Carbon Cycle

Explanation:

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.

Answer:

It is called EXCRETION.

Explanation:

This is a process by which metabolic waste is removed from a living organism.

The excretory organs removes these waste.

Accumulation of these in the body is very harmful to our system.

Hope all these helps.

Answer:

The adenosine triphosphate (ATP) molecule

Explanation:

The actin filaments are often associated with myosin to produce muscle contraction. These myosin filaments are considered to be 'molecular motors' capable of converting the chemical energy contained in the ATP molecule to mechanical energy, thereby producing cell movement. Myosin heads bind to actin filaments in order to generate a power stroke. When the adenosine triphosphate (ATP) molecule binds to myosin, the myosin head detaches to the actin filament. During this process, the ATP molecule is broken down and then the released energy is used by the myosin filament to return to its original position.

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.

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.

Deamination is associated with deamination of protein​

Answer:

Answer:

Nitrogen is mobile while phosphorus is immobile in the soil.

Explanation:

Nitrogen fertilizers are those fertilizers which provide nitrogen to the plants that is required by plants for the formation of amino acids. It increases vegetative growth of plant. Nitrogen fertilizer is highly mobile due to soluble in water and contaminated the underground water by leaching while phosphorus fertilizer are those fertilizer which provide second macro-nutrient i. e. phosphorus to the plants. Phosphorus is a vital component of energy molecule such as ATP. It is insoluble in water so it is immobile. Only 20 % of the applied phosphorus fertilizer is available to plants.

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:

b. dilation of the afferent arterioles and inhibition of renin release.

Explanation:

Atrial Natiuretic Peptide is a hormone which is mainly made and secreted in the atria. It helps in the regulation of blood pressure levels with the use of the kidney through an increase in water and sodium excretion.

The hormone helps in the regulation of blood pressure by ensuring there are dilation of the afferent arterioles to give room for increased flow of blood due to the increased pressure. Study also shows that the enzyme inhibits the release of renin.

Answer:

Due to mixing of particles present in the upper layer of limestone with sandstone during deposition.

Explanation:

The parent layer was limestone layer which is older than sandstone layer. This sandstone layer spreads on the limestone layer because of wind. The wind moves these sandstone from other region and their deposition occurs on the limestone layer. During deposition of sandstone, some particles of limestone which are present at the surface mixes with the sandstone so that's why in sandstone layer, small and weathered pieces of limestone are present.

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.
