Answer:
The correct answer is B. They are a collection of minerals or a body of glass.
Explanation:
The study of rocks needs the observation of their characteristics; its characteristics depend on the properties of the minerals that compose it, its relative amounts and the way in which these were joined to originate the rock. Texture is the external appearance of any rock. It depends on the shape, size and internal arrangement of mineral crystals. Each of these characteristics maintains its specific properties (chemical and physical) in the rock as a whole.
In a rock we can distinguish two types of minerals:
Essential minerals. They are the ones that constitute the nature of the rock and give it its characteristics and properties for being in greater proportion. The lack of one of them would result in the formation of a different rock with different properties.
Accessory minerals These are minerals that appear occasionally in very low proportions within the typical composition of a particular rock. Its presence does not alter the basic characteristics of the rock.
A. freshwater fishing.
my reasoning:
Inside the Middle East, most countries have large supplies of oil, (which helps make the countries rich as they are today because of oil demands), which takes out the options C & D. The Middle East, is located within the Sahara desert, and so can contribute to desert research (B) as well.
So A, is your most logical choice.

Answer:
c. an express contract.
Explanation:
Carmen owns a 2009 Toyota Camry that has been driven 24,000 miles and, to his knowledge, has no mechanical problems. He offers to sell the car to his friend Jamie for $12,000. Jamie accepts Carmen's offer. Jamie and Carmen have <u>an express contract</u>. An express contract is a type of contract in which whose terms of agreement have been clearly stated by the parties involved
. It is unlike an implied contract in which although there are intents of agreement but the terms have not been clearly stated out. Jamie and Carmen have an express contract because Jamie is aware of the conditions of the car and the terms of sale was clearly communicated to him by Carmen and he accepted. Another example of an express contract is are purchase and sales contracts.
