Chemical weapons are devices that use chemicals to inflict death or injury; biological weapons use pathogens or organisms that cause disease. Pathogens include bacteria, viruses, fungi, and toxins (poisons produced by animals or plants).

Chemical biology is one field that exists in the overlap between biology and chemistry. ... They study the chemical reactions that happen inside organisms and the molecular make up of compounds found in organisms. Chemical biology on the other hand involves stimulating biological systems using chemicals.

The primary difference that lies between these organic compounds and inorganic compounds is that organic compounds always have a carbon atom while most of the inorganic compounds do not contain the carbon atom in them. Almost all the organic compounds contain the carbon-hydrogen or a simple C-H bond in them.

What is the difference between a biological variable and a psychological variable? As variables, the psychological has no material substance, but the biological is based on material substances. people differ in terms of stable individual differences like needs and traits.

The term disease causative agent usually refers to the biological pathogen that causes a disease, such as a virus, parasite, fungus, or bacterium. Technically, the term can also refer to a toxin or toxic chemical that causes illness.

Organic matter is found in living, or once-living, organisms, so it is biological in nature. Inorganic matter is generally obtained from non-living matter, so it is mineral in nature. Inorganic compounds are less complex than organic compounds. The presence of carbon prevents organic compounds from forming salts.

Communicable agent is capable of entering and growing or reproducing within the body of the host, while pathogenic agent is the cause of the disease or health problem.

Microorganisms are controlled by means of physical agents and chemical agents. Physical agents include such methods of control as high or low temperature, desiccation, osmotic pressure, radiation, and filtration.

The biological sciences study the structure of the body, the body organs and their functioning. Psychology studies behavior. The behavior of an individual has a very close relationship with the body.

Acids are caustic chemical compounds that corrode substances by attacking them chemically, and that denature proteins and break down other biological compounds directly, causing physical damage which leads to bodily harm. Poisons are a broad definition of substances that are biologically hazardous.

A pathogen or infectious agent is a biological agent that causes disease or illness to its host. The term is most often used for agents that disrupt the normal physiology of a multicellular animal or plant. However, pathogens can infect unicellular organisms from all of the biological kingdoms.

biological science. ... Physical science is the science concerned with the study of inanimate natural objects, including physics, chemistry, astronomy, and related subjects. And biological science is the study of life and living organisms, their life cycles, adaptations and environment.

The key difference between organic acid and inorganic acid is that organic acids essentially contain carbon-hydrogen bonds in their structure whereas inorganic acids may or may not contain carbon. Generally, organic acids are weaker acids than inorganic acids.

Biochemistry is a pure science field, while biotechnology is an applied science field. ... Biochemistry deals with the process and pathways happening inside the living cell, while biotechnology deals with the techniques to study those processes, and applications of those processes.

A chemical is a single substance, for which we can measure and record physical and chemical properties. For example, benzene, or sulfuric acid. Individual chemicals may be used as a reagent, but also as solvent or catalyst. A reagent takes part in a chemical reaction, and is converted to something else.

What is the difference between organic and inorganic molecules? Organic molecules contain carbon and hydrogen, tend to be larger, have covalent bonds, and are non-electrolytes. Inorganic molecules consist of any substance that can't be classified as organic.

Biochemists study enzyme mediated chemical reactions in living things. They aim to unravel the chemistry of life. ... They aim to unravel the chemistry of life. In contrast Organic Chemists are interested in the chemistry of carbon compounds in general whether or not the chemical reactions of study occur in living systems.
