Answer:
b. Works within an upper and lower range
c. " Is regulatory. "
d. Is very common in biological systems
Explanation:
Negative feedback is the regulatory mechanism that maintains homeostasis by counteracting the deviation. Any change serves as a stimulus and a response is produced to reverse the change. Negative feedback is a very common regulatory mechanism to maintain internal body conditions within a narrow range.
For example, the body temperature in adults is maintained within the narrow range of around 36 -37 degrees Celsius. An increase or decrease in the body temperature from the set point is counteracted to restore the set point. An increase in body temperature is reversed by the vasodilation of blood capillaries of skin layers to lose the heat to the surroundings. On the other hand, reduced body temperature below the set point is restored by constriction of capillaries of skin layers.
Answer:
The answer is B. Eumetazoa and Lophotrochozoa.
Explanation:
The difference between the lophotrochozoa and deuterostomia is the way they develop on the cigote phase.
Lophotrochozoa are a clase that has a spyral shape.
The literature mentions that the phylum Cycliophora are coelomates and their embryos undergo spyral cleavage which is a common characteristic of the Lophotrochozoa.
The Eumetazoa clase are conformed on organisms whit his own tissues and the phylum Cycliophora has a "U-shaped intestine that brings it´s sanus close to the mouth".
In conclusion, the correct answer is that the phylum Cycliophora gets into the clases Eumetazoa and Lophotrochozoa.
