Answer: pathogen–host coevolution
Explanation:
A major driver of evolution is Reciprocal coevolution between host and pathogen. Rather than pathogen, one-sided adaptation to a nonchanging host, high virulence specifically favoured during pathogen–host coevolution. In all of the independent replicate populations under coevolution, the pathogen ( B. thuringiensis ) genotype BT-679 with known nematocidal toxin genes of C. elegans and high virulence specifically swept to fixation but only some of them go under one-sided adaptation,
so relative change in B. thuringiensis virulence was greater than the relative change in C. elegans resistance is due to the elevated copy numbers of the plasmid containing the nematocidal toxin genes

I think it’s B, but i could be wrong
Answer and Explanation:
When viewing the image of Sam's backyard, we can see the occurrence of chemical and physical weathering. Physical weathering is caused by the impact of water on rocks, which promotes the breakdown of rock particles. The chemical weathering is also caused by the water that I contact with the rock react with its elements causing chemical reactions that modify the rock.
Regarding erosion, we can consider the erosion by gravity that is common in mountainous regions, like the one shown in the photo. This type of erosion promotes the loss of mass of the rock due to the detachment and rolling of rock particles, due to gravity. We can also notice the rain erosion, created by the impact of water on the rock that detaches the fragments and transports them to other places.
1. The right answer is in a discontinuous manner.
During DNA replication, the DNA polymerase synthesizes complementary DNA by mating on both strands, since the two strands are antiparallel, the replication is bidirectional, which means that one of the two strand is synthesized in a direction opposite to that of the direction of the enzyme, to do this, the DNA polymerase is obliged to synthesize DNA in the form of small fragments which are called Okazaki fragments, and its synthesized discontinuously (these fragments are not glued together by phosphodiester liasons, it is only after that another enzyme will intervene to ligate these fragments (DNA ligase).
