#1. What shape is Pluto’s orbit around the Sun?

Pluto’s orbit is highly elliptical, so this dwarf planet’s orbit looks quite ‘squashed’ compared to many planets with more circular orbits.

#2. Which of these foods typically includes gluten?

Gluten acts like a type of ‘glue’ that holds food together, and it can be found in wheat, barley and rye. While rye bread tends to have a lower gluten content, it’s not gluten free. If you need to avoid gluten, always check food labels as it can be found in unexpected places.
