Does MPU-6050 pulls up MPU_SDA and MPU_SCL pins?

I am looking at the schematic for the MPU-6050 Evaluation board - I can clearly see that the SDA and SCL lines going to the User Header for connection to external MCU are pulled up to VLogic/VDD.

However the SCL and SDA pins of the magnetometer are connected to auxilliary MPU_SDA and MPU_SCL pins of MPU-6050 directly with no pull-up resistors connected to these lines. Does MPU-6050 pulls them up internally (and if so, what is the resistance on these lines) or the magnetometer pulls them up internally?

I am planning to use MPU-6050 directly in my design and would like to connect a different magnetometer (Freescale MAG3110) using the passthrough I2C functionality of MPU-6050 - do I need to put pull-up resistors between the MPU-6050 and my magnetometer?

I would greatly appreciate your advise!
