Answer:
D
Explanation:
1. As given, the overall genome contain 50% G+C.
And the concept is that G is always pairs with C.
and A is always pairs with T.
So, in a dsDNA, A+G= T+C
2. As there that, there is a cluster of genes comprising about 20,000 bp that is 64% G + C so this so that the 20,000 bp segment is a recent acquisition via horizontal gene transfer.
Actually, it is INNATE IMMUNITY. That is the proven right answer so be careful.
251 million years ago, the Permian extinction occurred. It is the widest and most massive extinction that wiped out 85-90% of marine species and 70% of land vertebrates at that time. There were recorded low oxygen levels in deep and shallow oceans, extreme shift in the carbon cycle, massive eruption of a basal salt volcano in Siberia and the consecutive global warming that occurred evidently ended early prehistoric life.
Answer:
310
third and last option
Explanation:
Well i subtracted 450 by 140 and got 310
Then those ones make the most sense so
Hope this helps!
