Within a double-stranded DNA molecule, adenine forms hydrogen bonds with thymine, and cytosine forms hydrogen bonds with guanine This signifies <u>determining the type of protein produced</u> 
DNA's unique structure enables the molecule to copy itself during cell division. The double-helix shape allows for DNA replication and protein synthesis to occur. Each of the two strands in double-stranded DNA acts as a template to produce two new strands. 
Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).

Answer:
Organisms depends on physical and biological factors of an ecosystem.
Explanation:
Biological and physical changes cause shift in an ecosystem's populations because the population of organisms depends and greatly affected from the environmental factors such as temperature, moisture etc. These environmental factors causes change in the physical features of an ecosystem so when these changes occur in physical factors, it greatly affected the population of organisms.
