A covenant or agreement between two or more persons, with a lawful consideration or cause. Jacob. A deliberate engagement between competent parties, upon a legal consideration, to do or abstain from doing, some act. Wharton.
Enhancing means that the mass brightens up with contrast, meaning that there is a lot of blood vessels feeding the mass. These are imaging terms that radiologists use to describe a picture. <br /><br /> Inhomogeneous means that the whole mass does not look the same; the best I can describe is that it looks speckled. For example, a cyst that is filled with fluid will be homogeneous. Every part of what's inside the cyst will look identical, because it's just fluid in there.
Only one phase of matter is present in a homogeneous mixture. A heterogeneous mixture is a mixture where the components of the mixture are not uniform or have localized regions with different properties.he difference between heterogeneous and homogeneous mixtures is the degree at which the materials are mixed together and the uniformity of their composition. A homogeneous mixture is a mixture where the components that make up the mixture are uniformly distributed throughout the mixture.
