Phototaxis is a behavioral response exhibited by certain organisms in which they move towards or away from a source of light. This movement is often seen in simple organisms like bacteria, algae, and insects as a way to navigate their environment or seek out resources.
Phototaxis is the behavior in which animals move toward (positive phototaxis) or away from (negative phototaxis) a light source. This behavior is commonly observed in various organisms, such as insects, plants, and microorganisms, as they respond to light stimuli for navigation, finding food, or avoiding predators.
positive phototaxis.
Paramecium can respond to light by moving towards or away from it through a process called phototaxis. When exposed to light, Paramecium will swim towards the light source (positive phototaxis) or swim away from it (negative phototaxis) depending on the species and environmental conditions.
Dugesia will exibit negative phototaxis. Look it up in a zoology book. here is an article as well. http://www.helium.com/items/1079086-the-observation-of-dugesia-in-response-to-light-and-gravity
They can. Some ants engage in symbiotic relationships with some plants on occasion. For the common ant and your average garden flower, ants should not have a positive or negative effect.
Positive + Negative = Negative Negative + Negative = Positive Positive + Positive = Positive Negative + Positive = Negative
Negative * positive = negative Positive * positive = positive Negative * negative = positive
Insects that use phototaxis are moths and cockroaches. Phototaxis means that these insects are attracted to light and will move towards it.
Phototaxis is the oriented movement of a cell or organism in response to light, while chemotaxis is the movement towards or away from a chemical stimulus. These responses help organisms navigate towards beneficial conditions or resources in their environment.
The rules for the sign (positive or negative) of the result of a multiplication is the same as division. For multiplication: Positive * Positive --> Positive Positive * Negative --> Negative Negative * Positive --> Negative Negative * Negative --> Positive For division: Positive / Positive --> Positive Positive / Negative --> Negative Negative / Positive --> Negative Negative / Negative --> Positive
