Answer:
C Halobacterium species
Explanation:
ThIs is because this species of bacteria thrive well in high salt concentrations; and will be inactive in a low salt concentration medium.They are known as Hallophilic Organisms. (salt organism)s
They are rod-shaped, motile organisms , which reproduced by binary fission,live in saline lakes, with the cell bounded by a single layer of plasma membranes.They contain beta-caroteen pigments. it is this that is responsible for their red coloration.When this pigment is extracted, is used in food dye. giving food red coloration.
In addition, Halo. Bacteria contain some enzymes that can break dowm organic molecules to simplest forms. These are Degredative enzymes.(e.g Lipase , Amylases). it is this feature that aids their application for aiding the process of fermentatio<u>n of salty foods</u>, and also aiding of <u>coffee processing during production. </u>
<u>Since this is called a salty bacterium, and its enzymes will be most active in high salty concentrations, then option C is the correct answer.</u>
There are often not more than one or two independent variables tested in an experiment, otherwise it is difficult to determine the influence of each upon the final results. There may be several dependent variables, because manipulating the independent variable can influence many different things.
Answer:
The relationship between an organism's DNA and protein specificity is that DNA determines the amino acid sequence of each protein (option D).
Explanation:
Each organism's DNA molecule is formed by a specific sequence of nitrogenous bases that not only determine the amino acids that a synthesized protein will have, but also the order in which these amino acids will form the protein structure.
The steps in which this occurs can be summarized as follows:
- <em>The sequence of nitrogenous bases of a DNA strand is transcribed into the mRNA, which will go into the cytoplasm.
</em>
- <em>The sequence of bases in the mRNA is organized into triplets of bases, called codons, each of which encodes a specific amino acid.
</em>
- <em>During translation, each codon will indicate the amino acid that will be coupled to a protein molecule in a specific order.
</em>
According to this, the<u> DNA </u><u>determines the </u><u>amino acids sequence</u><u> that will be in a </u><u>specific protein</u><u> molecule</u>.
