Regulation of heart rate, blood pressure, and digestive functions are carried out by the <u>autonomic nervous system</u>

What is autonomic nervous system?
The peripheral nervous system's autonomic nervous system (ANS), originally known as the vegetative nervous system (VNS), provides smooth muscle and glands, which in turn affects how internal organs work. The autonomic nervous system is a control system that regulates body processes like the heart rate, digestion, respiratory rate, pupillary response, and urination mainly subconsciously. The fundamental mechanism in charge of the fight-or-flight response is this system.
Through the brainstem, the spinal cord, and the organs, integrated reflexes control the autonomic nervous system. Control of respiration, cardiac regulation (the cardiac control center), vasomotor activity (the vasomotor center), and other reflex acts including coughing, sneezing, swallowing, and vomiting are all examples of autonomic functions.

The correct answer is D. Pioneer species
Explanation:
In biology, the term "pioneer species" refer to the first species that colonize new environments or environments in which there is no biodiversity for example lands that have been affected by fire, lava, etc. These species are in most cases plants or small organism that are resistant and able to adapt to the harsh conditions of new land. Additionally, this concept differs from keystone and foundation species because these two concepts describe species that have an important role in the ecosystem rather than those that first live on new land. Therefore, the first species to live on new land are the pioneer species.
