What is the difference between API gateway and ESB?
An API gateway is a server that acts as a single entry point into a system, allowing multiple APIs or microservices to be accessed through one interface. Essentially, it’s like a door that sits between the application layer and the backend services layer. It handles many of the tasks that a server would normally handle, such as authentication, routing, and rate-limiting.
Enterprise Service Bus (ESB) is a computer-based architecture that simplifies the development and maintenance of large-scale systems through service-oriented integration. It acts as an intermediary between two applications and provides a consistent way to coordinate communication, allowing them to interact in a loosely coupled manner. This enables components of different systems to easily communicate with one another and makes it easier to manage data integration across multiple systems.
What is the timely filing limit BCBS?
For most Blue Cross Blue Shield health insurance plans, the timely filing limit is typically 12 months after the date of service. This means that claims must be filed within 12 months of the date of service in order to be considered for payment.

What is the evolution of oxygenic photosynthesis?
The evolution of oxygenic photosynthesis is thought to have occurred in a series of steps. The first step is believed to have been the emergence of a form of non-oxygenic photosynthesis that used hydrogen sulfide instead of water as a source of electrons. This was then followed by the acquisition of oxygen-evolving photosynthesis and the development of an oxygen cycle. This ultimately led to the production of energy-rich oxygen and allowed photosynthetic organisms to begin to spread into modern niches. Additional steps likely included the expansion of accessory pigments as well as the development of chemiosmotic electrochemical gradients. Ultimately, this evolutionary process allowed for the oxygenation of the atmosphere and enabled the radiation of diverse photosynthetic organisms.
