The answer is C. Exocytosis is when the vesicle fuses with to the cell membrane and releases its contents outside of the cell.
Kingdom Protista is probably comprised of groups of organisms that may not be closely related, and are undergoing continual assessment
<h3>What are the six - kingdoms of life?</h3>
The discovery of archaebacteria complicates the five-kingdom classification system for living organisms, which includes the prokaryotic Monera and the eukaryotic Protista, Fungi, Plantae, and Animalia. The prokaryotic Monera are divided into three groups: regular bacteria or eubacteria, cyanobacteria (also known as blue-green algae), and archaebacteria. Archaebacterial cell membrane lipids differ significantly from those of prokaryotic and eukaryotic cells, as do their cell wall composition and ribosomal RNA subunit sequence. Furthermore, recent research has revealed that archaebacterial RNA polymerases resemble eukaryotic enzymes rather than eubacterial RNA polymerase.
Archaebacteria have introns in some genes, an advanced eukaryotic feature previously unknown in prokaryotes.

Answer:
By way of introduction, A260/A280 ratio is use to measure Protein Contamination. This procedure was first described to measure protein purity in the presence of nucleic acids. However it is now commonly used to assess protein contamination of DNA. The method to determine the concentration of protein contamination by using A260/280 ratio method is well explained below by filling in the missing words.
Explanation:
The A260/A280 ratio method estimates protein __purity___ by measuring the absorbance maximum at 280nm caused by the amino acids__cytosine___, ____Adenine____, and ___Guanine_________ Since ___Spectrophotometer____ also absorbs in the UV range, we can correct for this contaminate by measuring the absorbance maximum at ____260nm______ and using the following equation: Concentration (µg/ml) = (A260 reading – A320 reading) × dilution factor × 50µg/ml___ When extrapolated from a standard curve, the Bradford data indicates the amount (in _ug__ ) of __unknown ___ protein found in a sample. If you know the volume of sample that was added to the assay then you can calculate the protein ____concentration ___ of the sample. The coomassie blue dye in the Bradford assay specifically binds primary ¬¬___sulfonic___ and __positive amines__ groups of the amino acid side groups of the proteins. The more the dye binds to the sample, the _anionic_ the blue color will be, and the absorbance at 595¬nm will be_shifted Amax___. A sample with an unusually __protein___ number of ___280nm of Tyrosine __ [give a specific example] amino acids will underestimate the total amount of protein present in the sample.
Atoms of different elements always combine in the same way.
John Dalton noted that if the components are added to one exacerbated, the share of their masses will dependably be the same. Dalton's been an English scholar. The component mass of that mix is measured by the confirmation of the presence of molecules assembled by John Dalton.
