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.

Answer:
The process of phosphorylating ADP to form ATP and removing a phosphate from ATP to form ADP in order to store and release energy respectively is known as the ATP cycle.

Biodiversity decreases, and the overall health of the ecosystem decreases.
Answer: Option D
<u>Explanation:</u>
In a niche when two different species occupy a niche competition arises between them. In due course both the species fight for existence and nature selects the best adaptable one to win. The other species either reduces in its population or gradually in struggle for existence they deteriorate and die.
Hence a decrease in bio diversity happens here due to natural selection. If the biodiversity is decreased in a particular niche it affects the growth of different species which in turn affect the whole ecosystem resulting in decrease of the overall health in an ecosystem.
Answer:
Yeast-two-hybrid technique is one of the most important molecular technique that can be used to study the interactions at the molecular level. The interactions between the protein and DNA-protein interaction can be studied by this technique.
If the individual wants to study the liver liver-specific receptor protein then yeast-two-hybrid technique can be applied. The interested protein that can acts as prey and bait proteins must be covalently linked with the other third protein known as the reporter protein. Then the activity of the reporter protein is studied with the interactions of the prey and bait protein.
