____is associated with deamination of protein
Answer:
Deamination is the removal of an amino group from a molecule
Deamination is associated with deamination of protein
Answer:
in humans , deamination takes place primarily in the liver, it can also occur in the kidney. if there's excess protein intake , deamination is used to break down proteins with amino acids for energyWhen you centrifuge the DNA isolated from the bacteria, the DNA separates into two classes. One class of labeled DNA includes very large molecules (thousands or even millions of nucleotides long), and the other includes short stretches of DNA (several hundred to a few thousand nucleotides in length). Which two classes of DNA do these different samples represent
Answer:
Leading strand and Okazaki fragments
Explanation:
The two classes of DNA that the different samples represent include the leading strand and the Okazaki fragments.
The large molecules DNA with thousands/millions of nucleotides constitutes the leading strand of the DNA while the short stretches of DNA with just a few thousand nucleotides in light constitute the Okazaki fragments.
This is because, during replication, the leading strands of DNAs are usually synthesized in a continuous manner and end up forming a long, continuous daughter strand while the lagging strands are usually synthesized in short, discontinuous fragments known as the Okazaki fragments.
The continuous/discontinuous replication of the leading/lagging strands of the DNA is due to the characteristics of the enzyme responsible for adding bases to the growing daughter strands. The DNA polymerase enzyme can only add nucleotides in the 5' to ' direction.

Answer:
The goal of disinfection of public water supplies is the elimination of the pathogens that are responsible for waterborne diseases. The transmission of diseases such as typhoid and paratyphoid fevers, cholera, salmonellosis, and shigellosis can be controlled with treatments that substantially reduce the total number of viable microorganisms in the water.
While the concentration of organisms in drinking water after effective disinfection may be exceedingly small, sterilization (i.e., killing all the microbes present) is not attempted. Sterilization is not only impractical, it cannot be maintained in the distribution system. Assessment of the reduction in microbes that is sufficient to protect against the transmission of pathogens in water is discussed below.
Chlorination is the most widely used method for disinfecting water supplies in the United States. The near universal adoption of this method can be attributed to its convenience and to its highly satisfactory performance as a disinfectant, which has been established by decades of use. It has been so successful that freedom from epidemics of waterborne diseases is now virtually taken for granted. As stated in Drinking Water and Health (National Academy of Sciences, 1977), "chlorination is the standard of disinfection against which others are compared."
However, the discovery that chlorination can result in the formation of trihalomethanes (THM's) and other halogenated hydrocarbons has prompted the reexamination of available disinfection methodology to determine alternative agents or procedures (Morris, 1975).
The method of choice for disinfecting water for human consumption depends on a variety of factors (Symons et al., 1977). These include:
its efficacy against waterborne pathogens (bacteria, viruses, protozoa, and helminths);
the accuracy with which the process can be monitored and controlled;
its ability to produce a residual that provides an added measure of protection against possible posttreatment contamination resulting from faults in the distribution system;
the aesthetic quality of the treated water; and
the availability of the technology for the adoption of the method on the scale that is required for public water supplies.
Economic factors will also play a part in the final decision; however, this study is confined to a discussion of the five factors listed above as they apply to various disinfectants.
The propensity of various disinfection methods to produce by-products having effects on health (other than those relating to the control of infectious diseases) and the possibility of eliminating or avoiding these undesirable by-products are also important factors to be weighed when making the final decisions about overall suitability of methods to disinfect drinking water. The subcommittee has not attempted to deal with these problems since the chemistry of disinfectants in water and the toxicology of expected by-products have been studied by other subcommittees of the Safe Drinking Water Committee, whose reports appear in Chapter III of this volume (Chemistry) and Chapter IV (Toxicity) of Drinking Water and Health, Vol. 3.
Organization of the Study
The general considerations noted in the immediately following material should be borne in mind when considering each method of disinfection. Available information on the obvious major candidates for drinking water disinfection—chlorine, ozone, chlorine dioxide, iodine, and bromine—is then evaluated for each method individually in the following sections. Other less obvious possibilities are also examined to see if they have been overlooked unjustly in previous studies or if it might be profitable to conduct further experimentation on them. Disinfection by chloramines is dealt with in parallel with that effected by chlorine because of the close relationship the former has to chlorine disinfection under conditions that might normally be encountered in drinking water treatment.

