Why can’t a virus reproduce on its own?

Biology

7 0

Answer:

<h3>Viruses can only replicate themselves by infecting a host cell and therefore cannot reproduce on their own.</h3>

<h3>At the most basic level, viruses consist of genetic material contained within a protective protein coat called a capsid; the existence of both genetic material and protein distinguishes them from other virus-like particles such as prions and viroids.</h3>

<h3>They infect a wide variety of organisms: both eukaryotes (animals, fungi and plants) and prokaryotes (bacteria).</h3>

<h3>A virus that infects bacteria is known as a bacteriophage, often shortened to phage.</h3>

<h3>The study of viruses is known as virology, and those who study viruses are known as virologists.</h3><h3 /><h3>It has been argued extensively whether viruses are living organisms.</h3>

<h3>Most virologists consider them non-living, as they do not meet all the criteria of the generally accepted definition of life.</h3>

<h3>They are similar to obligate intracellular parasites as they lack the means for self-reproduction outside a host cell, but unlike parasites, viruses are generally not considered to be true living organisms.</h3>

<h3>A primary reason is that viruses do not possess a cell membrane or metabolise on their own - characteristics of all living organisms.</h3>

<h3>Examples of common human diseases caused by viruses include the common cold, the flu, chickenpox and cold sores.</h3>

Why do Canadians pay much less for treated water.
lesya692 [45]
Canada, one of the wealthiest countries in the world, is also one of the most water-rich. The province of Ontario shares the Great Lakes—which contain 18 percent of the world’s fresh surface water—with the United States. Access to sufficient, affordable, and safe drinking water and adequate sanitation is easy for most Canadians. But this is not true for many First Nations indigenous persons. In stark contrast, the water supplied to many First Nations communities on lands known as reserves is contaminated, hard to access, or at risk due to faulty treatment systems. The government regulates water quality for off-reserve communities, but has no binding regulations for water on First Nations reserves.
