Why is ''botox'' an effective anti-wrinkle treatment.describe its mechanism of action with reference to the neuromuscular junction?

"Botox" is actually a poison. It prevents muscle movement by preventing the nerve impulse to travel from the neuron across the neuromuscular junction and prevents the muscle from contracting.
It is the toxin produced by the microbe that causes botulism.

What are the functions of physiological dead space?
There is no function of the physiological dead space. It is inevitable to be there in this design of respiration. So it is the defect in the design. But you have a very large physiological reserve to overcome the defect in this design. You have very effective system as in case of fish to get the oxygen out of water. But there is very low oxygen contents in water, making it essential to have such effective mechanism. Such effective mechanism is not necessary when abundant oxygen is available in air.
What is the underlying mechanism of a laminar flow hood in microbiology?
The underlying mechanism of a laminar flow hood in any application, including microbiology is that a roughly non-turbulent flow of air is more effective at preventing cross contamination of materials in the hood and having that air go through a high efficiency filter first is effective in preventing contamination by microbes and other items from outside the hood.

Mechanism of action of neostigmine?
There are 3 different types of acetylcholinesterase inhibitors - short-acting, medium-duration and irreversible inhibitors, which differ in their interactions with the active site of acetylcholinesterase.=Neostigmine is a medium-duration acetylcholinesterase inhibitor that enhances cholinergic transmission in the central nervous system, autonomic nervous system and at neuromuscular junctions. Acetlycholinesterase inhibitors are an established therapy for Alzheimer's disease and dementia .=
What is the transport mechanism using ATP?

Discuss whether the price mechanism is an effective way to solve the basic economic problem?
Price mechanism is an effective way to solve the basic economic problem. The price of a product is what will determine the demand and this will influence the production output which directly affects the economy.
Is the price mechanism an effective way to the solve the basic economic problem?
The price mechanism is a feature of the free market and operates through demand and supply and the self interest of individuals, government action is minimised. This has the benefits of incentive, efficiency, innovation, choice and consumer sovereignty. Against this there may be market failure including inequality, lack of public and merit goods, externalities and instability. Depending upon the degree of failure the mechanism may be more or less effective. The price mechanism does not solve the basic economic problem but is thought to be effective when operating efficiently.
Why do skunks give out bad smells?
The musky smell is a defense mechanism, which is an effective repellent against many predators.

Explain the importance of effective consultative mechanisma in managing health and safety risks and describe what they entail?
Effective consultative mechanism is important because it is important in making policies to manage health and safety risks.
What causes muscular fatigue after just a few minutes of intense exertion?
Reduction in the effectiveness of a muscle or muscle group reflected by a decline in peak tension. Local muscular fatigue may be due to one or more reasons, such as failure of a motor nerve to transmit nerve impulses to the muscle; fatigue at the neuromuscular junction through depletion of neurotransmitters; inability of the contractile mechanism (the actin and myosin myofilaments) to generate force; accumulation of protons from lactic acid in the muscle; depletion of ATP and phosphocreatine; or failure of the central nervous system to initiate and relay nerve impulses to the muscle. The most probable sites of local muscular fatigue are the neuromuscular junctions, the contractile mechanism of the muscle itself, and the central nervous system. Fatigue at the neuromuscular junction, which might be more common in fast twitch fibres, is probably due to depletion of http://www.answers.com/topic/acetylcholine. Fatigue within the contractile mechanism may be caused by accumulation of protons, depletion of ATP and phosphocreatine; depletion of muscle glycogen; dehydration; or lack of oxygen and inadequate blood flow.

In addition to the hearts performance as an effective pumping mechanism what two factors must be balanced from proper circulation?
blood volume and vascular capacity providing resistance
The Back hatch latch will not open?
The back hatch will often not open if the internal mechanism or release has become damaged. Replacing the latch is the most effective and reliable fix.
What is unusual about the modern concert harp?
It is tuned as a diatonic instrument, but it has an elaborate mechanism to independently change the effective lengths of the strings so that it can play all the notes of the chromatic scale.
What is difference between process and mechanism?
process is process and mechanism is mechanism.
