Why is limestone considered both chemical and biochemical?

Limestone. Limestone is comprised of calcite and aragonite. It can occur as a chemical sedimentary rock, forming inorganically due to precipitation, but most limestone is biochemical in origin. In fact, limestone is by far the most common biochemical sedimentary rock.

Biotite and muscovite have 1 plane of cleavage in common.

What is metamorphism when it refers to rocks?

Metamorphism is a process of mineral assemblage and texture variation that results from the physical-chemical changes of solid rocks, caused by factors such as crust movement, magma activity, or thermal fluid change in the earth.

What are the most common types of minerals that precipitate to form chemical sedimentary rocks?

Chemical sedimentary rocks are formed by direct chemical precipitation from water. While some limestones and cherts may form in this manner, evaporite deposits consisting of halite, gypsum, and other salts are the most common.

What are the three types of sedimentary rocks?

Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans.

What limestone is used for?

Limestone is a source of lime (calcium oxide), which is used in steel manufacturing, mining, paper production, water treatment and purification, and plastic production. Lime also has major applications in the manufacture of glass and in agriculture.

Which rock type may be both a chemical and a biochemical sedimentary rock quizlet?

Limestone can form as either a chemical rock made of calcite or as a biochemical rock made of fossils that are, in turn, made of aragonite or calcite.

What is the difference between chemical and organic limestone?

Clastic sedimentary rocks are made of sediments. The sediments differ in size. Chemical sedimentary rocks are made of minerals that precipitate from saline water. Organic sedimentary rocks are made from the bodies of organisms.

Is limestone a chemical sedimentary rock?

The most common chemical sedimentary rock, by far, is limestone. Others include chert, banded iron formation, and a variety of rocks that form when bodies of water evaporate. Biological processes are important in the formation of some chemical sedimentary rocks, especially limestone and chert.

What is the chemical composition of limestone?

calcium carbonateLimestone is a sedimentary rock that is dominantly composed of the calcium-bearing carbonate minerals calcite and dolomite. Calcite is chemically calcium carbonate (formula CaCO3). Dolomite is chemically calcium-magnesium carbonate (formula CaMg(CO3)2).

Where should a specimen be collected from?

The specimen should be collected from the side of the selected finger to avoid painful fingertip sticks.

What chapter is Diagnostic Testing?

Start studying Chapter 15: Specimen Collection and Diagnostic Testing. Learn vocabulary, terms, and more with flashcards, games, and other study tools.

What tip do nurses use to collect anaerobic specimens?

To collect an anaerobic specimen deep in a body cavity, the nurse uses a sterile syringe tip.

What is the red spot on stool?

When blood in the stool is bright red, the site of bleeding is most likely from the lower gastrointestinal tract.

When is a midstream urine specimen collected?

A midstream urine specimen is collected after voiding is initiated and before it is completed.

When is the best time to collect sputum?

Early morning before a meal is the best time to collect a sputum specimen.

Can a nurse collect a wound culture from old drainage?

The nurse should not collect a wound culture from old drainage.

What are diagnostic specimens?

Specimen shipments in the United States and internationally are regulated under either the hazardous materials regulations (US) or dangerous goods regulations (international). Specimens shipped as part an evaluation of an acute gastroenteritis outbreak are considered to be “diagnostic specimens” or “clinical specimens.” Diagnostic specimens are classified as hazardous materials (risk groups 2, 3 and 4 under 2004 regulations; or Category B under 2005-2006 regulations) and therefore require packaging that meets Department of Transportation (DOT) (domestic shipments in the United States) Transportation of Hazardous Materials Regulations (HMR) and International Air Transport Association (IATA) (international air shipments worldwide) Dangerous Goods Regulations (DGR).

What is patient specimen?

Patient specimens – human or animal materials, collected directly from humans or animals including, but not limited to, excreta, secreta, blood and its components, tissue and tissue fluid swabs, and body parts being transported for purposes such as research, diagnosis, investigational activities, disease treatment and prevention

What are the two categories of infectious substances?

IATA DGR classifies infectious substances into two categories, Biological substance category A and Biological substances category B:

When ice or dry ice are used, must it be placed outside the secondary packaging or in the outer container?

When ice or dry ice are used, it must be placed outside the secondary packaging or in the outer container or an overpack

How many feet does a package have to be to pass a drop test?

Each complete package must be capable of withstanding a 4 foot (1.2 meter) drop test outlined in IATA and DOT regulations.

What is an infectious substance?

Definitions: Infectious substance – a material known to contain or are reasonably expected to contain pathogens. Pathogens are defined as microorganisms (including bacteria, viruses, rickettsiae, parasites and fungi) and other agents such as prions that cause disease in human or animals.

Do you need an infectious substance label for a diagnostic specimen?

Diagnostic specimen shipments DO NOT require an Infectious Substance label, Shipper’s Declaration for Dangerous Goods or emergency response information.

What is a diagnostic specimen?

Diagnostic specimen means any human or animal material, including excreta, secreta, blood and its components, tissue, and tissue fluids being transported for diagnostic or investigational purposes, but excluding live infected humans or animals. A diagnostic specimen is not assigned aRISK GROUP TABLEUN identification number unless the source patient or animal has or may have a serious human or animal disease from a Risk Group 4 pathogen, in which case it must be classed as Division 6.2, described as an infectious substance, and assigned to UN 2814 or UN 2900, as appropriate. Assignment to UN 2814 or UN 2900 is based on known medical condition and history of the patient or animal, endemic local conditions, symptoms of the source patient or animal, or professional judgement concerning individual circumstances of the source patient or animal.

The proper shipping name "Biological substance, category B", " Diagnostic specimen " or "Clinical specimen" in letters at least 6 mm high shall be marked on the outer package adjacent to the diamond-shaped mark.

Why is ELISA not useful for diagnostic testing?

IgG detection by ELISA in a single serum sample is not useful for diagnostic testing because it remains detectable for life after a dengue virus infection.

What test is performed for dengue?

If infection is likely to have occurred in a place where other potentially cross-reactive flaviviruses circulate, both molecular and serologic diagnostic testing for dengue and other flaviviruses should be performed.

Can PRNTs detect IgM?

PRNTs can resolve false-positive IgM antibody results caused by non-specific reactivity, and, in some cases, can help identify the infecting virus. However, in areas with high prevalence of dengue and Zika virus neutralizing antibodies, PRNT may not confirm a significant proportion of IgM positive results.

Is a rRT-PCR test a confirmation of dengue?

Presence of virus by rRT-PCR or NS1 antigen in a single diagnostic specimen is considered laboratory confirmation of dengue in patients with a compatible clinical and travel history.

Is IgM a confirmed infection?

IgM in a single serum sample strongly suggests a recent dengue virus infection and should be presumed confirmatory for dengue if the infection occurred in a place where other potentially cross-reactive flaviviruses (such as Zika, West Nile, yellow fever, and Japanese encephalitis viruses) are not a risk.
