Why aren’t your cells poisoned to death even though they create toxins?
Orlov [11]

Answer:

Our cells are not poisoned to death because it is metabolized by our organs.

Explanation:

  • Toxins are any chemical products that damages the functioning of our body.
  • To be more specific, human body do not produce any toxins. They only discrete the waste materials that are easily secreted by our body through the metabolic activities.
  • Organs like liver and kidneys are responsible for fighting against the harmful waste products and toxins by throwing it out from our body.

A living cell is placed into a hypotonic solution . Compare the solute and solvent concentration inside the cell with the concen
frosja888 [35]
<h2>Answer:</h2>

The living cell concentration is hypertonic than outer solution hence the concentration of solutes will be higher than the solvent.

<h3>Explanation:</h3>
  • In the question description it is mentioned that cell is present in the hypotonic solution than cell environment will be hypertonic.
  • In the cell the solute will present in the concentrated form.
  • Hence the water will move from the outer environment into sell through the osmosis.
  • Osmosis is the movement of water from higher concentration to low concentration through semi permeable membrane.
  • Hence the cell will swell due to water collection in cell.

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>
