Sodium chloride is mixed with water?
When NaCl is placed in water, the sodium and chlorine dissociate, giving you ions of chlorine which are negatively charged, and sodium ions which are positively charged. There is no reaction when sodium chloride is placed in water.
How is recombinant DNA transffered?
Recombinant DNA can be transformed (you meant transferred) in to the bacterium by heat shock treatment or by electroporation. Cloned rDNA is normally mixed with the competent cells prior to this. Transformation cause the entry of the plasmid DNA into bacterium. They cultured for a while and plated against antibiotics to isolate transformants.
Which test involves placing samples of an unknown bacterium in saline adding different antisera and checking for clumping?
The test you are referring to is called the slide agglutination test. In this test, samples of an unknown bacterium are mixed with different types of antibodies (antisera) and observed under a microscope. If the antibodies react with the bacteria, clumps or aggregates will form, indicating a positive result.
What happened when salt dissolves in water?
The negatively charged ions (Cl-) and the positively charged ions (Na+) become solvated which is the process where a solute dissolves. The ions are surrounded by solvent molecules (water). For water bonds the oxygen is slightly negative and the hydrogen molecules are slightly positive; the shared electrons are pulled closer to the oxygen. The sodium ions are attracted to the oxygen's negative charge and the chloride ions are attracted to the hydrogen's negative charge.
What type of molecules mix the best with water?
Molecules that are polar(charged) dissolve best in water, while nonpolar molecules do not dissolve well in water.
If one body is positively charged and another body is negatively charged what do free electrons tend to do?
Free electrons tend to move away from the negatively-charged body and toward the positively-charged body.They will transfer to the positively charged body in an attempt to create a neutral charge.Move from the negatively charged body to the positively charged body.move from the negatively charged body to the positively charged body!-----------I just finished the Penn Foster test, and the answers for a 100 are (from left to right):A D CA C BD B CC D DD C CA B DC A BD A C Byou actually had two of the answers mixed up but i fixed them--after i got them wrong on my test. so now its 100%
What happens to the hydrogen ions released by acids in water?
Hydrogen ions mixed with water(H2O) atoms to form positively charged hydronium(H3O+). The other product is the cation of acid.
Can a bacterium that ferments using the 2 3-butanediol pathway use the mixed acid route?
Yes, but the PH will not fall as low as with the mixed acid route. The PH is an indicator of the route the bacterium used to ferment.
What is mixed skin flora?
Mixed skin flora is a bacterium that attacks the skin. The condition is from microorganisms that are already on the skin. The condition is not serious and can be treated easily by your primary care provider.
How does the advancement of communication affect us both negatively and positively?
communication has affected us negatively and positively. The way it has affected us negatively is by it can get mixed up while being sent. The way it has affected us positively is by the way it it faster
Sodium chloride is mixed with water?
When NaCl is placed in water, the sodium and chlorine dissociate, giving you ions of chlorine which are negatively charged, and sodium ions which are positively charged. There is no reaction when sodium chloride is placed in water.
Can a bacterium that ferments using the 2 3 butanediol pathway also use the mixed acid route?
Yes.the use of the pathway decreases acid formation and causes the formation of a distinctive intermediate known as acetoin
What does it mean when a guy gives you mixed signs?
It implies the guy exhibits mixed emotions which may range from optimistic to passimistic views,not certifying your actions positively but there's something other matters may not be acceptable to you.
How much do mixed animal veterinarians earn?
The average annual salary for a veterinarian in the United States is ~US$90,000; a mixed animal veterinarian would tend towards this average.
What are the strengths and weaknesses of Dalton's atomic model?
strengths: -electrons move fast through the atom. -electrons are trapped within the atom by a positively charged nucleus -electrons are negatively charged. weaknesses: -failed to discover the nucleus contains positively charged particles called protons -failed to discover the nucleus also contains neutrons (a sub atomic neutral particle)
How is sodium formed?
Sodium chloride is a salt, meaning that it is a chemical compound that consists of a positively charged cation, in this case the sodium ion, and a negatively charged anion, in this case the chloride ion.Sodium chloride is an easily soluable salt, so when it is mixed into water, it will turn into chloride and sodium ions. Reversibly, when the water is evaporated from a solution containing sodium and chloride ions, sodium chloride will form.An example of the formation of sodium chloride is when the strong base sodium hydroxide (NaOH) and the strong acid hydrochloric acid (HCl) are mixed into the same solution, which is then evaporated:NaOH (aq) + HCl (aq) => Na+ (aq) + Cl- (aq) + H2O (l) => NaCl (s) + H2O (g)
