Heterogeneous is a word pathologists use to describe tissue that looks very different from one area of the tissue to the next. Differences in colour, shape, and size can make a tissue look heterogeneous. Heterogeneous can be used to describe the way the tissue looks with or without a microscope.
Is schizophrenia heterogeneous?
Schizophrenia is also often described as a heterogeneous disorder because there are many different symptoms observed, as alluded to previously, and also because there are likely many different underlying causes that are as yet unknown.

What is the difference between homogeneous and heterogeneous?

What does heterogeneous mean in science?
A heterogeneous mixture is simply any mixture that is not uniform in composition – it’s a non-uniform mixture of smaller constituent parts. By contrast, a mixture that is uniform in composition is a homogeneous mixture.
Is Orange Juice homogeneous or heterogeneous?
A) Orange juice contains particles of solid (pulp) as well as liquid; it is not chemically pure. B) Because its composition is not uniform throughout, orange juice is a heterogeneous mixture.
Is macaroni salad is homogeneous or heterogeneous?
Pure substances like table salt (Nacl) can be summed up by a simple chemical formula, but most of the things that we encounter on a daily basis are not pure substances. Macaroni salad is actually a complex mixture, containing thousands of different types of molecules.
Is full fat milk homogeneous or heterogeneous?
Whole milk is actually a heterogeneous mixture composed of globules of fat and protein dispersed in water. Homogeneous mixuters are those in which the components are evenly distributed over the major component/constitute of the mixture.
Is a cup of milk homogeneous or heterogeneous?
Milk, for example, appears to be homogeneous, but when examined under a microscope, it clearly consists of tiny globules of fat and protein dispersed in water. The components of heterogeneous mixtures can usually be separated by simple means.
Is sugar and water a heterogeneous mixture?
The sugar-water is a homogenous mixture while the sand-water is a heterogeneous mixture. Both are mixtures, but only the sugar-water can also be called a solution.
Is sugar and pure water homogeneous or heterogeneous?

Is stainless steel a heterogeneous mixture?
Sea water is a homogeneous mixture of water, table salt and a variety of other compounds, stainless steel is a homogeneous mixture of iron, carbon, nickel and other elements. Heterogeneous: mixtures that are poorly mixed. The substances that are mixed together are easily seen.
Is Rust homogeneous or heterogeneous?
sand and salt: heterogeneous; salt water: homogeneous; pure water: compound; tossed salad: heterogeneous; hydrogen: element; unfiltered air: homogeneous; an apple: heterogeneous; granite: heterogeneous; iron: element; iron with rust: heterogeneous; nitric acid: compound; wood: heterogeneous.
Is soil heterogeneous or homogeneous?
Soil is composed of small pieces of a variety of materials, so it is a heterogeneous mixture. Water is a substance. More specifically, because water is composed of hydrogen and oxygen, it is a compound.
Is Jello homogeneous or heterogeneous?
A colloid is a homogeneous solution with intermediate particle size between a solution and a suspension. Colloid particles may be seen in a beam of light such as dust in air in a “shaft” of sunlight. Milk, fog, and jello are examples of colloids. In contrast a suspension is a heterogeneous mixture of larger particles.
Is chicken noodle soup homogeneous or heterogeneous?
Chicken noodle soup is a heterogeneous mixture. This is because the noodles stay separate from the liquid.
Is pure air homogeneous or heterogeneous?
The air that you breathe is a homogeneous mixture of oxygen, nitrogen, argon, and carbon dioxide, along with other elements in smaller amounts. Because each layer of the Earth’s atmosphere has a different density, each layer of air is its own homogeneous mixture.
