Answer:
The answer is Lysis.
Explanation:
The steps of the act of a virus using the cell as a host are correctly given in order in the question and the cycle/step that causes the immediate death of the hosting cell is in the last step, "Lysis". Which is the step where the virus is done using the host cell for reproduction purposes and by releasing certain chemicals, disintegrates the wall of the hosting cell to be able to get out therefore causing the death of the host in the process.
I hope this answer helps.
Explanation:
c. Water leaves the sucrose solution because the sucrose molecule is a disaccharide and thus larger than the monosaccharide glucose.
d. The sucrose solution is hypertonic and will gain water because the total mass of sucrose is greater than that of glucose.
e. After the sucrose dissociates to two monosaccharides, water will be osmostically drawn to that side of the membrane.
Answer:
a. Nothing happens because the two solutions are isotonic to one another.
Explanation:
Two solutions of the same molarity are separated from each other by a membrane that allows water molecules but not the glucose or sucrose to move across it. Movement of water across the selectively permeable membrane occurs only when two solutions have different concentrations of solutes. In that case, water moves from a hypotonic solution towards a hypertonic solution. Since both sucrose and glucose solutions have the same tonicity, there would not be any change in the solution.
b. The relationship between a lion and a zebra.
c. The relationship between a bee and a flower.
d. The relationship between a hen and a rooster
Answer:
Air cells of dough are filled with CO2.
Explanation:
Flour, water and yeast are important parts of bread dough. When we mix these the yeast enzyme will breakdown the satarch into simple sugars and metabolize the sugars to produce CO2 and ethyl alcohol into the existing air bubbles in dough.
Fermentation helps in producing the strong and elastin gluten to held the CO2 within the bubbles and inflate it. The more the air cell filled the more will be the bread dough rise.
Answer:
Presence of CO2 in the dough.
Explanation:
Yeast cells thrive on simple sugars. As the sugars are metabolized, carbon dioxide and alcohol.
chemical process known as fermentation.
Equation of Fermentation reaction:
C6H12O6(s) --> 2C2H5OH(aq) + 2CO2(g)
Tiny air cells fill with carbon dioxide are released into the bread dough, making it rise.
Answer:
The answer to this question would be: antiviral agents that block any of the steps in the transcription process, since without newly produced RNA, or DNA for the new virions, it would be impossible for the virus to replicate itself and thus spread out to infect further. An example of such a drug is aciclovir, and what they do is inhibit, or prevent, the transcription process, either of DNA, or RNA depending on the invading virus, so that viral proteins cannot be coded for and the new virions cannot be assembled.
These agents usually are nucleotide analogues that mimick the DNA, or RNA, that the virus will need in order to replicate its genetic material for the new viruses. However, since they are not the correct material, these analogues will inhibit correct replication, or further coding, of the genetic material. This in turn will ensure that either no proteins, or weak proteins, will be produced and the virus will be left weakened for the attack of the immune system.
