Answer:
The atomic mass is the number of protons, plus the number of neutrons. In this case, 8 + 6 = 14.
Explanation:
The six protons (atomic number) tells me that this is carbon; the six electrons tell me that this is a carbon atom, rather than a carbon ion (an ion is when the number of electrons does not equal the number of protons, making the atom electrically non-neutral). The eight neutrons tell me that this is an isotope (in other words, a version) of carbon called carbon-14, which happens to be mildly radioactive; and therefore useful to archaeologists in dating human artifacts.
The given question is incomplete.The complete question is T/F When performing column chromatography to purify a protein of interest, one needs an assay to identify which fractions that contain the protein of interest. True or False: As discussed in lecture, we use a different assay for each different protein that we purify (For instance, the assay for protein A will be different than the assay for protein B which will be different than the assay for protein C, etc).
Answer: True
Explanation:
The sample contains different types of proteins in it and when the sample into chromatography column.
Different proteins have different affinity and based on the molecular size and weight they are separated.
So, according to the question if some one wants to assay protein A, it will be different for the protein B and different for the assay of protein C. This means that assays for different proteins will be different.
Hence, the given statement is True.
Answer:
True: D. Simple steps like handwashing and not working with food when sick can help prevent foodborne.
Explanation:
It is false that most foodborne illness is not preventable, they are actually easy to prevent if we follow some recomendations, such as handwashing. Also, not most foodborne illness is caused by vectors, we have 3 categories of: biological hazards, chemicals hazards and physical hazards. It is false that safe handling involves many complicated procedures that require advanced education and training, it is pretty easy. Just by following four steps you get a perfect handwashing.
Answer:
it would be an increase of plant life
Explanation:
the reason for this is that plants take up the carbon dioxide and give us fresh o2
