Answer:
The Caenorhabditis elegans dauer state is a hibernation-like state of diapause that displays a dramatic reduction in spontaneous locomotion.
Explanation:
Mutations affecting the neurotransmitter dopamine, which regulates voluntary movement in many organisms, can stimulate movement in dauers. The movement of quiescent animals is stimulated by conditions that reduce dopamine signaling and also by conditions predicted to increase dopamine signaling.The stimulation of movement by increased dopamine is much more pronounced in quiescent daf-2(−) dauer and dauer-like adult animals.
In C. elegans hermaphrodites, dopamine is produced by eight neurons and signals via at least four dopamine receptors, DOP-1 through DOP-4. In addition, a presynaptic reuptake transporter, DAT-1, removes dopamine from the extracellular space to terminate signaling. In C. elegans, dopamine is best known for mediating the “basal slowing response” in which the animal's movement slows when it encounters food.. Dopamine is thought to be released in response to food and to act on motor neurons to modulate the animal's movement . Animals that cannot produce dopamine fail to slow in response to food and exogenous dopamine slows the movement of animals cultured without food.The response to dopamine in this situation is complex, as the absence of specific dopamine receptors can have either positive or negative effects on movement.
Yes. the stomata has small openings found at the bottom of the leaves
Answer:
C
Explanation:
Ecological relationships exist between organisms in an ecosystem. MUTUALISM is one of these ecological relationships in which both organisms involved benefits from the relationship. It usually occurs in a way that the actions of one favors the other.
In this example, the bees feed on nectar produced by the flower a plant and carries pollen along when it feeds on the nectar produced by the flower of another plant. The bees are getting fed, thanks to the plant, while the plant is getting cross-pollinated, thanks to the bee.
Answer:
The Marburg virus wasn't mutating this early on, therefore the Coronavirus is much more deadlier and almost impossible to get a cure for, due to the rapid change in pathogens!
The enzyme that breaks down H2O2 is called catalase.
