Heterogeneous means non-uniform, so mango is arguably heterogeneous; you have the skin, pulp, seed etc. in a mixture, although it is stretching the interpretation of "mixture" when it would be more conventional to consider a single skin, a single seed (mangos have only one seed) and one continuous piece of pulp as discrete parts.
The question also ask about "mango", not " a mango" - which implies it is not about a whole fruit.
(Many homogeneous mixtures are easily separated - a mixture of powdered sugar and chalk, or a bag of green and red marbles, for instance. Although, again, it depends on what level you are considering the "mixture").
mango is a heterogeneous mixture
Avocado is heterogeneous.

Rule of thumb to use, is if it can settle to the bottom of if it or you have to shake it; it is deffinitly heterogeneous.
heterogeneous
A heterogeneous mixture is a mixture of things that can be clearly seen as separate. For example, oil droplets in water, peas in a bowl of soup,Oil in water is also an example of an immiscible solution because the two fluids will not ever mix, you can try to mix oil+water if you shake them vigorously enough and they will then look homogeneous and cloudy for a few seconds, but then they separate again.A homogeneous mixture is one in which the different components are so thoroughly mixed that they cannot be visibly distinguished. For example, proteins and water in a glass of milk, most acids in water, the air we breath, petrol, to name a few.What is "visibly distinguishable" in a mixture depends on your point of view of course: at a fine enough magnification all mixtures will seem heterogeneous, and at a coarse enough resolution all mixtures will look homogeneous.
A pure oil of one chemical formula is not even a mixture. However most oils are mixtures of many oils, and sometimes substances that are not even oils. Also it makes a difference if you are talking vegetable oil, cooking oil, machine oil, crude oil, etc. For example a machine oil with either teflon or graphite added is definitely a heterogeneous mixture.

Cooking oil is an example of a homogeneous mixture, because it has the same consistancy throughout. There is no need to shake it up before using. Shaking is necessary when the contents of a solution settle at the bottom of a solution, such as in Italian salad dressing.
heterogeneous
This a nonhomogeneous mixture.
Raisin Bran is heterogeneous because the substances are not uniform. another example of heterogeneous would be Orange Juice or Muddy water. You have to shake those things up or else the particles will separate. Homo-same; Hetero-different. A raisin muffin is heterogeneous, as it contains several different substances. An example of a homogeneous mixture is pure sugar, as it contains only one substance.
Homogeneous mixture
Oil and vinegar salad dressing is only homogeneous for a brief time when you shake it. The purpose of shaking it is to make it homogeneous before you pour it. After a few minutes of sitting still, it will return to a heterogeneous state.

A heterogeneous mixture is a mixture when two or more substances are mixed together but aren't chemically combined/joined

Heterogeneous will be like Italian dressing because you have to shake it for all its contents to mix evenly on your salad, but if you leave it on the table all the different ingredients will settle back down. Its contents are not evenly distributed so its heterogeneous. Another example is water and oil. The oil always float on water. Homogeneous will be like koolaid because the sugar and water is evenly distributed.
