What's the difference between a dynamic site and a static one?
Static Web pages often look the same, and rarely change the text. You must create the page yourself or request a Web designer to make a change for you. You must then upload the newly created page and any images to the Web servers.The same is true of interactive websites. They can change each time they’re loaded (without someone having to make those changes), and they can also change their content depending on what visitors to your website do. You may create the dynamic page to respond to information entered by visitors to your site. They usually store and pull information from a database that underlies it.When you do not want to change things yourself with a Web page editor, dynamic sites will reduce the ongoing maintenance costs. Typically they cost more to build, because they require more complex coding. There's also a need to build a content management tool to help you manage your site. Most consumers within their sites have a mix of dynamic and static components. For example, they can use dynamic pages for a catalog of goods where they need to alter details or images periodically. The pages of "Chat" and "About Us" are mostly left in static shape.
What is the difference between the key and lock theory and the induced fit model?
The key and lock theory suggests that enzymes and substrates fit together like a key fits into a lock with a rigid, non-flexible active site. In contrast, the induced fit model proposes that the enzyme's active site can change its shape to accommodate the substrate, thus providing a more dynamic interaction between the enzyme and substrate.
What is lock and key fit?
It's a model used to describe one specific object fitting into another specific receptor; such as using a key on a lock that's how it gets its name. This is used to describe many things mainly cells and their receptors
What was the name of atomic bomb test site?
The atomic bomb test site was named the Trinity Test Site. It was located in New Mexico, USA, and was where the first atomic bomb was successfully detonated on July 16, 1945.
Is Trinity Site the location of the first atomic bomb testing?
Yes, Trinity Site is the location of the first atomic bomb testing. It was the site of the Trinity Test, which was the first detonation of a nuclear weapon on July 16, 1945, as part of the Manhattan Project.
What happens to the neurotransmitters that fail to attach to a receptor site?
In a process called reuptake, they are reabsorbed by sending the neuron and recycled.

Is the theory that a drug attaches itself to speacialized cells the receptor site theory?
Receptor Site Theory
The site in the neuron where EPSPs and IPSPs are integrated is the?
The Axon Hillcock is the site where EPSPs AND IPSPs are integrated in the neuron.
How the neuron allow impulse transmission?
A neuron is able to conduct electrical signals and/or neural impulses by means of the movement of electrically charged ions along and into and out of sections of the neuron.A neural signal is initiated in a neuron as neurotransmitter chemicals are released by another neuron into a small space near the neuron. As the neurotransmitters diffuse across the gap (called a synapse), they move into receptor sites on the post-synaptic neuron. The receptors are cave-like hollows or pits which are part of ligand-gated sodium ion pores, which also have a tunnel part which can be opened or closed. The tunnel part, the pore, is normally closed, but when the neurotransmitter fits into the receptor site, its presence causes the tunnel ( the pore) to open, and allow sodium ions into the post-synaptic neuron.As the electrically charged ions enter the neuron, they repel one another away from the entry point, in a process called electrotonic conduction, moving down the dendrite and along the surface of the soma (body of the neuron), until they pile up at the beginning of the axon, at the axon hillock. This movement of ions amount to an electrical current.At the axon hillock, if the voltage manifested by the piled up ions is high enough, it will cause voltage-gated sodium ion pores to open in the initial segment of the axon, allowing more electrically charged sodium ions in, which opens more nearby v-gated Na ion pores, which lets more sodium ions in, and this process continues down the axon in a process called an action potential, which simply means a 'moving' or 'active' voltage (potential), which constitutes an electrical signal, specifically an impulse (because at any point along the axon the membrane voltage rises suddenly to a peak value, and then falls back to the resting membrane voltage).The result of all of this is that a voltage has moved along the neuron, as an electric signal.
What site where the motor neuron and muscle cell meet is called the?
The site where a motor neuron and muscle cell meet is called the neuromuscular junction. This is where the motor neuron releases neurotransmitters that signal the muscle cell to contract.
Can agonists or antagonists that mimic neurotransmitters be mistakenly stored in terminal buttons during reuptake?
Some neurotransmitter molecules have a molecular structure that precisely fits the receptor site on the receiving neuron, much as a key fits a lock. When the agonist molecule excites, it is similar enough in structure to the neurotransmitter molecule that it mimics its effects on the receiving neuron. Morphine, for instance, mimics the action of endorphins by stimulating receptors in brain areas involved in mood and pain sensations. This antagonist molecule inhibits. It has a structure similar enough to the neurotransmitter to occupy its receptor site and block its action, but not similar enough to stimulate the receptor.
Which molecule covers the binding site?
Proteins can cover the binding site of a receptor and prevent another molecule from binding to it. This interaction can inhibit the receptor's activity and affect cellular signaling pathways.
The same receptor can have different effects depending on the properties of the?
ligand that binds to it. For example, a receptor can trigger different signaling pathways or cellular responses if it binds to different ligands, even if they bind to the same binding site on the receptor. This is known as ligand-dependent receptor activation.
What does the process of transmitting a nerve impulse from one neuron to another involve?
When a neurotransmitter lands on their receptor site, they can either excite of inhibit the receiving cell. To excite a cell, positive sodium ions flow to it, which depolarizes the membrane in a similar way to a nerve impulse. The depolarizing effect spreads through the membrane and only last for 1/3 of a millisecond.
Can Chemical transmitters stimulate any receptor site to initiate an action?
No, chemical transmitters can only stimulate specific receptor sites that they are designed to bind to. Each transmitter has a specific shape that fits into a corresponding receptor site like a lock and key, triggering a specific response in the target cell. This specificity is essential for precise communication between cells in the body.
What is a binding site?
The binding site is where a specific binding molecule and a specific receptor protein can combine. This combination can only occur at the binding site. All in the 9th grade text book
