A surfactant is a chemical that disrupts hydrophilic/hydrophobic interactions, letting normally hydrophobic things dissolve in water (this is how soap cleans grease!). If I have a bunch of enzymes dissolved in water and I add a surfactant, what will happen to the enzyme structure
Answers
Explanation:
A good surfactant is going to have a hydrophilic head and a long hydrophobic tail. As a result, a surfactant molecule contains both an insoluble water (or an oil-soluble component) and a water-soluble component. Surfactant molecules will migrate to the surface of the water, where the insoluble hydrophobic group may extend out of the bulk phase of the water, either into the air or, if the water is mixed with oil, into the oil Phase, while the water-soluble head group remains in the water phase. This alignment and aggregation of surfactant molecules at the surface is intended to alter the surface properties of water at the water / air or water / oil interface.

Toxoplasma gondii is a protozoan parasite that causes toxoplasmosis, a generally mild but potentially fatal disease, especially in cats and human fetuses. Cats and other felines are considered their ultimate hosts because the sexed phase of their life cycle takes place there, making these animals the primary hosts of the parasite. The asexual phase of the life cycle can occur in any warm-blooded animal, such as other mammals and birds. Therefore, toxoplasmosis is a parasitic zoonosis.
Parasites invade the cells, forming a compartment called the parasitophore vacuole which form cysts in tissues, especially in the muscles and brain. Because the parasite is inside the cells, the host immune system does not detect these cysts. Antibiotic resistance varies, but cysts are difficult to eradicate entirely. Therefore, T. gondii spreads within these vacuoles through a series of binary divisions until the infested cell eventually breaks free.
Some people have flu-like signs and symptoms, which may be:
Swollen lymph nodesHeadacheFeverFatigueWidespread painIn people with impaired immune systems, symptoms may also include:
ConfusionLack of coordinationConvulsionsBlurred vision caused by intense swelling of the retinaIn recent years, several investigations indicate that the parasite can cause changes in the behavior associated with impulsivity, and personality disorders. So, we could predict it zombifies the host by changes in the behavior, because of the damage caused by a parasite in the brain. It is important to consider that the brain governs the body, and cysts found there can trigger these changes.

The following is a list of the steps that occur in the production of an auditory sensation. 1. The pressure wave distorts the basilar membrane on its way to the round window. 2. Movement of the tympanic membrane causes displacement of the malleus. 3. Displacement of the stereocilia stimulates sensory neurons of the cochlear nerve. 4. Movement of the malleus causes movement of the incus and stapes. 5. Distortion of the basilar membrane forces the hair cells of the organ of Corti toward or away from the tectorial membrane. 6. Movement of the oval window establishes pressure waves in the perilymph of the vestibular duct. The proper sequence for these steps is:___________.A. 2,4,1,6,5,3B. 2,4,6,3,5,1 C. 2,1,4,6,5,3D. 2,4,6,1,5,3E. 2,5,4,6,1,3
Answers
Answer:
The correct answer is option D, that is, 2,4,6,1,5,3.
Explanation:
With the approaching of sound waves, ear pinna mediates it towards the external auditory canal, this makes sound waves to reach the tympanic membrane. This results in the vibration of the tympanic membrane, and as the malleus, that is, the first ear ossicle, which is attached to the tympanic membrane gets displaced.
This movement of the malleus further moves the stapes and the incus. As the footplate of the stapes is associated with the oval window, the movement of the oval window takes place. This movement of the oval window creates pressure waves in the vestibular duct's perilymph. The movement of these pressure waves takes place from the Oval window to the Round window.
At the time of this movement, the pressure wave distorts the basilar membrane on its path to the round window, resulting in the vibration of the basilar membrane and the hair cells situated in the membrane against the tectorial membrane.
The stimulation of the sensory neurons takes place in the vestibulocochlear nerve's cochlear branch due to the displacement of the stereocilia. Post this, information reaches the auditory cortex in the temporal lobe's superior temporal gyrus, and hearing takes place.
Option D is the one that shows the correct sequence of steps in an auditory sensation. In this case, the sequence is 2,4,6,1,5 and 3.
We can arrive at this answer because:
At the beginning of auditory sensation, the pinna turns to the external acoustic meatus, directing the sound waves to the tympanic membrane.These waves provoke an intense vibration in the tipanic membrane, which provokes the displacement of the malleus.The displacement of the malleus causes a movement that also displaces the stapes, the incus, and the oval window.The movement of the oval window causes other waves that press against the round window.This causes the basilar membrane and hair cells to vibrate, causing stimulation of sensory neurons.At that point, auditory information reaches the auditory cortex in the temporal lobe, allowing hearing to take place.

Which of the following descries a solution that contain a buffer? A. Sodium hydroxide, a base, is added to the solution, and the pH of the solution becomes higher. B. Citric acid is added to the solution, but the pH of the solution does not change. C. Acetic acid is added to the solution, and the pH of the solution becomes lower. D. Distilled water is added to the solution, and the pH of the solution does not change.
Answers
Answer:
B. Citric acid is added to the solution, but the pH of the solution does not change.
Explanation:
In chemistry, buffer solutions or simply called Buffer are solutions that resist a change in pH when an acid or base is added to them i.e they maintain a constant pH. This is as a result of the content of the solution. A buffer may contain a weak acid and its conjugate base (salt) or a weak base and its conjugate acid.
Hence, when a strong base or acid is added to them, they still restore the original pH of the solution due to the reaction that removes or neutralizes the hydrogen or hydroxide ions from the acid and base added to them respectively. This is what happens when Citric acid is added to the solution, but the pH of the solution does not change.
Citric acid, which is an acid, does not practically increase or decrease the pH of the solution. Hence, the solution is called a buffer.
Answer:
Citric acid is added to the solution, but the pH of the solution does not change.
