Answer & ExplanationAnswer: A) The most commonly thought of hazard in construction. This hazard includes radiation, extreme temperatures, noise, and vibration.
Explanation:
A physical hazard is defined as "A factor within the environment that can harm the body without necessarily touching it."
Vibration and noise are examples of physical hazards.
Physical hazards include but aren't limited to electricity, radiation, pressure, noise, heights and vibration amongst many others.
Hemopoiesis begins in the red bone marrow, with hemopoietic stem cells that differentiate into myeloid and lymphoid lineages.
Myeloid stem cells give rise to all the other formed elements, including the erythrocytes; megakaryocytes that produce platelets; and a myeloblast lineage that gives rise to monocytes and three forms of granular leukocytes: neutrophils, eosinophils, and basophils.

An ELISA test may be used to diagnose: HIV, which causes AIDS.
An ELISA also called EIA, is a test that detects and measures antibodies in your blood. Antibodies are proteins that your body produces in response to harmful substances called antigens.
Excretion rates of drugs vary greatly depending upon:
* The type of drug taken.
* The medical condition of the person who took the drug.
Nonvolatile drugs are excreted in the body through renal excretion or through kidneys and bladder by means of urine. Other drugs are excreted either by means of sweat, bile, milk, saliva or other body fluids.
