Answer:
Convergent Evolution
Explanation:
Convergent evolution occurs when two unrelated species that have no common ancestor evolve independently in order to adapt to a similar environmental constraints to ensure survival.
An example of convergent evolution can be seen in birds, bats, flight/wing insects. They all do not share a common ancestor, but have evolved, separately, a similar structure for flight.
Another example can be seen in dolphins and sharks. These two different species share similar physical characteristics that make them adapt well in marine habitat that helps them to predate

A. Hormones act as signal molecules between all body systems
Peripheral Chemoreceptors (Carotid + Aortic Bodies) and Central Chemoreceptors in the Medulla Oblongata detect high Carbon Dioxide levels in the blood during exercise. The respiratory centre in the Medulla Oblongata + PONS stimulate the intercostal muscles and the diphragm to contract in order to increase the rate and depth of breathing as to decrease levels of Carbon dioxide in the blood.
The thyroid gland secretes thyroxine which speeds up metabolism (the rate at which cells use glucose)
This part of the brain is called CEREBELLUM.
The cerebellum is the part of the brain that receives information from the sensory system, the spinal cord and other parts of the brain and then regulate motor movements, such as posture, balance, speech and coordination. <span />
