…within the same sentence?
Check your leading, space before paragraph, space after paragraph, and baseline shift settings. It looks to me like your type is set 80 on 45 (which is pretty tight) with some paragraph spacing.
Increase Leading to make more space between lines in the same paragraph. With bullet points as in your example the leading is usually set a bit tight and the Space After (or Before) Paragraph is used to space out the separate items in the list.
