I am pretty sure that the layer in figure 4-1 which forms the cap rock for the oil trap is the layer  F that shows an example of stratigraphic traps that includes unconformity, lens, pinch-out in which you can see how t<span>he oil is stuck inside the porosity of the rocks. 
Do hope you will find it helpful! Regards.</span>
        
             
        
        
        
If a bacterium cannot use citrate agar will not change its color (stays green). On the other hand, if bacteria have the ability to use citrate, the medium will change its color from green to blue.
This happens because citrate agar contains pH indicator such as bromothymol blue which transforms from green to blue in alkaline conditions.

Its the person's offspring have mutated skin.
because for a mutation to be passed down to an offspring mutation has to happen in the sex cells. so that is the least likely to happen.
since the other may happen for example.
skin cancer: i am not sure how but definitely sure that it is the second least that is gonna happen. (trust me)
reduced functioning of skin cell yes.: if there are changes in the nucleotides which can give a diff amino acid.
and no change. cuz if the mutation occurs but the nucleotides still codes for the same amino acid then there is no problem!!
