The correct answer is +/-.
There are different types of interactions and relationships between the various species of an ecosystem. If both species benefit from an interaction, then we talk about a mutualistic interaction which is symbolized by +/+. There are competitive interactions where both of the species are affected negatively and are symbolized as -/-. In this example, while the lion pride is benefited by the interaction, the African wild dog is excluded from specific areas of the ecosystem and therefore the species is disadvantaged. This relationship is symbolized as +/-.
Answer:
inside the phage ghosts outside the bacterial cells.
Explanation:
According to Hershey & Chase- Experiments, the radioisotope 35S is frequently associated with protein since sulfur is a protein component. The radioactive sulfur is absorbed into the protein coat because it already contained sulfur (35S). The radioactive marker 35S was integrated into the Bacteriophage protein coat and remained as phage ghosts outside the bacterial cells.
