Students love us — and so will you.
The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.
This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.
Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Whale flippers and human arms have similar bone structures despite different functions. This evidence of common ancestry is known as:
- Whale flippers and human arms have similar bone structures despite different functions. This evidence of common ancestry is known as: — Homologous structures
- The presence of a pelvic bone in modern whales, which do not have hind legs, is an example of which type of evolutionary evidence? — Vestigial structures
- Researchers compare the nucleotide sequences of a highly conserved gene across four species. Which finding would best support a recent common ancestry? — High degree of sequence homology
