A lot of carbon stored inside the Earth may soon re-enter the atmosphere, according to a new, global study on soil-based carbon. The massive release of carbon could be the equivalent of adding another fully industrialized country the size of the United States to the map over the coming decades.
Plants, animals, and microbes absorb much of the carbon dioxide released into the Earth's atmosphere by burning fossil fuels. As these plants and animals die, their carbon-based bodies become part of the soil, storing the equivalent of millions of tons of greenhouse gases in the dirt. As atmospheric carbon dioxide is a primary driver of climate change, some have pointed to this soil absorption as a helpful carbon sink, somewhat alleviating the human-caused warming of the planet. But as surface temperatures continue to rise, a lot of the carbon stored in the soil may be set to re-enter the atmosphere in a big way.
.B) decomposition of organic matter
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.
Answer:
B. positive
Explanation:
Histones are proteins that bind to the DNA in order to form highly compacted structures named nucleosomes, the basic structural units of DNA packaging in eukaryotic genomes. A nucleosome is a segment of DNA wound around an octamer (8) of histones, i.e., two copies each of the histones H2A, H2B, H3, and H4. These histones are positively charged in order to interact with the negatively charged DNA molecule. During transcription, reducing histone positive charge decreases the interaction between DNA and histones in the nucleosomes, thereby opening the chromatin to favor the access of the transcriptional complex and thus facilitates gene expression.
Domain is basically your (X) value.
Ex: (3,7) 3 would be your domain because it is the x value.
