What is the meaning of tolerance in biology?

Tolerance is the: 1. ability of an organism to endure unfavourable environmental conditions; 2. amount of a chemical in food considered safe for humans or animals.

What is tolerance in biology and examples?

An organism’s capacity to survive variation in environmental conditions. An organisms tolerance to a given factor will influence its distribution. For instance we often assume plants need light, when in reality they have a higher tolerance to light. Too much light can be even more damaging than too little.

What are tolerance limits biology?

Tolerance limits consist of the the upper and lower limits of a particular environmental condition which allows a certain species to survive. Creatures that have a greater range of tolerance can survive in a larger area and are more widely distributed.

What does ecological tolerance mean?

Ecological Tolerance. the range of abiotic conditions in which a species can survive. Range. The range of environmental conditions that are tolerable for survival in a species. Too little or too much of a specific environmental condition may result in death.

What is tolerance example?

Tolerance is being patient, understanding and accepting of anything different. An example of tolerance is Muslims, Christians and Athiests being friends. (uncountable) The ability of the body (other organism) to resist the action of a poison, to cope with a dangerous drug or to survive infection by an organism.

What is tolerance in pharmacology?

Tolerance is a person’s diminished response to a drug, which occurs when the drug is used repeatedly and the body adapts to the continued presence of the drug.

What is a species tolerance?

A small mutualistic community. We quantify a species’ tolerance as the change in strength of mutualistic interaction that species can sustain before becoming extinct. Figure 1: Pollinator tolerance depends on the direction of change in the strength of mutualistic interaction.

What does acclimation mean in biology?

acclimatization, any of the numerous gradual, long-term responses of an organism to changes in its environment. Such responses are more or less habitual and reversible should environmental conditions revert to an earlier state.

What is tolerance answer in one line?

Solution. Tolerance is respecting the opinions of others which are different from our own opinion.

What is tolerance Short answer?

Definition of tolerance 1 : capacity to endure pain or hardship : endurance, fortitude, stamina. 2a : sympathy or indulgence for beliefs or practices differing from or conflicting with one’s own. b : the act of allowing something : toleration.

What is pharmacodynamic tolerance?

Pharmacodynamic tolerance occurs when the intrinsic responsivity of the receptor system diminishes over time. Acute tolerance is mediated predominantly by pharmacodynamic mechanisms, manifested as a decreased response following a single administration of the agent or during repeat-dosing but over a short time frame.

What is profile tolerance?

Profile tolerance is the amount of deviation of a profile of a line or a surface. No surface can be made absolutely perfect. Due to machine or measurement variations, engineers should allow a deviation in the line elements or surfaces called profile tolerance. Please make a note that, Profile tolerance can be used with or without a datum.

What is the difference between GD and profile tolerance?

GD Profile of a Line Definition. In GD, profile of a line tolerance is similar in many respects to profile tolerance. The major difference is that profile of a line establishes a two-dimensional tolerance zone that controls individual line elements of a feature or surface.

What is the tolerance zone of a line?

So, the tolerance zone is two parallel lines to the ideal line of the feature, separated by the tolerance. The actual line must fall entirely between the two lines making up the tolerance zone. Profile of a Line is seldom used for simple features as there are simpler ways to tolerance a radius or a simple straight line.

What is the difference between profile tolerance zone and datum?

When used without a datum, it just controls the shape of the line or surface. When profile tolerance is used with datums, it can control the form, size, orientation and position of the surface. The virtual envelope that gets created by the profile tolerances is called the profile tolerance zone.
