Very small stains or smears, usually unidentifiable but nowadays, any CSI can whip up a computerized printout listing the material(s) that made the trace, smear or stain.

What are base quantities and derived quantities?
Base quantities are the quantities on the basis of which other quantities are expressed. The quantities that are expressed in terms of base quantaties are called derived quantities.
What are derived quantities?
All other quantities which described in terms of base quantities are called base quantities.
Types of physical quantities?
Physical Quantities are of TWO types: 1) Fundamental Quantities. 2) Derived Quantities.
What are the examples of base quantities and derived quantities?
Time ,distance and mass are bass quantities whilevelocity ,acceleration ,force etc are derived quantities.
How many types of quantities?
there are three types of quantities:-1.Scalar quantities - Scalarsare quantities that are fully described by a magnitude (or numerical value) alone.2.vector quantities - Vectorsare quantities that are fully described by both a magnitude and a direction.3.Tensor quantities - tensors are quantities that are fully described by magnitude, direction and the plane thecomponent acts on.
What is the difference between a macro-mineral and a trace element?
A macro mineral is needed in large quantities whereas trace elements are minerals required in small quantities
An element that is essential for the survival of an organism but only in minute quantities?
trace elements
Trace elements are those required by an organism in only minute quantities Which of the following is a trace element that is required by humans and other vertebrates?
iodine
Microorganisms require large quantities of this nutrient for use in cell structure and metabolism?
Trace Element By, Microprocessor Christofer Garcia
What element is a trace element?
Any element which is found only in traces (that's small quantities).
Humans are exposed to trace quantities of toxic chemicals in food (Points: 1)?
YES, it is frequently possible.
Explain Trace metals Heavy metals Give examples?
Poisoning and disease can occur due to human exposure to trace quantities of heavy metals. Common trace metals include mercury (Hg), arsenic (Ar) and lead (Pb).
Is ozone located anywhere else besides the ozone layer?
Yes, ozone is found in trace quantities in earth's atmosphere. it is a greenhouse gas.
What is the most scarce metal?
Francium of the naturally occurring ones along with Promethium and Technetium which have only recently been found in trace quantities in nature
What are the 2 main groups of minerals in food?
The minerals found in food can be categorized into two groups; macrominerals, and trace minerals. Macrominerals are usually found in large quantities in food, and are required in larger quantities for the body. Trace minerals are found in small amounts in food, and are needed in smaller amounts in the diet. Macrominerals: Sodium, potassium, chloride, calcium, phosphorus, magnesium, sulfur. Trace minerals: Iron, zinc, iodide, selenium, copper, fluoride, chromium, molybdenum, manganese.
What are examples of food rich in minerals?
A trace mineral or trace element is an element required in minute quantities by an organism to maintain physiological functioning. Examples of trace minerals are iron, zinc, selenium, fluoride, chromium, copper, iodine, manganese and molybdenum.
What molecules are in mild steel?
A combination of two elements, iron and carbon, where other elements are present in quantities too small to affect the properties, such as trace amounts of sulphur.
