^-16 = X * (2X)^2
3.6 x 10^-16 = 4 X^3
∴X = 3.88 x 10^-6 M
Answer:
option A is correct a bond formed by transfer of electron
