Answer:
The two main DNA lesions formed by exposure to UVB are cyclobutane pyrimidine dimers (CPD) and 6-4 pyrimidine pyrimidone photoproducts (6-4PPs), and its Dewar isomers.
What question are you talking about?
You can figure it out by looking at a sequence of rocks to try to decipher the times that an event occurred relative to the other events represented in that sequence. The relative age of a rock then is its age in comparison with other rocks. If you know the relative ages of two rock layers, (1) Do you know which is older and which is younger? (2) Do you know how old the layers are in years? so yeah séquences haha
Answer:
populations 1 and 2 will most likely survive.
Explanation:
so here's my thinking- seeing as how population 1 only has seals with thin blubber they will automatically survive because they won't need to adapt to the environment. but population 2 has both thin and thick blubbered seals and seeing as how the thick blubbered ones will most likely just die out the thin blubbered ones will 'take over'
good luck :)
i hope this helps
have a nice day !!
