The step at which the researchers would do at the end of researching Edna is to amplify the amount of DNA.
Option (d);
<u>EXPLANATION:</u>
- The term EDNA means Environmental DNA.
- Invasive species in the waterway are the waterborne plants and animals who can likely cause effects to the human as well as the environment.
- If researchers want to use eDNA to look for invasive species in the waterway, they will first collect a sample.
- After cutting DNA into pieces, DNA would be precipitated in each sample.
- And in the end, the amount of DNA would be amplified in each sample to understand how it would cause harm to the environment.
Answer:
Animalia - multicellular, eukaryotic
Plantae - vacuolate eukaryotic cells, multicellular
Protista - unicellular and multicellular, eukaryotic
Fungi - decomposers, non-motile
Eubacteria - unicellular, prokaryotic
Archaebacteria - no peptidoglycan, glycoproteins and polysaccharides in cell walls.
Hope that helps. :)
None of the provided options are reasonable. <span>comparing nutrient concentrations between the photic zone and the benthic zone can not tell you whether differences in concentrations between the photic and benthic zone are due to uptake by phytoplankton or because nutrients are sinking to the sea bottom and ocean stratification is preventing mixing. The approach of c</span><span>ontrasting nutrient uptake by autotrophs at different locations under different temperatures would not provide useful information on limiting nutrients. but rather uptake rates at different temperatures. It is likely that e</span>xperimentally enriching some areas of the ocean and compare their productivity to that of untreated areas can provide an indication of limiting nutrients, but this is not advisable, as it would have to be done on a large scale, and one cannot be sure of the ecological consequences. Also, because it would not be a controlled experiment, other factors could create 'noise' in the data. The last option, <span>observe antarctic ocean productivity from year to year to see if it changes, also does not help, as there is no correlation between nutrient concentrations using this approach. The best approaches would be either the last approach, but with the additional monitoring of nutrient concentrations, or under a controlled laboratory experiment.</span>
Answer:
Photosynthesis is the answer
