Answer:

the difference in its enrichment

Explanation:

Although both the atomic bomb and nuclear reactor can use uranium fission to produce heat, the base material has differences. We explain to you what uranium enrichment is.

The difference is in enrichment. Not all uranium extracted in nature has the characteristics that allow it to produce energy, either to convert to electricity or to explode a bomb. Therefore it is necessary to concentrate the type of uranium most favorable to this reaction, that is, to enrich it.

Uranium is a heavy chemical element with 92 protons in its nucleus but with a varying number of neutrons. Each uranium atom that has a different number of neutrons is an isotope - the most common are uranium-238, with 146 neutrons in the nucleus, and uranium-235, with 143 neutrons. And it is this isotope of uranium, 235, that is most interested in nuclear reactions because it is more unstable.

Of the uranium that is taken from nature, only about 0.7% is uranium-235. Enrichment implies that uranium-238 is separated and that the proportion of uranium-235 in a sample is increased. If the goal is to produce electricity, the proportion of uranium-235 need not exceed 5%, for scientific research reactors it should be close to 20%, but to produce nuclear weapons uranium must be enriched at least 90%.

Hi! :)

The amount of uranium within nuclear fuel rods is enough to sustain a chain reaction but is less than the critical mass necessary for the reaction to become explosive.

Alja [10]

Answer:

She will add color dye to antibodies, and the antibodies will attach to the antigen of the pathogen.

Explanation:

Immunostaining is the process where the antibodies for a specific pathological antigen is combined with fluorescent dye or any other indicator, like enzyme. Fluorescein are common staining materials used because it is easily detectable under UV light. This antibody coated with indicator thus bind to the specific pathogen or protein and help in its identification. Also the pathogenic cell fixation is done to facilitates clear and precise identification.

ElenaW [278]

<em>A) near warm water.</em>

<h3><em>Hurricanes, also called tropical cyclones form in seven distinct basins around the world. Some hurricane formation basins are much more active than others. Some tropical cyclone basins also have conditions in which tropical cyclones may occur over longer periods during the year. Most tropical cyclones form from a disturbance in the monsoon trough. The north Atlantic basin is considerably different, as the majority of hurricanes form from easterly waves originating from Africa. Hurricanes and typhoons only can form over large basins of warm water such as an ocean or gulf. This is due to the fact that they need a large amount of energy which is supplied by the heat from the warm ocean waters evaporating into the atmosphere. Hurricanes also occur at least several degrees away from the equator. This is because the Coriolis force is too weak at the equator to generate spin for the hurricane to develop. </em></h3>

Svetach [21]

Answer:

The lands were subdivided equally amongst sons alone

Explanation:

The policy of partible inheritance is a system of inheritance in which any given property is apportioned amongst heirs. It became a generally accepted form of inheritance for New Englanders in the seventeenth century.
