Your sense of smell, taste and vision all involve chemical reactions, but your hearing system is based solely on physical movement. In this article, we'll look at the mechanical systems that make hearing possi
Describe two fundamental differences between chemical and electrical synapses. 1. Explain how graded potentials and action potentials are different. 2. On which part of a neuron would you expect a graded potential to occur? 3. On which part of a neuron would you expect an action poten...
They are invisible to our eyes. They bring music to our radios, sound and picture to our televisions, and carry signals to our cell phones. Cell phone waves are shorter than radio waves, but longer than microwaves. Microwaves: Also invisible, we use microwaves to heat our food quickly. ...
A neuron is nerve cell. Neurons are the basic building blocks of the nervous system. Neurons are highly specialized cells that transmit information throughout the body.Answer and Explanation: Neurons communicate with each other using action potentials and chemical neurotransmitters. The junction between...
The same goes for using retinol alongside exfoliating scrubs and chemical peels, which can cause the same type of reaction on the skin. Instead of putting too many actives onto the skin at once, take a less is more approach. Stick with gentle, hydrating products as your skin acclimates to...
these sensors are designed to interact with specific substances, such as NO₂ or CO₂, and convert these chemical interactions into electrical signals for real-time monitoring. These sensors play a crucial role in industrial settings, where exposure to harmful gases can have severe consequences ...
Phthalates.These are common across all kinds of cosmetic and skincare products, including deodorant and antiperspirants. It’s a chemical that allows other ingredients to be flexible and also extends the life of any added fragrances. Phthalates are concerning because they may disrupt yourendocrine sy...
and 2c on my crown. That's part of the fun of being a curly girl. All of us are in-between, and no two textures are alike. The diameter of the hair may be different, the density of the strands may vary, and the porosity and growth cycles of the strands will change.Everyone has...
What are the mediums for sound mechanical waves? How can mechanical energy can be converted to electrical energy? How can chemical energy be converted into electrical energy? How can energy exist before matter (the big bang theory) if energy comes from matter? Is it possible to create sound...
It is rather the most important ordering tool in the biological space between intracellular and extracellular activities, “… a window through which a unitary biological element can sense its chemical and electrical environment” [176]. And it is replete with microcurrent. The cell’s outer ...
