Describe how the parasympathetic nervous system influences one function in your body. For example, the parasympathetic nervous system causes decreased blood pressure. If you chose this body function, you would describe the physiology behind the decreased blood pressure. How does it happen? What occurs in the heart/blood vessels? Which scenarios or external factors would cause the parasympathetic nervous system to activate this response?

The primary neurotransmitter is acetylcholine. Relax state of mind and body causes activation of parasympathetic nervous system.e

Explanation:

Parasympathetic nervous system conserves energy and is responsible for steady state activity giving a feeling of relaxationw. Parasympathetic nervous system acts as a control system. Functions of parasymapthetic nervous system are salivation, lacrimation, urination, digestion and defecation. It uses acetylcholine as neurotransmitter. It acts on muscarinic and nicotinic cholinergic receptors.

PNS opens (dilates) blood vessels leading to the gastrointestinal tract, aiding digestion. It stimulates salivary gland secretion and accelerates peristalsis , helping absorption of nutrients. It constricts the bronchioles of the lungs.

the father in the first generation probably had the recessive colorblind trait in his x chromosome. if he and his wife both had the colorblind trait, even if she had 1 recessive and 1 dominant, then that trait would be passed on to their kids.

(since you didn't attach the family tree this is just an assumption)

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
