I've seen this question before, I think you have incorrect choices
The correct answer is: DNA polymerase pairingnew As with Gs.
not Cs with Gs .
C) According to Lamarck, long necked giraffes evolved because they spent the majority of their time stretching their necks and this trait was passed down to offspring; according to Darwin, Giraffes with long necks had the advantage in the environment and survived, reproduced, and passed this trait on to offspring.
Answer:
Mutation
Explanation:
Mutation creates new genetic variation in a gene pool. It is how all new alleles first arise.
The correct answer to two proteins that share 30% amino acid identity are 30% homologous is false.
Although homology can be inferred from excess similarity and excess similarity can be recognized from statistical estimates (E()-values), most researchers prefer to describe similarity in terms of "percent identity." Although it is a common rule of thumb that two sequences are homologous if they are more than 30% identical across their entire lengths (much higher identities are seen by chance in short alignments), the 30% criterion misses many easily detectable homologs. While 30% identical alignments over more than 100 residues are almost always statistically significant, many homologs with E()-values 1010 that are not 30% identical are readily found. As a result, E()-values and bit-scores (described below) are far more useful for inferring homology.

It IS NOT A because after a fire, soil remains, so it would be secondary, not primary. D is INCORRECT because after a volcano, only rock is left so it is primary succession, not secondary.
If you can post the picture I could tell you the correct answer.
