What two examples of physical or behavioral adaptations that exist in the Sahara Desert response to frequent sandstorms?

Two examples of physical or behavioral adaptations that exist in the Sahara Desert response to frequent sandstorms are:

- A protective layer of fur or hair: Many animals that live in the Sahara Desert have a thick coat of fur or hair that helps to protect them from the sand and dust of sandstorms. This fur or hair can also help to keep them warm during cold desert nights.

- Nostril closures: Many animals that live in the Sahara Desert have special adaptations that allow them to close their nostrils during sandstorms. This helps to prevent them from inhaling sand and dust, which can cause respiratory problems.
