The majority of the accessible drinking water on our planet comes from glaciers.
NADPH, or nicotinamide adenine dinucleotide phosphate, is essential for photosynthetic organism carbohydrates. This reduced coenzyme is a high energy molecule and a reduced form of NADP+ that plays a key role in driving the Calvin cycle.
To predict the Ph values of the solutions I thought about what I knew about each solution. Battery acid and stomach acid have the words acid in them, so I knew they would be on the acidic side of the scale. yeah
Answer:
D.H
Explanation:
The glass of water which is asked in the question is made up of sodium silicate thus we can know that which ions are present in a glass of water.
From the glass itself we will get oxygen ion which is from sodium silicate and from the water present in the glass we will get the water breaking into H+ and hydroxyl ions.
Answer:
The correct answer is ''loss of acetylcholine receptors in the end-plate membrane.''
Explanation:
Myasthenia gravis represents a human autoimmune disease. The neuromuscular junction abnormalities that occur in this disease are due to antibody-mediated processes. A reduction in the number of functional acetylcholine receptors on the postsynaptic membrane was established to contribute to the physiological abnormalities of myasthenia gravis. The reduction in receptors is due to immunological alterations directed against the acetylcholine receptor. Normally, when acetylcholine binds to its receptor, it opens allowing the rapid entry of cations, especially sodium. With this, the depolarization of the postsynaptic region of the muscle fiber occurs. Although acetylcholine is normally released in myasthenia gravis, it is not capable of causing an action potential in the muscle sufficient to initiate or weaken contraction. In patients with myasthenia gravis, failure to activate muscles is responsible for myasthenic fatigue. Most patients have elevated serum titers of antireceptor antibodies, which in turn accelerate receptor degradation.
