[сᴏᴏʟ сяуѕтᴀʟѕ]

but since they grow from two DIFFERENT pieces of potato tuber, shouldn't parents be different?

can u plz explain q13 about soil erosion?

when the farmland is sloping, and there is water from raining , water will take the upper part of the soil with it (soil erosion)
so when changed to terraced fields soil will not move with the rain as there is no slope

Thanks, but in Q28, don't you see some tiny leaves appearing in option C?
And in Q37, shouldn't the key be C, cuz it is only in those two years when the birth rate = death rate (meaning that net population change is zero)

LOL...those poor lil leaves can't photosynthesize

nope...as i said measure the length in between the 2 lines...they should be equal..the years you mentioned, have different lengths...(1957 and 1963 is 0 but between them it's like 0.5 or something)
