Discuss why we see an increase in boiling point with larger alkane molecules. How do you determine the intermolecular force of a substance? Which physical properties of a substance are influenced by the strength of its intermolecular forces? Describe the differe...
Describe one of the experiments that helped to determine the subatomic particles. Be as detailed as possible. Which of the following statements best explains why J.J. Thompson's Plum Pudding model had to be revised? a) Experimental evidence showed that ...
Meat and flesh are an important source of proteins, essential amino acids (AAs), essential fatty acids (FAs), minerals, and vitamins (A, E, and B), which determine nutritional quality. The AA profile is relatively constant between muscles or between species [72]. However, collagen-rich musc...
By comparing the average scores of four different tests of memory and perception, the researchers were able to track change in cognitive function with age. The participants also completed dietary questionnaires periodically, which enabled the researchers to determine their vitamin E intake. The study f...
B) Give the hybridizations of the following atoms in the structure: (i) Ca (ii) N (C) Give approximate values of the following bond angles: (i) Ha What three elements can hydrogen bond with to create the IMF of hydrogen bonding between molecules? What is the bond angl...
IMF content can also be a good indicator of juiciness. Thompson (2004) found that consumers were satisfied and dissatisfied with beef juiciness when IMF was above 20% or below 2%, respectively [103]. However, it is difficult to define a threshold of juiciness for consumer perception based ...
Metabolomics refers to the set of low molecular-weight molecules (<1.5 kDa) biosynthesized by the cells in association with its metabolism, defined as the metabolome [32]. Providing a snapshot of the metabolic phenotype at a given time, metabolomics has the potential to determine biomarkers ...
In a cotton-tomato rotation, conservation tillage noticeably decreased dust emissions due to fewer field operations [182], and long-term sampling is necessary to determine the effects of cover crops on dust production. 4.9.2. GHG Emission In the North China Plain, when compared to CT, NT ...
We have used the AEA antagonist SR141716A (rimonabant [104]) to determine the involvement of CB1 in the cytotoxicity induced by AEA. In these experiments, SH-SY5Y cells were incubated with AEA in the presence of increasing concentrations of the antagonist and mitochondrial cytotoxicity was ...
Again, because of the small numbers of individuals with progeria, childhood cancers might be too scarce to determine whether the genetic mutation lowers the number of organ-specific adult stem cells so as to lower the risk of childhood cancers, as well as the endogenous growth factors or ...
