Long DNA helices with a high GC-content have more strongly interacting strands, while short helices with high AT content have more weakly interacting strands. [28] In biology, parts of the DNA double helix that need to separate easily, such as the TATAAT Pribnow box in some promoters , tend to have a high AT content, making the strands easier ...
By the most general biophysiological definition, the biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, cryosphere, hydrosphere, and atmosphere.
Nutritional science (also nutrition science, sometimes short nutrition, dated trophology [1]) is the science that studies the physiological process of nutrition (primarily human nutrition), interpreting the nutrients and other substances in food in relation to maintenance, growth, reproduction, health and disease of an organism.

Predation is a short-term interaction, in which the predator, here an osprey, kills and eats its prey. Short-term interactions, including predation and pollination, are extremely important in ecology and evolution. These are short-lived in terms of the duration of a single interaction: a predator kills and eats a prey; a pollinator transfers ...
Conservation biology is the study of the conservation of nature and of Earth's biodiversity with the aim of protecting species, their habitats, ...
Parts of a typical chromosome: (1) Chromatid (2) Centromere (3) Short (p) arm (4) Long (q) arm. In genetics, a locus (pl.: loci) is a specific, fixed position on a chromosome where a particular gene or genetic marker is located. [1]
In biology, a substrate is the surface on which an organism (such as a plant, fungus, or animal) lives.A substrate can include biotic or abiotic materials and animals. For example, encrusting algae that lives on a rock (its substrate) can be itself a substrate for an animal that lives on top of the algae.
Great egret and neotropic cormorant competing over territory. Competition is an interaction between organisms or species in which both require a resource that is in limited supply (such as food, water, or territory). [1]
