Answer:
Explanation:
Deoxyribonucleic acid is said to contain instruction for species characteristics because it carries the information that characterize an individual.
DNA are made up of Nitrogenous bases that are unique codes specify by an individual and no two person has the same the DNA.
Genes are genetic information or instruction that specify an individual. it is located in the chromosome in the nucleus. DNA contains gene which helps to make molecules called proteins. It is the basis of all inheritance and the expression of the gene is what produces the phenotype that is visible.
The reactants of photosynthesis are water, carbon dioxide and light energy.<span>Plants use these reactants to make the food that is essential for plant growth.</span>
Answer:
The answer is sponge
Hope this helped mark BRAINLEST!!!
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>
