Answer:
a. VIP (vasoactive intestinal peptide)
Explanation:
The enteric nervous system (ENS) is one of the main divisions of the autonomic nervous system (ANS) together with sympathetic and parasympathetic nervous system. This system consists of neurons that regulate the function of the gastrointestinal tract (GI).
Inhibitory interneurons that are part of the enteric nervous system also known as Dogiel type I neurones achieve their inhibitory transmission via nitric oxide, adenosine triphosphate, vasoactive intestinal peptide (VIP) and pituitary activating cyclic AMP. They usually act directly on smooth muscles of GI.
The olfactory epithelium is a specialized epithelial tissue inside the nasal cavity that is involved in smell. In humans, it lies on the roof of the nasal cavity about 7 cm above and behind the nostrils.
the lightest radiation is Aron.
a chemical substance produced and released into the environment by an animal, especially a mammal or an insect, affecting the behavior or physiology of others of its species.
Answer: c) Some organisms rely on energy captured from inorganic compounds to drive basic biological processes.
Explanation:
Deep-sea hydrothermal vents are hot spots of geothermal water. The organisms living in deep-sea vents cannot obtain energy from sunlight. They are dependent on chemosynthesis, which involves the utilization of inorganic substances to produce organic substances, which allows their survival and act as a source of energy. In the given situation, bacteria present on the surface of mussels are capable of chemosynthesis also the mussels are dependent upon inorganic hydrogen in seawater. Thus chemosynthesis supports the survival of organisms living in the deep sea vents.
