The levels of organization of biological systems from simplest to most complex are: atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystems, and biosphere.
The primary purpose of biological warfare agents is to cause harm or death to humans, animals, or plants during warfare. These agents are designed to incapacitate or kill enemies by using biological toxins or infectious organisms.

Halides are found in biological systems - most organisms have tons of dissolved chloride ion, and mammals at least have quite a bit of dissolved iodide.Are you asking why biological systems don't have HALOGENS? ?Halides are ions (like chloride, aka Cl-) and halogens are the molecular forms (like chlorine, aka Cl2). ?Halogens and acid anhydrides are toxic to biological systems because they are very reactive, and would halogenate and form adducts on proteins, DNA, etc. ?They are also very reactive and would not exist long in the aqueous environment of a biological system.But fun fact: an enzyme in your thyroid gland (i think called thyroid perioxidase) makes transient amounts of iodine (I2) from iodide (I-) in the synthesis of thyroid hormone. ?But these are very small amounts localized to the thyroid gland, and only transiently.
Buffers are necessary in biological systems because it resist rapid changes in pH when acids and bases are added to it. Every living cell contains natural buffer systems to maintain the constant pH needed for cell function.
The levels of organization of biological systems from simplest to most complex are: atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystems, and biosphere.
Journal of Biological Systems was created in 1993.
ATP is stable in biological systems.
biological is a product used to induce immunity to various infectious deseases or noxious subtances of biological origin.
The series of terms in the sequence of biological organization from the simplest to the most complex is cell, tissues, organs, systems, and lastly the organism. This is the way living things are organized.
Yes, aspartic acid can be phosphorylated in biological systems.
In biological systems, phosphates typically carry a charge of -3.
the transfer of infectious diseases
A pathogen or infectious agent is a biological agent that causes disease or illness to its host.
In biological systems, amino acids such as serine, threonine, and tyrosine can be phosphorylated.
Yes, protein folding increases entropy in biological systems.
Crystal violet binds to nucleic acids, specifically DNA, in biological systems.
