Does shutter speed affect noise?
The slower the shutter speed or higher the ISO, the more noise you get.

The result is poor quality due to the noise in the image.
Does high aperture cause noise?
Noise is caused by not enough light. Higher apertures require longer exposure times. Aperture priority will sacrifice ISO in order to preserve shutter. Hence, not enough light on the sensor.
