Answer:
A. Increase in permafrost thickness
Explanation:
<u>Climate warming (like of 4°C) would increase the active layer thickness (ALT) of permafrost</u>, which can cause changes in the hydrological cycle, ecological processes, and carbon flux in cold regions.

Answer:
A. 28 years
Explanation:
Applying,
R = R'(2ᵃ/ⁿ).............. Equation 1
Where R = Original sample, R' = Sample left after decay, a = Total time taken to decay, n = half life.
From the question,
Given: R = 12 g, R' = 6 g, a = 28 years.
Substitute into equation 1 and solve for n
12 = 6(2²⁸/ⁿ)
12/6 = 2²⁸/ⁿ
2²⁸/ⁿ = 2
Equation the base,
28/n = 1
n = 28 years.
Hence the half-life is 28 years
