Why do bubbles pop when touched by something hot?
Bubbles pop when touched by something hot because the heat causes the water inside the bubble to evaporate rapidly, weakening the surface tension of the bubble. This leads to the bubble bursting and the water vaporizing into the air.
What typically feel slippery when touched?
Substances like oil, soap, lotion, ice, and wet surfaces such as water or ice can feel slippery when touched. This slipperiness is caused by reduced friction between the surface and the skin, making it difficult to maintain a firm grip.
What is the definition of a smooth surface?
In general, we can say a surface is smooth if it's lack of any "grip" or textural features presents no friction.
What is corneal reflex somatic?
The corneal reflex is a protective reflex involving the sensory branch of the trigeminal nerve (V) and the motor branch of the facial nerve (VII). When the cornea is touched, nerve impulses trigger a blinking reflex to protect the eye from potential damage.
How do you describe the texture of a brick?
A brick typically has a rough and coarse texture due to its coarse surface and grainy feel. It is solid and dense, with a slightly gritty feel when touched.
When the tentacle of a hydra is touched the entire organism responds because?
The nerve net carries impulses in more than one direction.
What is topical anesthesia?
condition of temporary numbness caused by applying a substance directly to a surface of the body. Loss of feeling occurs in the specific areas touched by the anesthetic substance.
How many people have touched the moon?
Twelve astronauts have walked on the moon, all of whom have touched its surface.
What do you call water that has not touched the ground?
Its called as surface water.
What is tropical anesthesia?
Topical anesthesia is a condition of temporary numbness caused by applying a substance directly to a surface of the body. Loss of feeling occurs in the specific areas touched by the anesthetic substance.
What phobia is the fear of having your armpits touched?
that would come under Aphenphosmphobia - the fear of being touched
How something feels or looks like it would feel if touched?
Texture refers to the tactile sensation of a surface when touched. It describes how something feels, such as rough, smooth, bumpy, soft, or slippery. Visual texture, on the other hand, refers to the appearance of a surface that suggests how it would feel if touched.
When young Johnyy touched a hot surface and withdraw his hand?
Dont play with fire...
Why nervous coordination so fast?
the Nervous system's coordination is so fast mainly because the human body has thousands or even million of nerves cells that are connected to one another. every action that happen in our body is transmitted to the brain. what runs in our nerve cells are called electric impulses the speed of electric impulses is just a split seconds. example: when you accidentally touched a hot object the reflex of our body is to let go of it. because the nerves cells already send electric impulses to our brain that the thing we touched is hot. then the brain will send another electric impulses to our hands that says let go of it its hot. this process happens within split seconds only.
How are nerv impulses transmitted?
Nerve impulses are transmitted between neurons, into neurons, and along neurons. They are transmitted between neurons at a synapse, into neurons at a dendrite, and along neurons at the axon.Transmission at the synapse is via neurotransmitters released from the end of one neuron into the synapse, where they diffuse quickly over to the next neuron, usually to a dendrite or dendritic spine.Transmission into the next neuron is by the neurotransmitters causing pores to open in the next neuron which allow Sodium ions to enter, which begin to propagate a electrochemical impulse by electrotonic conduction along a dendrite and across the soma. Electrotonic conduction is a process in which ions "bump" one another, causing them to somewhat "pile up" eventually at the axon hillock at the beginning of the axon. It's a very fast process, but it looses strength along the way, so in order for the axon to fire, there needs to be either many dendrites contributing, or one or more dendrites being stimulated quickly and often, so as to allow a summation of the voltages resulting from the "pile up" of the ions at the axon hillock.Transmission along the axon of the neuron is by the action potential, which involves a successive exchange of Sodium and Potassium ions, each exchange causing the next.for more about the action potential, see:How_does_a_nerve_impulse_get_transmitted_along_an_axonoriginal answer:Nerve Impulses are transmitted electrochemically via an action potential.Information (either a sensation such as being touched, or a desire for action such as moving your hand and picking up a pen) is passed from the nerves dendrites to its axon which stimulates the action potential.The action potential is a whole subject in itself.

How does messages go to your brain?
Messages are sent to your brain through your nervous system. Nerve cells called neurons transmit signals through electrical and chemical processes. When a stimulus is detected by sensory receptors, such as touch or sound, nerve impulses are generated and travel through the nervous system to the brain for interpretation.
