biological child
Any child conceived rather than adopted by a specified parent, and therefore, carrying genes from the parent.
biological clock
1. An internal time-measuring mechanism which helps to adjust an organism's daily activities, seasonal activities, or both in response to environmental cues.
2. The internal mechanism of an organism that regulates circadian rhythms (daily cycles of activities) observed in many living organisms and various other periodic cycles.

The mechanism of the biological clock has long proved elusive; however, a molecular basis for such a clock in the fruit fly Drosophila has been discovered, and similar mechanisms may well apply in other organisms.

It is based on the cyclical rise and fall in the concentrations of certain proteins which form part of a negative feedback loop that controls transcription of their own genes.

biological community
All of the organisms inhabiting a given area.
biological concentration
biological control
The use of natural predators or parasites, instead of chemicals, to control pests.

The most famous successful example was the introduction of the gray moth, Cactoblastis cactorum, into Australia to control the prickly pear, Opuntia inermis, which was over running vast tracts of land. The moth's caterpillars eat the shoots of the plant.

Another example is the introduction of parasitic wasps that lay their eggs inside the eggs of pest insects; such as, corn borers that attack corn (maize).

Populations of insect pests may also be reduced by releasing sterile males to mate with the females, or by using sex-attractant chemicals (pheromones) to trap males or females.

biological dose (s) (noun), biological doses (pl)
The amount of radiation absorbed in biological material: The scientist developed a way to measure the biological dose of the radiation treatment of the lump on the patient’s foot.
biological dosimetry (s) (noun) (usually only singular)
An area of science that uses the physical damage produced by radiation to estimate radiation doses: It was small comfort for the patient to know that the tissue damage sustained from the radiation was considered important for biological dosimetry.
biological effective dose; abbreviated, BED (s) (noun), biological effective doses (pl)
The amount of a substance that is sufficient to bring about some significant physiological changes in the affected organism; specifically, the level of exposure to a toxic substance that is required to produce a harmful effect: The doctors continue to study the biological effective doses of radiation that are being administered to treat the skin cancer of Mark's cousin.

biological half-life

biological parent, birth parent
A parent who has conceived (biological mother) or sired (biological father) rather than adopted a child and whose genes are therefore transmitted to the child.
biological plausibility
When a causal association (or relationship between two factors) is consistent with existing medical knowledge.
