How does the double-helical structure of DNA explain how the molecules can be copied or replicated? A. Because of base pairing, each strand has all the information to serve as a template for the other strand
B. Each strand receives the information from the DNA polymerase attached to the replication fork
o
C. The nitrogenous bases on one strand are copied to the other strand
D. The nitrogenous bases line up on each strand and are attached to each other

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
