They contain genetic information needed to produce more viruses in the form of DNA or RNA.

Explanation:

Viruses are extremely small infectious agents that invade cells of all types. Once inside another cell, viruses become hijackers, using the cells' machinery to produce more viruses. Whether viruses constitute living organisms or merely conglomerations of molecules has been a source of debate for many years. One of the fundamental hallmarks of life is the ability to reproduce. Whether viruses have this ability is key to a debate over their status as living things. Some argue that since viruses cannot reproduce independently, they are not alive. However, similar to viruses, there are a few prokaryotes that are obligate parasites and cannot reproduce without a host. But these prokaryotes show another hallmark of life that viruses lack: growth. Once assembled, a virus does not change in size or chemical composition. They lack the machinery for producing energy to drive such biological processes. This makes them radically different from any known organism. Viruses do, however, show some characteristics of living things. They are made of proteins and glycoproteins like cells are. They contain genetic information needed to produce more viruses in the form of DNA or RNA. They evolve to adapt to their hosts. So while it is doubtful viruses are truly alive, they are clearly very similar to living organisms. There is more diversity among viruses than among all groups of living organisms combined. New varieties are constantly being described. It would be nearly impossible to describe all of the groups of viruses and their characteristics briefly. Instead, we will look at the characteristics shared by all viruses, such as their basic structure and general replicative cycle. Then we will discuss the features used to classify new viruses, such as shape and form of genetic material.

cell-based life.

Explanation:

Still, viruses have some important features in common with cell-based life. For instance, they have nucleic acid genomes based on the same genetic code that's used in your cells (and the cells of all living creatures). Also, like cell-based life, viruses have genetic variation and can evolve

Answer from: Quest

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

Look at the pendulum diagram between which points does the pendulum’s potential energy increase most

Answer from: Quest

the right answer is 0.3 meters per second

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.

The rocket is fired vertically and tracked by the radar station shown. when θ reaches 66°, other corresponding measurements give the values r = 32700 ft, r¨ = 85 ft/sec2, and θ˙ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.
