Question: What is not one of the roles of the parasympathetic nervous system?
a) increases digestive functions
b) maintains resting heart rate
c) stimulating urination
d) controls the diameter of blood vessels
Answer:
d) controls the diameter of blood vessels
Explanation:
The activated parasympathetic nervous system is mainly associated with the rest and digest activities. This division of the autonomic nervous system triggers the digestive glands to release their secretions and stimulate the contractions of smooth muscles of the digestive tract to upregulate the processes of digestion and absorption of nutrients. In this way, the parasympathetic nervous system restores and conserves the energy of the body. It has no effect on the diameter of blood vessels.
The sympathetic nervous system triggers constriction of blood vessels that supply blood to kidneys and digestive tract during emergency conditions. It also dilates the blood vessels that supply blood to skeletal muscles, cardiac muscles and liver to facilitate increased blood supply to these tissues.
Answer:
The best answer to the question: The Z disc forms the end____ of a sarcomere, would be: the end border, or the point where sarcomeres join, within a muscle fiber.
Explanation:
Concretely, a Z disc is the boundary line that divides sarcomeres within a muscle fiber. They are the bordes between sarcomeres and they contain the most important molecule, actin, which forms the thin filaments essential for muscle tissue movement. This actin molecule, present along the Z discs, under the correct stimulation and circumstances, will bind to myosin and thus movement will be possible.
I think this is False since I think earth can hold life since there’s gravity and many sources of food and water to have as well as shelter. Also there’s oxygen so we can breathe. And god brought us her. So yeha ♀️
The exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
you need to figure out the landscapes and where certain things grow. you should try to figure out what thrives in that environment
