* 1972 – Seventy-four nations sign the Biological Weapons Convention, the first multilateral disarmament treaty banning the production of biological weapons.

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

Offensive biological warfare, including mass production, stockpiling and use of biological weapons, was outlawed by the 1972 Biological Weapons Convention ( BWC ).

Biological weapons allow for the potential to create a level of destruction and loss of life far in excess of nuclear, chemical or conventional weapons, relative to their mass and cost of development and storage.

Biological weapons also target fisheries as well as water-based vegetation.

This type of warfare is distinct from Nuclear warfare and Biological warfare, which together make up NBC, the military acronym for Nuclear, Biological, and Chemical ( warfare or weapons ), all of which are considered " weapons of mass destruction " ( WMD ).

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.

Biological factors which may be related to the development of a heterosexual, homosexual, bisexual or asexual orientation include genes, prenatal hormones, and brain structure.

Biological females may undergo vaginectomy, while males may undergo penectomy.

* Biological fatherthe natural father, or procreator of a child, who may or may not take part in the child's up-bringing.

Biological SSSIs may be selected for various reasons, governed by published SSSI Selection Guidelines.

Biological factors that may influence gender identity include pre-and post-natal hormone levels and gene regulation.

Biological toxicity can be difficult to measure because the " threshold dose " may be a single organism.

Biological methods have also been proposed to control whitefly infestation, and may be paired with chemical methods.

Biological processes are employed in the treatment of wastewater and these processes may include, for example, aerated lagoons, activated sludge or slow sand filters.

Biological reasons for gender variances in flashbulb memory may be explained by amygdala asymmetry.

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

Biological clock may refer to:

2001 Biological Sciences ) that Macroscincus coctei was most closely related to the Mabuya genus of the Scincidae and may have constituted a clade.

The Barbary Falcon is one of the rare cases that may arguably be considered a species under the Biological, but certainly not under the Phylogenetic Species Concept rather than the other way around as usual.

Biological hazards may stem from the potential for legionella exposure at work or the investigation of biological injury or effects at work, such as dermatitis may be investigated.

Biological dispersal may be contrasted with geodispersal, which is the mixing of previously isolated populations ( or whole biotas ) following the erosion of geographic barriers to dispersal or gene flow ( Lieberman, 2005 ; Albert and Reis, 2011 ).

Biological psychiatry and other approaches to mental illness are not mutually exclusive, but may simply attempt to deal with the phenomena at different levels of explanation.

The AMX-10RC is equipped with an NBC ( Nuclear / Biological / Chemical ) protection system and may conduct reconnaissance in a radioactive environment.

Biological warfare is considered to be primarily a strategic weapon.

The late author Sheldon H. Harris in his book " Factories of Death: Japanese Biological Warfare, 1932-1945, and the American cover up " wrote that, The test program, could be part of Project AGILE or Project OCONUS which began in fall 1962 and which was funded at least through fiscal year 1963, was considered by the Chemical Corps to be “ an ambitious one .” The tests were designed to cover “ not only trials at sea, but Arctic and tropical environmental tests as well .” The tests, presumably, were conducted at what research officers designated, but did not name, “ satellite sites .” These sites were located both in the continental United States and in foreign countries.

Biological specimens typically require to be chemically fixed, dehydrated and embedded in a polymer resin to stabilize them sufficiently to allow ultrathin sectioning.

Biological tissue must be supported in a hard matrix to allow sufficiently thin sections to be cut, typically 5 μm ( micrometres ; 1000 micrometres

Critics, including the Center of Biological Diversity and New Mexico Department of Game and Fish, were concerned the jaguar was being sacrificed for the government's new border fence, which is to be built along many of the cat's typical crossings between the United States and Mexico.

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.

Seed and DNA stocks can be obtained from NASC or the Arabidopsis Biological Resource Center.

To be admitted, a state must: be a producer / exporter of arms or sensitive industrial equipment ; maintain non-proliferation policies and appropriate national policies including: adherence to non-proliferation policies, control list and, where applicable, guidelines of the Nuclear Suppliers Group, the Missile Technology Control Regime and the Australia Group ; and adherence to the Nuclear Non-Proliferation Treaty, the Biological Weapons Convention, the Chemical Weapons Convention and, where applicable, START I, including the Lisbon Protocol ; and maintain fully effective export controls.

* Biological agent, infectious disease or toxin that can be used in bioterrorism or biological warfare

It also hosts the National Cancer Institute-Frederick ( NCI-Frederick ) and will be home to the National Interagency Confederation for Biological Research ( NICBR )

The aquarium was built in honor of the work of Edward Ricketts ( 1897-1948 ), a marine biologist who specialized in describing communities of organisms ( which would also be the focus of aquarium tanks ), and whose old laboratory ( Pacific Biological Laboratories ) and home resides next to the present MBA site.

Biological control might be a new possible way to control Staphylococcus aureus in body surfaces.

John Dupre, in a number of papers, but mainly in his paper " Natural Kinds and Biological Taxa " has demonstrated that the theory of natural kinds, which many have taken to be established and / or supported by Putnam's Twin-Earth Thought experiment does not find support in the practice of scientific classification.

Two environmental conservation areas can be found in this city: " Delta do Jacuí " ( Jacuí Delta ) State Park and Lami Biological Reserve.
