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.

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 largest and most inclusive biological level among cells, tissues, organs, and organ systems is organ systems. Organ systems are made up of organs that work together to perform specific functions in the body, such as the digestive system or the circulatory system.
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.
the four biological systems are fisheries,forests, grasslands, cropland. It is depleted because of over fishing, forest disappear for firewood, grassland and converted into barren wasteland and cropland deteriorate. Their productivity is badly affected as they are reaching now an unsustainable level. so the life support in earth os being depleted fast.
ACCORDIND TO NAVNEET'S VIEW POINT IT SHOULD BE ! the four biological systems are fisheries,forests, grasslands, cropland. It is depleted because of over fishing, forest disappear for firewood, grassland and converted into barren wasteland and cropland deteriorate. Their productivity is badly affected as they are reaching now an unsustainable level. so the life support in earth os being depleted fast.
The earth's principal biological systems include the ecosystems, biodiversity, and food webs. These systems are interconnected and work together to support life on our planet by regulating important processes such as nutrient cycling, energy flow, and the stability of ecosystems.
Journal of Biological Systems was created in 1993.
ATP is stable in biological systems.
Yes, aspartic acid can be phosphorylated in biological systems.
In biological systems, phosphates typically carry a charge of -3.
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.
Yes, aspartate can be phosphorylated in biological systems through the addition of a phosphate group to its structure.
In biological systems, active transport moves substances against the concentration gradient.
