Answer:

Suprachiasmatic nucleus.

Explanation:

Suprachiasmatic nucleus may be defined as the small region present in the hypothalamus region of the brain. They are present or situated right above the optic chiasm.

They are also regulated by the chemical and the hormonal changes. The circadian rhythm is also influenced by the suprachiasmatic nucleus. These nucleus regulates the rhythm by the retinal proteins that are light sensitive and triggers the signal in the suprachiasmatic nucleus.

Thus, the answer is suprachiasmatic nucleus.

Answer:

The best answer to the question: You should suspect:___, would be, A: moderate dehydration.

Explanation:

This is a 6-month old baby who has been with diarrhea and vomiting for two days. He presents a lessened level of activity, a heart rate of 140 bpm and whose anterior fontanelle appears shrunken due to the loss of water and electrolytes. However, there are also good news: the baby has not had either emesis, or diarrheic episodes for at least 12 hours.

Taking these symptoms into consideration we can say that the child has moderate, and not severe dehydration, or even worse, hypovolemic shock, because his heart rate, which would be one of the most clear indications of severe dehydration, is still within the normal ranges for a child of that age (80 to 160 bpm for children between 2 and 11 months). Also, the child has reduced levels of activity, but there is still presence of activity and he is still concious. Finally, the fontanelle´s situation, although worrisome, is indicative that the volumes in the child are low, but can be brought back up easily enough since he has not presented another episode in 12 hours.

Plant cells produce hormones that affect plant growth and behavior. Cytokinins and auxins are two important types of plant hormo
goldfiish [28.3K]

Answer:

Plant hormones are among the most important biochemicals affecting plant growth and yield production under different conditions, including stress. Plant hormones include auxin, abscisic acid, ethylene, gibberellins, cytokinins, salicylic acid, strigolactones, brassinosteroids, and nitrous (nitric) oxide. Plant functioning under stress is affected by plant hormones, which can help the plant to tolerate the environmental stresses. A wide range of actions have been illustrated for plant hormones. If it is possible to regulate the activities of plant hormones under stress, the production of tolerant plant species will be more likely. Soybean [Glycine max (Merr.) L.] growth and activities, including the process of nodulation and biological N fixation with the N fixing bacteria Bradyrhizobium japonicum, are also regulated by plant hormones. The important point about plant hormones is their interactions and cross talk, affecting their activity and efficiency in plants under different conditions, including environmental stresses. Some of the most important findings related to the behavior of the soybean and its symbiotic B. japonicum under environmental stresses as affected by plant hormones are presented.
