How are multiple Windows home network interfaces used at the same time?

Question

Computer networks

If you connect a laptop with Windows 10 Home to Wifi, and then to a usb modem, the task manager in the "Performance" tab will show that each network interface is in use. It turns out that the laptop receives data simultaneously from both wifi and usb modem. uTorrent uses two adapters at once and the overall speed is increased. In the browser, if you download 2 files, a separate adapter will be used for each file. The laptop itself is connected to the hotel wifi, the usb modem is a phone connected to the hotel wifi. It turns out two channels to the hotel wifi (limit 5 Mbps)

1. Where is it described how it works? (These are two different IPs or not)

3. Is this distribution of network load across multiple network adapters performed by Windows or an application?
