Agroup of students decide to repeat the hershey and chase experiment with modifications. they decide to radioactively label the nitrogen in the dna, instead of the phosphate. they reasoned that each nucleotide contains more nitrogen than phosphate, so labeling the nitrogen will provide a stronger signal than labeling the phosphate. what is the flaw in this experimental design?

correct answer: biotic and abiotic limitations

carrying capacity is defined as the total number of an organism who can be supported in a given area within the natural resources limit and without harming or degrading the natural, economic or the cultural environment present for the future generations.

carrying capacity is determined by the limiting factors, which are known to affect the natural resources available. it may include water, nutrients, minerals, space, light etc.
