Answer:
C, D.
Explanation:
C: The flowing lava creates extra rock. For example, entire islands are formed via this process of volcanos erupting, lava cooling, repeat.
D: Silt from erosion (erosion itself is considered destructive, but the resulting silt can turn into something constructive.) can build up entire mounds or mountains over time.
Answer:
Ethnoscience attempts to understand how people understand the world and plant systematics attempts to use classification to document evolutionary relationships between organisims
Explanation:
Ethnoscience is a study about how people see the world around them. This study shows how different people understand the nature and life under the influence of different cultures.
On the other hand, systematics shows relationships among living things through a certain period of time. Those relationships are graphically represented by phylogenetic trees or cladograms.
Nicked circle is the reason.
Explanation:
During recombinant DNA technology the gene of interest is ligated to plasmid DNA by excision with molecular scissors or endonuclease enzyme and ligated with enzyme ligase.
Enzyme ligase catalysed by ATP seals the nicks by making phosphodiester bonds in the ds or ss DNA and release of ADP.
The ligation in the plasmid did not occur properly hence the replication is interrupted hence no new plasmids with gene of interest replicated in the ligation carried out.
Answer:
C) specialists.
Explanation:
The finches of the Galapagos Islands would be considered specialists. This is because the finches have diversified in a way in which each species has uniquely evolved to perform a very specific task (eating a particular type of food). Moreover, this process is known as adaptive radiation, as a single lineage (the original finch) undergoes speciation events that eventually fill divergent ecological niches, creating many related species.
