How do the carbon and nitrogen sources affect the synthesis of β-(1,3/1,6)-glucan, its structure and the susceptibility of Candida utilis yeast cells to immunolabelling withβ-(1,3)-glucan monoclonal antibodies? Anna Bzducha-Wróbel, Pavol Farkaš, Sandra Bieliková, Alžbeta Čí...
How many neutrons does element x have if it's atomic number is 42 and it's mass number is 154?Question:How many neutrons does element x have if it's atomic number is 42 and it's mass number is 154?Atomic Number and Mass NumberThe atomic number refers ...
Atomic number:The number of protons in an atom's nucleus is referred to as the atomic number of that element. The number of protons defines what element it is and determines its chemical behavior. For example,carbon atomsalways have six protons;hydrogen atomsalways have one; andoxygen atomsalw...
(Table 6,Figure 2). As many as 67% of the collected soil samples were acidic or strongly acidic, of which 36% were soils with a pH below 4.5. Several studies have shown that crop production is limited when the soil pH levels fall below 5.5–6.0 because of the restricted availability ...
It's because the hydrogen and helium atoms are lighter than nitrogen atoms. They have fewer electrons, protons and neutrons than nitrogen atoms do, and that makes them lighter (the approximate atomic weight of hydrogen is 1, helium is 4 and nitrogen is 14). Approximately the same number of...
How does an atom try to fill its valence shell? If you know the atomic number and the mass number of an isotope of an element, how can you determine the number of protons and neutrons? Explain the concept of the mole. How many electrons does aluminium have? Calculate the number of mole...
The sun also emits energized particles (neutrinos, protons) that make up the solar wind. This energy strikes Earth, where it warms the planet, drives our weather and provides energy for life. We aren't harmed by most of the UV radiation or solar wind because the Earth's atmosphere protect...
摘要原文 Two completely flexible random chains containing N atoms joined by links of length L can be superimposed by rigid-body motions to match their structures as closely as possible. The statistics of the root-mean-square best-fit distance D are discussed. For long chains, D2 tends of 0.1...
When the neutron collides, a nitrogen-14 (seven protons, seven neutrons) atom turns into a carbon-14 atom (six protons, eight neutrons) and a hydrogen atom (one proton, zero neutrons). Carbon-14 is radioactive, with a half-life of about 5,700 years. For more information on cosmic rays...
