Infection occurs when the host is exposed to pathogens. what type of pathogen uses the cell's metabolism, and replicates itself
vladimir1956 [14]

Answer: Infection occurs when the host is exposed to pathogens. virus uses the cell's metabolism, and replicates itself while destroying the cell or changing the cell's genetic makeup.

Explanation:

  • A virus is a miniscule pocket of protein that contains genetic material.
  • Viruses pose a considerable challenge to the body’s immune system because they hide inside cells.
  • This makes it difficult for antibodies to reach them. Some special immune system cells, called T-lymphocytes, can recognise and kill cells containing viruses, since the surface of infected cells is changed when the virus begins to multiply.
  • Many viruses, when released from infected cells, will be effectively knocked out by antibodies that have been produced in response to infection or previous immunisation.
  • Antibiotics are useless against viral infections.  So antiviral drugs work differently to antibiotics, by interfering with the viral enzymes instead.

Hence virus are the pathogen that use the cell's metabolism. And replicate itself while destroying the cell or changing the cell's genetic makeup. viruses are so simple that they use their host cells to perform their activities for them

Which of the following soil conservation techniques prevents erosion?
nydimaria [60]

All answer choices are correct in soil conservation techniques prevents erosion.

<u>Explanation:</u>

  • Decreasing tillage yields crops to settle in the soil preferably than being broken at the end of a season. The gain of no-till farming is consecutive to the soil structure, which transmits more deposits on the exterior to stand up against severe water and wind situations.
  • With contour ploughing, preferably of seeding crops in straight lines, crops are planted based on the form lines of the area to form stores that save rainwater and lessen top-level soil erosion.
  • Terracing is the habit of producing almost level areas in a hillside area.  Terraces are shielded from erosion by other soil restrictions.

How do enzymes catalyze chemical reactions (don't just say "they lower the activation energy", give me specific mechanisms)?
Rina8888 [55]
They do lower the activation energy but they provide an alternate pathway for the reaction to happen quicker and they do not get used up in the reaction
