How is the opeaning and closing of stomach regulated?
The opening and closing of the stomach is regulated by the pylorus. The pylorus is a part of the gastrointestinal tract, that prevents digested food from entering back into the stomach from the small intestines.
What is the primary feature of a neuron that prevents the action potential from traveling back from where it just passed?
Antidromic conduction, or the process of an action potential traveling backwards, is possible. However, regardless of the direction of the action potential, it is propagated by voltage-gated ion channels. Whenever these channels open, there is a sudden exchange of ions, after which the channels snap shut. During this period, known as the refractory period, the channels will not reopen, and thus an action potential will not be able to reverse direction.
What is the function of the waxy transparent top of layer of leaves?
The waxy transparent layer of leaves prevents water evaporation.
What is the function of a capsule in bacteria that makes it phatogenic?
It prevents phagocytosis of the bacteria and also provides mechanical protection from harmful agents and prevents drying up.
When Chemical weathering happens more slowly in desert areas due to a lack of?
Lack of rain prevents chemical erosion in a dessert.
How would a chemical that prevents the opening of voltage-regulated Na channels affect the function of a neuron?
Blocking voltage-regulated Na channels would prevent the influx of sodium ions, which are essential for generating action potentials in neurons. This would impair the neuron's ability to propagate electrical signals and communicate with other neurons. Overall, it would lead to a decrease in neuronal activity and disruption of normal nerve function.
Is a stabiliser a chemical?
A stabilizer prevents a chemical reaction.

What chemical prevents clotting in the circulatory system?
Heparin
What is the chemical that prevents the growth of unwanted plants?
herbicides
What is the function of tunica albuginea?
prevents penetration injuries
Effects of lidocaine on nerves?
it prevents sodium channels from opening which removes a neuron's resting membrane potential

What makes a material an insulator?
It's chemical structure that prevents movement of electrons.
What is the protective function of the mucus?
it somehow prevents foreign materials to get through the body.
