Answer:
This can be achieved by increasing the resolution of the objective lens of the microscope. To achieve this both the objective lens ( with the dirt)and the specimen are immerse in the oil. The type of objective lens used for the immersion is called optical immersion objective
The oil is first applied to the specimen mounted on the microscope stage.Thus by raising the stage to torch objective lens both the lens and the specimen are immerse in oil. The oil Increases the resolution of the objective lens.
Generally the high refractive indices of the oil and water is close. Therefore the oil increase angular range at which the incident light on the lens will be transmitted , and therefore. focus on the specimen. Thus the oil with the objective lens reduces the refraction of light so that as light incident on the specimen the high refractive index of the lens and oil reduces the diffraction of light, and therefore focusing on the specimen increase.
Consequently, by adjusting the focal length , the objective lens at high magnification is able to resolve the dirt on it and the spots on the specimen. That is distinguished between the dirt on it and spots on the specimen as two distinct images rather than one.
Depends on what you consider "Large". Usually what we consider large amounts, would just make us urinate as it is not water that we need and so would filter it out.
However if you were to say ingest such an amount that it has become toxic, you run the risk of a very dangerous condition called Hyperhydration or Water Intoxication. Under most normal circumstances water and salt are present in cells and the blood. If you remember; water travels through osmosis, or from a higher to lower concentration across a semipermeable membrane. Salt helps to maintain the concentration. However if you drink so much water that it would be considered "toxic" the water that would eventually find it's way into your blood would try to balance with the cells, which begin to absorb so much water that they swell, therefore causing swelling to the body's tissues and organs.
The dangerous bit is when the brain begins to swell. Symptoms such as <span>headache, personality changes, changes in behavior, confusion, irritability, and drowsiness. These are sometimes followed by difficulty breathing during exertion, muscle weakness & pain, twitching, or cramping, nausea, vomiting, and thirst, begin to manifest. The dangerous bit is when the swelling compresses the brain to such a degree it crushes the brain stem and herniates through the foramen magnum. The brain stem or Medulla Oblangata is responsible for the processes keeping you alive, and if it's crushed your heart rate, blood pressure, and breathing will become compromised, a recognizable feature we EMT's look out for called Cushing's Triad. This is mostly irreversible and will lead to neurogenic shock, coma, and then death.
The important lesson, is to always take thing in moderation.</span>
Answer:
The true statement is <em>Hydrophobic side chains are usually in the interior of the native structure</em>.
Explanation:
In the native structure of a protein, the hydrophobic side chains of aminoacids- such as leucine (Leu), alanine (Ala), methionine (Met), and others-are located in the interior of the structure. They are buried inside the structure, whereas polar side chains are exposed to the outside in the structure, and they interact with water molecules.
Regarding the other statements, entropy-as a measure of disorder of a system-is very important in protein stability as we know that native conformations are more ordered systems, with lower entropy and higher stability. Aminoacids in the protein structure interact each other through Van der Waals interactions and hydrogen bonds.
