Well this is simple if just mutiply 10x4 and get 40x. hope this helped.
Answer:
Wallace Line
Explanation:
Wallace Line is a boundary line which is a transitional zone between Asia and Australia. This boundary drawn by the British naturalist Alfred Russel Wallace in 1859. This boundary restricts the transferring organisms such as flora and fauna from Australia to Asia. So that's why kangaroos, wombats, and koala bears are only present in Australia not in the continent of Asia.
DNA consists of four nitrogenous bases: A, T, C, and G. Because A and T form a pair and C and G form a pair, the percentage composition of A is equal to T and the percentage composition of C is equal to G. This is called Chargaff's Rule.
In this sample, 20% is T. Because the percent composition of A is equal to T, we can expect 20% to also be A. That means that A and T make up 40% of the sample. That leaves 60% of the sample as C and G. The percentage composition of C must be equal to G, so divide 60% by 2 to get 30% G and 30% C.
So the answer is 30%.
