Deamidation removes the amide functional group from asparagine and glutamine, they are changed into aspartic and glutamic acid.
Deamidation takes place when acid-catalyzed direct nucleophilic attack of water on the amide, the most common mechanism is considered as intramolecular cyclization that involves in nucleophilic attack by the succeeding amide nitrogen to form a succinimide intermediate
Optimizing pH is the best approach for stabilizing proteins against deamidation and isomerization. Deamidation reactions are base-catalyzed and increase between pH 5–8.

True or False. Movement of injested food through the digestive system is unidirectional in animals using alimentary canals and in animals using gastrovascular cavities.
Movement of ingested food through the digestive system is unidirectional in animals using alimentary canals and in animals using gastrovascular cavities is False.
It is bidirectional because it enters the oral cavity from the bottom and exits the same way it entered, back toward its original location. Mammals are unidirectional in nature.
The mouth is where ingested material enters and travels through a hollow, tubular cavity. The cells lining the gastrovascular cavity take in the food particles.
An animal with an alimentary canal is something like an earthworm. Following ingestion through the mouth, food travels through the esophagus and is stored in the crop before entering the gizzard to be churned and digested. The food enters the intestine from the gizzard, where nutrients are absorbed and waste is expelled as casts through the anus.

to diagnose cardiovascular problems, a technique known as angiography can be performed to visualize blood flow in the affected area. a catheter is inserted through the wall of a blood vessel and then threaded into the area of interest, where an x-ray contrast agent is released. the contrast agent is carried along with the flow of blood and is visible on the x-ray for a short distance (e.g. an inch) from the point of release. to visualize blood flow through the coronary arteries, what is an appropriate site to insert the catheter? keep in mind that catheters are much wider than capillaries! (choose all that apply.)
Contrast agents are injected into the blood during an angiography to enhance the visualization of blood flow.
This is beneficial for identifying and treating a variety of illnesses, particularly those that affect the heart and brain. The rationale behind angiography is covered in this article.
The angiography is used by your doctor to look for constricted or clogged blood arteries in your heart. X-ray imaging is used during a coronary angiography procedure to visualize the blood arteries in your heart. The test is typically performed to determine whether there is a limitation in the blood flow to the heart.
After that, an x-ray of the area is taken while a contrast dye is administered into the catheter. On the x-ray, the contrast makes the artery visible.

The identified bands on the sarcomere were shown to differ at various levels of muscle contraction and relaxation, leading to the development of the sliding filament theory of muscle contraction.
The binding of myosin to actin, which results in cross-bridges that cause filament movement, is the process of contraction.
The fibers in our muscles are what move our bodies. They also make it possible for our internal organs to function. According to experts, there are around 650 skeletal muscles in the human body. Muscles are specialized tissues with the ability to stretch, and each muscle has an infinite number of muscular fibers. Myofibrils are gradually smaller and thinner strands found in muscle fibers. Muscle contraction is necessary for movement. When tension-producing areas within the muscle fibers are stimulated, it contracts.
The sliding filament idea explains how this mechanism works. According to the sliding filament theory, actin and myosin filaments, which overlap each other during contraction of striated muscles, shorten the length of the muscle fibers. Cellular mobility is governed by actin (thin filaments) and myosin (thick filaments).

Behavior of dolphins:Dolphins use social cues that have been adjusted for the water, their bodies, and their sensory systems. Like anthropologists, human researchers observe these dolphins in the water in a nonthreatening way while interacting with them to build rapport and trust. Numerous specific dolphins have been identified for more than 20 years. In order to interact with this strange civilization, it has been crucial to learn the right cultural etiquette. The dolphins frequently start spontaneous displays, mimicking, imitation, and synchrony to interact with humans. These characteristics may arise as universal traits when one sentient species contacts another with the aim of starting a relationship. This should be taken into account for real-time communication. Complex alliance relationships in bottlenose dolphins and a look at the conditions that were most favorable for the emergence of large brain sizes in mammals are examples of the social intelligence of dolphins. The requirement to establish social techniques including the recognition of a large number of people and their relationships with one another is one example of potential cognitive demands. Males may exhibit more complicated patterns of alliance affiliation than is now understood for any non-human, with participants engaging in 2-3 layers of shifting alliances. Males use soft contact behaviors like petting to manage alliance connections, but synchronization is also crucial in affiliative interactions. In general, the degree to which there are strategic options and risk will determine the selection for social intelligence in the setting of shifting alliances.
