Biological realm..............
Forward spatter is the blood that is ejected out of the exit wound,going the same direction as the bullet.back spatter is the blood ejected out of the entry wound,travelling against the line of fire and towards the shooter.
When a mutation has an effect that helps a species adapt to an environment, and specimens of both genders have it, it will end up taking over, causing evolution to gradually happen.
Alright.
So the picture is a little hard to see, so bare with me.
Evaporation is where the water is coming out of the ocean up into the air.
I think that is rain happening above the mountain? If so, that is precipitation.
The little river thing coming out of the mountain is runoff.
I cant really see much else on the picture though, so you might need someone else to help you there.
Answer:
The correct answer is option a, that is, the thrM and thrN would be transcribed at high levels in comparison to non-mutant.
Explanation:
Based on the given information, in the existence of thorain the expression of thrM and thrN will be prevented as thorain functions as a negative regulator. In case, if the gene, which codes for thorain, that is, thrL gets mutated, the coding for the functional thorain would get prevented.
With the encoding of the non-functional thrL protein, there would be an enhancement in the expression of thrN and thrM genes and it will get transcribed at higher levels in comparison to the non-mutant or the wild-type.