Imagine an invertebrate that lives in an estuary where salinity varies cyclically with the tides. If this individual is able to adjust the salt concentration of its body fluids, its salt concentration will have:____. a. a cyclic variation depending upon when the animal drinks. b. regular variations that range from large to small. c. slight fluctuations that are kept within a narrow range. d. a cyclic variation opposite that of the surrounding water.
Answer: Option C.
slight fluctuations that are kept within a narrow range.
Explanation:
An invertebrate that lives in an estuary where salinity varies cyclically with the tides. If this individual is able to adjust the salt concentration of its body fluids, its salt concentration will have slight fluctuations that are kept within a narrow range so has to maintain homeostasis and prevent the cells of the the invertebrate from not shrinking which can be due to the salt solution (Hypertonic).
Estuary is an area of water or shorelines where river meet the ocean. It normal do have concentration of salts. Organisms that live in estuaries must be able to adapt to their dynamic environments, wich is due to variations in water chemistry includes salinity, as well as physical changes like the rise and fall of tides.
How are surface waves different from body waves? Which are more damaging?
Answer:
Explanation:
surface waves decay more slowly with distance than body waves, which travel in three dimensions. Particle motion of surface waves is larger than that of body waves, so surface waves tend to cause more damage.
Answer:
surface waves decay more slowly with distance than body waves, which travel in three dimensions. The particle motion of surface waves is larger than that of body waves, so surface waves tend to cause more damage. Surface waves. Their side-to-side motion (like a snake wriggling) causes the ground to twist from side to side, that's why Love waves cause the most damage to structures. Rayleigh waves create a rolling, up, and down motion with an elliptical and retrograde particle motion confined to the vertical plane in the direction of propagation.

What are emergent properties?
Answer:
Emerging properties may arise by transient interactions such as individual organisms building a population. Human interaction in populations leads to the emergence of language, poetry, musical composition, and art. When populations of different species interact, communities form. Many emergent properties are the result of interactions between species in communities.
Emergent properties are characteristics of a system that do not exist in any of its constituent parts individually but originate as a result of interactions between those parts.
What does the characters indicate at ?These characteristics are frequently intricate and challenging to forecast. Emergent characteristics are a crucial idea in several disciplines, including physics, chemistry, and biology.
Emergent qualities in biology can be observed in an organism's behaviour. For instance, a flock of birds' behaviour is an emergent characteristic of the individual birds that make up the flock.
The behaviour of the flock is a product of interactions among the individual birds and is not exhibited by any one individual bird. Similar to this, a school of fish's behaviour is an emergent characteristic of each fish.
Emergent features in chemistry can be observed in how molecules behave. An emergent attribute of a substance's individual molecules, for instance, is the substance's boiling point. The boiling point is not a property of any one molecule, but rather the outcome of interactions between the molecules.
Particle behaviour in physics exhibits emergent features. An emergent attribute of a material's individual particles, for instance, is the material's electrical conductivity.
The interactions between the individual particles produce the electrical conductivity, which is not a property of any one of the individual particles. As a result, emergent properties are characteristics of a system that develop.

Explanation:
In part A, you analyzed genes that contribute to two diseases. (cystic fibrosis and muscular dystrophy) How can scientists use this information to develop new treatments for these diseases? Based on your findings, do you think that scientists will need to develop multiple treatments to control symptoms of these diseases? Explain your reasoning.
Answer:
By designing suitable gene therapies in order to restore target gene expression.
Explanation:
Cystic fibrosis and muscular dystrophy are inherited genetic disorders associated with serious health problems. Cystic fibrosis is caused by mutations in the gene that encodes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein, and it is a condition associated with abnormal production of sticky mucus that leads to problems in the lungs and the digestive systems. On the other hand, muscular dystrophy is produced by mutations in genes localized on the X chromosome such as, for example, the gene 'dystrophin'. Gene therapy is an experimental approach used to compensate abnormal gene function by introducing exogenous genetic material and thus restore their altered protein products. Consequently, personalized gene therapies can be useful to treat inherited disorders such as cystic fibrosis and muscular dystrophy.
