Energy is termed as quantitative property which is transferred to an object so as to heat. Energy cannot be destroyed or created but it can be converted to a form of an object.
There are different forms of energy. For example, kinetic energy which is a moving object, elastic energy which is got by stretching solid objects and stored, chemical energy which is released when fuel is burned.
Inorder for living organisms to stay alive they should have available energy. For example, human gets energy from food. Radiant energy drives ecosystem and earth's climate whereby the earth receives it from geothermal energy and sun.
Biological measurements are the parameters associated with biological systems. An incorrect diagnosis and medical interventions are some measurements due to poor classification.
<h3>What are risk factors?</h3>
Risk factors are the biological, psychological, or social influences that affect the result or the outcome that can be positive or negative. The biological measurement risk factors might include the organism's system.
The poor classification of the biological risk factor can lead to an incorrect diagnosis of the condition followed by medical treatment and procedures that might have side effects.
Therefore, the medical diagnosis and intervention can be some risk factors.

Limulus polyphemus are the source of cells for the LAL test used to detect bacterial contamination of surgical tools.
Limulus amebocyte lysate (LAL) is an aqueous extract of blood cells from the Limulus polyphemus which is used in LAL test. LAL test includes the reaction between LAL and bacterial endotoxin lipopolysaccharide (LPS), which is a membrane component of gram-negative bacteria. LAL test is widely used for the detection and quantification of bacterial endotoxins.
