Describe the difference between the lytic cycle and lysogeny when bacteriophage infection occurs.
Shkiper50 [21]
Both are methods of viral multiplication inside the host cell.
 Lytic cycle (which is more common) includes steps like:
<span>1. Infection of the host cell-virus attaches to the receptor of the host cell, penetrates it and releases its genetic material into the host cell.</span>
<span>2. Virus Multiplication-Virus incorporated its genetic material into the host’s and uses its metabolism to multiply. Viral genetic material replicates separately from the host DNA.</span>
<span>3. Cell Destruction-  Virus releases an enzyme that breaks the cell wall from within, thus destructing the host cell.</span>  
<span>Lysogenic cycle also includes steps of infection, penetration and incorporation of the genetic material. But, after the virus integrates its genetic material it becomes dormant, letting the host multiple and continue its normal activities. Viral genetic material replicates within the host DNA during the host cell's division, so the daughter host cells are infected too.<span> At some point, the virus is triggered, it multiplies and ultimately, destroys the host cells.</span></span>

Anni [7]
<h2>Blood is forced upward and toward</h2>

Explanation:

  • In the cardiovascular cycle, the autonomous withdrawal and unwinding of heart cells are facilitated through the movement of the heart's characteristic conduction framework and by cell-to-cell correspondence by means of the hole intersections in the myocardial cells themselves.  
  • The natural conduction arrangement of the heart comprises of nodal tissue, whose specific cells have both apprehensive and solid qualities. Nodal tissue is restricted in explicit areas of the heart.

Advocard [28]

Answer: Her body begins doing cellular respiration

Explanation: She needs her electron transport chain to function to produce 34+ ATP. The E.T.C. Needs oxygen to work, so she needs to increase her oxygen input. She breathes more to increase the flow of oxygen. Her heart also beats faster because she needs more oxygen to spread to her body.

(b) Vaccination against the measles virus will not protect the child against the rubella virus. Why?
vekshin1
The measles virus and rubella virus are two separate viruses. They have different DNA and RNA structures, and the vaccination for the measles virus only "knows" how to attach itself to measles and destroy the virus. It doesn't know how to attach itself to the rubella virus to destroy it, as the vaccination is needed to inform it how to.

The advantage of vaccinating a large amount of the population is that it reduces the chance someone will catch sickness by a great amount, and can possibly eradicate the virus.
