Nonliving characteristics include the fact that they are not cells have no cytoplasm or cellular organelles and carry out no metabolism on their own and therefore must replicate using the host cells metabolic machinery. Viruses are filterable facultative parasites.

Viruses can only replicate within living cells in the body of the host and cannot multiply in foods.
. 20 Which of the following is NOT a characteristic of viruses. Which of the following is NOT a characteristic of a virus. The presence or absence of an envelope is not useful in classifying viruses because any given virus may at one time have an envelope and at another time not have an envelop.
Viruses are usually considered to be nonliving. Which of the following is not characteristic of a bacteria. A nucleic acid genome.
A They are not composed of cells. Based on the general composition nucleic acid RNA and DNA the viruses are classified into two categories. Bacterial viruses are so named because they have the same procaryotic cell structure as their bacterial host.
Some viruses have cellular structure and are saprophytes. However there are some general structural characteristics that all viruses share. May have a slime coat.
Solution for HIV is a virus that infects human beings which of the following is not a characteristic of this particular virus. A relies on a host-cell metabolism b has a nucleic acid core surrounded by protein c contains only one or a few enzymes d relies on the hosts reproductive capabilities to spread e contains both DNA and RNA. It is a tiny particle much smaller than a prokaryotic cell.
A virus is malicious code that is attached to a legitimate program or executable file and requires specific activation which may include user actions or a time-based event. C They cannot reproduce themselves outside of a host. Which of the three domains of life do viruses belong to.
They dont show growdevelopment nutrition reproduction etc. Living characteristics of viruses include the ability to reproduce but only in living host cells and the ability to mutate. Viruses do not meet most of the criteria of life.
Viruses are minute organisms smaller than bacteria and parasites and are too small to be seen directly with a light microscope. C They are acellular. All viruses known to man are obligate parasites.
Three examples of viruses can be seen in Figure 101. Because most viruses are extremely well adapted to their host organism virus structure varies greatly. Cause infections in body fuids.
Solution for Which of the following is characteristic of all viruses. Viruses are much smaller than prokaryotes ranging in size from about 20300 nanometers. IT can affect all living organisms ie.
Up to 24 cash back Viruses form an unique bridge between living and non-living things with those characteristics. It can be converted to be a. The outside of the cells act like an inert chemicals.
An individual virus is called a virion. Living characteristics of viruses include the ability to reproduce but only in living host cells and the ability to mutate. Viruses are living and bacteria are non -living.
Up to 24 cash back CHARACTERISTICS OF VIRUSES A virus is a tiny bundle of genetic materialeither DNA or RNAcarried in a protein shell called a capsid. Humans plants animals etc. They are not even made of cells.
Bacteria are living and viruses are non -living. E All of the above. They can be crystallized.
The envelope is made of a lipid. A virus can execute independently of the host system. A virus is a sub-microscopic particle that can infect living cells.
A They are composed of genetic material and protein. D They are visible with a light microscope. A virus is an infectious agent which needs a host or living cell to replicate itself.
They can multiply within host cells. Which of the following is not characteristic of a virus. One of the differences between bacteria and viruses is that.
When activated a virus can infect the files it has not yet infected but does not automatically. Some viruses have an additional layer around this coat called an envelope. A second inviolate characteristic of viruses is that they do not reproduce through binary fission which is an asexual reproduction technique in which pre-existing cells split into two identical daughter cells.
The capsid is made of proteins and glycoproteins. B They are chemically simple. All viruses have a capsid or head region that contains its genetic material.
Which of the following is NOT a characteristic of a virus. RNA or DNA core. D Viruses are obligate intracellular parasites.
Nonliving characteristics include the fact that they are not cells have no cytoplasm or cellular organelles and carry out no metabolism on their own and therefore must replicate using the host cells metabolic machinery. A viral envelope C. C Viruses are not composed of cells.
E They are smaller than prokaryotic cells. It cannot be cultivated in a lifeless media and cannot grow outside the living cell. They can be precipitated.
Viruses are biotic and bacteria are abiotic. 42 Which of the following provides the most significant support for the idea that viruses are nonliving chemicals. Viruses are prokaryotic and bacteria are eukaryotic.
Because viruses do not consist of cells they also lack cell membranes cytoplasm ribosomes and other cell organelles. Viruses are capable of performing metabolic activities on their own. Without these structures they are unable to make proteins or even reproduce on their own.
B They are obligatory parasites.
