What is a primary response?
(The response that the immune system displays when first exposed to an antigen.) (medical-dictionary.thefreedictionary.com/primary+response)
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
Is the tendency of iron to form rust when exposed to air is it chemical or physical property?
It is a chemical property.
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.

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.
What chemical will burn when exposed to the sun?
chemical
If an organism grows in the OF-glucose medium that is exposed to air is the organism osidative or fermentaive?
The organism will be Oxidative because it is exposed to the air, fermentation will occur in an anaerobic enviornment, meaning in the absence of oxygen.

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.
