Some bacteria use oil as their source. Before the oil spill waters of gulf has many bacteria of different phyla, immediately after the spill the bacteria of several phyla became less whereas bacteria of a particular phyla has increased. This shows that several phyla of bacteria were sensitive to bacteria whereas some able to persist the high doses of oil. Scientists after research identified the bacteria which is growing in the presence of oil and found that some bacteria feed on aromatic compounds which are very hard to break. Some examples of these bacteria are Colwellia, Neptuniibacter etc. Dispersants are used when workers want to stop the oil from spreading to a covered area like harbour or marsh. These dispersants are useful because oil is moved away from the habitat of the marine animals. The dispersant-oil mixture was colonised rapidly and was broken down by the bacteria that sunk towards the bottom. The dispersants helped the bacteria by exposing more oil to them.
Answer:
The correct answer is 1.
Explanation:
The metabolism of homocysteine produces a sulfur amino acid that is normally formed from methionine during the fulfillment of its function as a donor of methyl groups. Metabolic fate such as remethylation and transsulfuration, involving the enzymatic forms of the vitamins folacin, B12, and B6, gives rise to homocysteine and mixed disulfides including so-called protein-linked homocysteine, the main form circulating in plasma. B6 deficiency would have a direct impact on the metabolism of homocysteine to cysteine.
Have a nice day!
Answer:
C
Explanation:
Oil is less dense than water so it will always seperate and float on top of the water.
Answer:
LiOH (aq) + VCl3(aq) ---> LiCl(aq) + V(OH)3(s) - unbalanced
3LiOH (aq) + VCl3(aq) ---> 3LiCl(aq) + V(OH)3(s) - balanced
3Li+OH- (aq) + V3+(Cl-)3(aq) ---> 3Li+Cl-(aq) + V3+(OH-)3(s) - showing ions
3Li+(aq) + 3OH- (aq) + V3+(aq) + 3Cl-(aq) ---> 3Li+(aq) + 3Cl-(aq) + V3+(OH-)3(s) (some courses don't show the charges in insoluble ionic compounds - so V(OH)3(s)) - Showing soluble ionic compounds as separate ions.
3OH- (aq) + V3+(aq) ---> V3+(OH-)3(s) (or V(OH)3(s)) - without spectator ions
Explanation:
i don't know if this is right ore not but i hope this helps even if it is just a little bit sorry if this does not help i truly apologize
Answer:
d
Explanation:
Valence electrons are in the outermost shell. They form chemical bonds with other elements, not any other electrons. Hope this helps!
