Explanation:

A homogeneous mixture has a uniform composition throughout. A heterogeneous mixture has a non - uniform composition with visible different parts.

• A glass of soda is a homogeneous mixture as the dissolved carbon dioxide and other substances are uniformly distributed in the liquid.
• Saline is a homogeneous mixture as salt is uniformly dissolved in water.
• A bowl of cereal is a heterogeneous mixture as you can see different components like grains and possibly fruits or nuts.
• Sand is a heterogeneous mixture as it contains different sized particles and possibly different minerals.
• Salad dressing is often a heterogeneous mixture, especially if it has not been well - mixed and you can see oil droplets and other ingredients separately.
• Black tea is a homogeneous mixture as the tea leaves' components are uniformly dissolved in water.
• Mulch is a heterogeneous mixture as it contains different plant materials and possibly other debris in different sizes and forms.
• Chocolate chip cookies are a heterogeneous mixture as you can see the chocolate chips and the cookie dough as different parts.
