<span>The right anwer is (b). Indeed, some scientists consider viruses as non-living because viruses do not undergo mitosis, which is the usual way living cells reproduce themselves. On the contrary, viruses inoculate their genetic material in a host cell in such a way to force the cell to make a copy of the virus DNA, thus making more viruses, that then kill the host cell and disseminate themselves. In practice the viruses exploits the replication tools of the living cells to replicate themselves, since they lack the machinery and also they lack something resembling cell metabolism, i.e., they do not "eat" or "grow".</span>

The right answer is b.viruses do not undergo mitosis.

*Viruses, like HIV, are able to multiply at high speed once they have parasitized a cell.

*By definition, a living organism is born, feeds, grows, reproduces and dies.

Since they are without metabolism, viruses appear to be closer to inert matter, although their reproduction binds them to life. So, the debate is still open regarding the classification of viruses among living or not.

Another term for the light-independent reactions of photosynthesis.
dolphi86 [110]

Answer:

A. The Calvin Cycle

Explanation:

The light-independent reactions cover half of photosynthesis, with the other half being the light-dependent reactions. Another word for this process is the Calvin cycle. It is named after the biologist, Melvin C. Calvin, who discovered it. The Calvin cycle is responsible for turning carbon dioxide into glucose. It also requires no light, hence its other name. Additionally, because it is occasionally called the Calvin cycle, sometimes, the light-dependent reaction is simply called the light cycle.

A laboratory study may help you to determine the location of your visual blind spot, but you will not notice it outside of the l
krek1111 [17]

Answer:

blind spot will not impair your vision

Explanation:

Blind spot may be defined as the point of our eyes where the optic nerve leaves our eye, which creates a "blind" spot as none of the receptor cells are located there.

A blind spot can only be studies in a laboratory because blind spot does not impair our vision. The blind spot falls on nose side of our retina, that means that the objects to our right side falls on the right eye's blind spot and objects to our left may fall on the left eye's blind spot. Thus, the blind spot  normally does not impair our vision, since our eyes are moving and because our one eye catches what the other eye misses.
