Will an organism always have the same response to a chemical regardless of the dose it is exposed to?
No, an organism will not always have the same response to a chemical regardless of the dose. The response can vary significantly depending on the concentration of the chemical, as lower doses may elicit a different biological effect compared to higher doses. This phenomenon is often described by dose-response relationships, where the effects can range from no observable effect at low doses to toxic or harmful effects at high doses. Additionally, individual factors such as genetics, age, and health can influence an organism's response to a chemical.

Will an organism always have the same responde to a chemicsl regardless of the does it is exposed to?
No, an organism's response to a chemical can vary significantly depending on the dose it is exposed to. Low doses may elicit a different physiological or behavioral response compared to high doses, potentially leading to effects like hormesis, where a low dose has a beneficial effect, while a high dose may be toxic. Additionally, individual factors such as genetics, age, and health status can influence how an organism reacts to a chemical at any given dose.
Is copper turning green when exposed to the environment a chemical change?
Chemical because it is being exposed to another compound and forming a new substance
If you have just learned that a chemical you work with is a mutagen What effect does this chemical have?
A mutagen is a substance that can change the genetic material (DNA) of an organism, increasing the frequency of mutations. This can lead to potential harmful effects such as an increased risk of cancer or other genetic disorders in both the exposed individual and their offspring.
What would most likely happen to a unicellular organism if it was exposed to a hypotonic solution for an extended period of time?
The organism would swell and then burst.
Is the tendency of iron to form rust when exposed to air is it chemical or physical property?
It is a chemical property.

What is the procedure for lc50?
The relationship between the degree of response of the organism and the quantity of the chemical always assumes a classic concentration-response form. the graphs represent the results of the tests in which groups of the organisms of the same species were exposed to various concentrations of a chemical for a specific length of time.
What does mechanosensitive mean?
Mechanosensitivity is the specific response done by certain organisms when exposed to mechanical activity. These responses can be positive or negative in nature, depending on the organism.
If an organism grows in an OF-glucose medium that is exposed to air is the organism oxidative or fermentative?
Oxidative
If you're exposed to liquid chemical?
Depends on what the chemical is.
Is a type of chemical when exposed to radiation emits visible light?
is a type of chemical when exposed to radiation emits visible light.
If an organism grows in the OF-glucose medium that is exposed to air is the organism osidative or fermentaive?
If the organism grows in the OF-glucose medium exposed to air, it is likely undergoing oxidative metabolism. This is because air contains oxygen, which the organism can use through oxidative phosphorylation to generate energy. If the organism were fermentative, it would generate energy through fermentation pathways even in the presence of oxygen.
Is copper turning green when exposed to the environment a chemical change?
Chemical because it is being exposed to another compound and forming a new substance
In classical conditioning the learner is?
In classical conditioning, the learner is typically an organism (such as an animal or human) that is exposed to a conditioned stimulus paired with an unconditioned stimulus. The learner's behavior changes as a result of this pairing, leading to the formation of a conditioned response.

What is the difference between photo tactic and chemo tactic stimulus?
Taxis is an organism's instinctive movement either towards or away from a stimulant. Positive taxis occurs when an organism moves up a gradient, towards a stimulus. Negative taxis occurs when an organism moves down a gradient, away from a stimulus.Phototaxis occurs when an organism moves either towards or away from a light source. (That is, up or down a light gradient). The phototactic stimulus is the light itself (regardless of whether the organism moves towards or away from it).For example, a single-celled Euglena (a photosynthetic protist) exhibits positive phototaxis during the daytime: when exposed to sun, it moves from dim areas up the light gradient into bright sunshine. The phototactic stimulus is sunlight.Chemotaxis occurs when an organism moves either towards or away from a chemical source. (That is, up or down a chemical gradient). Thus the chemotactic stimulus is the source of the chemical (again, regardless of whether the organism moves towards or away from it).Interestingly, positive chemotaxis facilitates the process of fertilization in mammals. The egg secretes powerful chemical attractants, which the sperm swim towards enthusiastically as they make their way up the fallopian tube, like a hungry traveler following his nose to a bakery. For the sperm, the chemotactic stimulus is the chemical attractant secreted by the egg.
