Answer:
It's simple really—plants get the materials they need to grow cheifly from air and water! Sunlight provides the energy plants need to convert water and carbon dioxide (CO2), a major component in air, to carbohydrates, such as sugars, in a process called photosynthesis. Hope this is what your looking for!
Explanation:
Brainliest please?
The pelagic zone is where plankton can be found most frequently.
Plankton is chlorophyll-containing photosynthesizing plants that make their own sustenance from carbon dioxide and sunlight.
They are autotrophic aquatic plants. Their roots have a good aquatic life adaptation.
Thus, the pelagic zone is where plankton is most frequently found.

Answer:
The marine industries affected the marine life and ocean water in many ways. When carbon dioxide dissolves in seawater, the water becomes more acidic and the ocean's pH drops. In the past two hundred years alone, ocean water has become 30 percent more acidic and faster than any known change in ocean chemistry in the last million years.

Answer/Explanation:
(1) a mutation in the coding region, resulting in an inactive protein
To check to see if there is a mutation, you could extract the DNA from the cancer cells and then perform PCR to amplify the gene of interest. You could then perform sanger sequencing and compare the sequence to the normal gene to see if a mutation is present. To test the effect of the mutation, you would want to see if an active protein has been formed.
To see if a normal sized protein has been formed, you could perform a western blot, comparing the protein band to the WT protein band. If the protein is absent or much smaller, it is likely not a functional protein.
(2) epigenetic silencing at the promoter of the gene, resulting in reduced transcription.
To check for changes in the epigenetic landscape of the promoter, you could perform chromatin immunoprecipitation by extracting the chromatin from the tumour cells and using antibodies for different chromatin marks to see what has changed between the normal cells and the tumor cells. E.g. H3K9me3, H3K27me3. You would perform a pull down with the antibody of interest and then PCR for your promoter to specifically look at changes at that gene compared to normal cells. To test DNA methylation, you could perform bisulfite sequencing.
To see how transcription is affected, you could extract RNA from the tumor and normal cells, and compare the levels of RNA between the two samples by qRT-PCR
