Ingratiating is a psychological technique in which an individual attempts to influence another person by becoming more likeable to their target. This term was coined by social psychologist Edward E. Jones , who further defined ingratiating as "a class of strategic behaviors illicitly designed to influence a particular other person concerning ...
Intracellular transport is unique to eukaryotic cells because they possess organelles enclosed in membranes that need to be mediated for exchange of cargo to take place. [3] Conversely, in prokaryotic cells, there is no need for this specialized transport mechanism because there are no membranous organelles and compartments to traffic between.
Direct contact between cells allows the receptors on one cell to bind the small molecules attached to the plasma membrane of different cell. In eukaryotes, many of the cells during early development communicate through direct contact. [5] Synaptic signaling, an integral part of nervous system activity, occurs between neurons and target cells.
One known example of this kind of memory is what happens to pancreatic cells when they are exposed to a large amount of sugar. In response, they release into the bloodstream a pulse of insulin, a ...
Active transport enables these cells to take up salts from this dilute solution against the direction of the concentration gradient. For example, chloride (Cl −) and nitrate (NO 3 −) ions exist in the cytosol of plant cells, and need to be transported into the vacuole. While the vacuole has channels for these ions, transportation of them is ...
Starvation response in animals (including humans) is a set of adaptive biochemical and physiological changes, triggered by lack of food or extreme weight loss, in which the body seeks to conserve energy by reducing metabolic rate and/or non-resting energy expenditure to prolong survival and preserve body fat and lean mass.
Cancer cells may become dependent on stress response mechanisms that involve lysosomal macromolecule degradation, or even autophagy that recycles entire organelles [12] However, tumor cells exhibit therapeutic stress resistance-associated secretory phenotype involving extracellular vesicles (EVs) such as oncosomes and heat shock proteins.

Most of the processes animated were the result of Alain Viel and Robert Lue's work describing the processes to the team. Alain Viel is an associate director of undergraduate research at Harvard University. The film took 14 months to create for 8.5 minutes of animation. It was first seen by a wide audience at the 2006 SIGGRAPH conference in Boston.
