A. Multiple organ systems working together
Explanation:
All of the organ systems work together to maintain homeostasis in humans because each system does something different. For example, the circulatory system delivers oxygen rich blood to the bones and the bones create new blood cells. When one thing is wrong with one system, it affects all of the systems, like a disease. Another example of this would be the central nervous systems and endocrine working together to coordinate messages to the brain about the body's state while resting and exercising to maintain homeostasis.
Answer:
All of the choices are correct.
Explanation:
- When a substance emits light which is not a result of heat, then such a spontaneous emission fo light is known as luminescence.
- Several chemical reactions or electrical energy can lead to the production of luminescence by organisms.
- The enzyme that is responsible for the production of bioluminescence by the organism is luciferase and it is capable of producing luminescence by catalyzing oxido-reductive processes.
- Luminescence is also produced in bacteria, and it is often controlled by the process of quorum sensing.
The maximum volume of air breathed in during the period of rest for each minute is 500 ml also known as tidal volume.
Tidal volume is simply each breath a person takes. It is a significant factor in both minute and alveolar ventilation. The quantity of air that enters the lungs each minute is measured by minute ventilation also referred to as total ventilation. It is a function of both tidal volume and respiratory rate.
A physiological term called tidal volume (Vt or TV) is used to indicate how much air is generally moved during inspiration and expiration when you are at rest. Spirometry, a non-invasive test, is used to measure it. Adults breathe on average seven milliliters (mL) every kilogram (kg) of ideal body weight.
When it comes to configuring the ventilator in critically ill patients, tidal volume is crucial. Delivering a tidal volume that is both large enough to sustain proper breathing and small enough to prevent lung trauma is the objective.
