Biological agents are, of course, highly host-specific.

Biological warfare ( also known as germ warfare ) is the use of biological toxins or infectious agents such as bacteria, viruses, and fungi with intent to kill or incapacitate humans, animals or plants as an act of war.

Biological agents are relatively easy to obtain by terrorists and are becoming more threatening in the U. S., and laboratories are working on advanced detection systems to provide early warning, identify contaminated areas and populations at risk, and to facilitate prompt treatment.

The US military has specialized units, which can respond to a bioterrorism event ; among them are the US Marine Corp's Chemical Biological Incident Response Force and the U. S. Army's 20th Support Command ( CBRNE ), which can detect, identify, and neutralize threats, and decontaminate victims exposed to bioterror agents.

According to a International Committee of the Red Cross review of the Biological Weapons Convention, " Toxins are poisonous products of organisms ; unlike biological agents, they are inanimate and not capable of reproducing themselves.

Biological agents such as parasites, microorganisms, plants and animals can have varied effects when exposed to the skin.

ACGIH establishes the Threshold Limit Values ( TLVs ) for chemical substances and physical agents and Biological Exposure Indices ( BEIs ).

Today's list of TLVs includes over 600 chemical substances and physical agents, as well as over 30 Biological Exposure Indices for selected chemicals.

( The use of biological agents to kill crops may be illegal under the Biological Weapons Convention of 1975.

Biological agents, such as Cetuximab have recently been shown to be effective in the treatment of squamous cell head and neck cancers, and are likely to have an increasing role in the future management of this condition when used in conjunction with other treatments.

Biological Anthropology and Physical Anthropology are synonymous terms to describe anthropological research focused on the study of humans and non-human primates in their biological, evolutionary, and demographic dimensions.

Biological anthropologists are interested in both human variation and in the possibility of human universals ( behaviors, ideas or concepts shared by virtually all human cultures ) They use many different methods of study, but modern population genetics, participant observation and other techniques often take anthropologists " into the field ," which means traveling to a community in its own setting, to do something called " fieldwork.

There are two fundamental ways of modelling a Biological system ( e. g., living cell ) both coming under Bioinformatic approaches.

Biological weapons ( often termed " bio-weapons " or " bio-agents ") are living organisms or replicating entities ( viruses ) that reproduce or replicate within their host victims.

Though herbicides are chemicals, they are often grouped with biological warfare and chemical warfare because they may work in a similar manner as biotoxins or bioregulators and also because the Army Biological Laboratory tested them and the Army's Technical Escort Unit which all chemical, biological, radiological ( nuclear ) materials.

The other types of protected areas in Costa Rica are National Wildlife Refuges, Biological Reserves, Protection Zones, and Absolute Nature Reserves.

189 countries which are signatory to the Convention on Biological Diversity ( Rio Accord ) have committed to preparing a Biodiversity Action Plan, a first step at identifying specific endangered species and habitats, country by country.

Biological vectors are often responsible for serious blood-borne diseases, such as malaria, viral encephalitis, Chagas disease, Lyme disease and African sleeping sickness.

Biological vectors are usually, though not exclusively, arthropods, such as mosquitoes, ticks, fleas and lice.

Biological psychiatry follows a biomedical model where many mental disorders are conceptualized as disorders of brain circuits likely caused by developmental processes shaped by a complex interplay of genetics and experience.

Some incidents cited in A Higher Form of Killing: The Secret History of Chemical and Biological Warfare are as follows:

Indigenous peoples have argued, through various international forums such as the United Nations Permanent Forum on Indigenous Issues and the Convention on Biological Diversity, that there are four pillars of sustainable development, the fourth being cultural.

Biological taxonomy is a sub-discipline of biology, and is generally practiced by biologists known as " taxonomists ", though enthusiastic naturalists are also frequently involved in the publication of new taxa.

Biological classification is a critical step in the taxonomic process, as it informs the user as to what the relatives of the taxon are hypothesized to be.

UNCCD activities are coordinated with the secretariats of other relevant international bodies and conventions, like those of the UN Framework Convention on Climate Change ( UNFCCC ) and the Convention on Biological Diversity ( CBD ).

In Europe, the model organism resource centre for Arabidopsis thaliana germplasm, bioinformatics and molecular biology resources ( including GeneChips ) is the Nottingham Arabidopsis Stock Centre – NASC whilst in North America germplasm services are provided by the Arabidopsis Biological Resource Center, ( ABRC ) based at the Ohio State University.

Biological cells, given suitable environments, reproduce by cell division.

Biological valves are valves of animals, like pigs, which undergo several chemical procedures in order to make them suitable for implantation in the human heart.
