Viruses are composed of two main parts: an outer protein covering called a capsid and an inside core of either DNA or RNA. Not both DNA and RNA. Some of these have an envelope over the capsid. The ones that do not are said to be naked. The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell. The naked viruses are more resistant to changes in the environment.

What two viruses can impact living things?
polivirus-causes polio and adenovirus-affextss the adenoids
What are the two ways viruses multiply?
When they are inside other living things and the other one I have no idea
What are two things make viruses different to plants and animals?
1. they don't have cells, virus is a chunk of nucleic acid with a protein coat. 2. most viruses are destructive and they reproduce inside living things.

What two things are used to classify viruses?
Shape,Genetic material,Precense of reverse transcriptase enzyme,Host
Are two by fours made from more than one type of wood?
No, two by fours are typically made from a single type of wood, typically softwood such as pine, fir, or hemlock.
What are two things that make viruses hard to fight?
The two things are: 1. Viruses behave as living beings only inside another living cell and act as a non living thing when isolated or outside the living cell. 2. The genetic material of a virus is RNA not DNA which is gives complexity in its study.
What is the two different lifecycles exhibited by viruses?
The two different lifecycles of viruses are Lytic and Lysogenic
Why cant you use antibiotics to kill virus but bacteria can be killed by antibiotics?
Because bacteria and viruses are two completely different things. Antibiotics - as their name implies - will kill bacteria, but antibiotics simply have no effect on viruses.
Are ants made out of cells?
All living things large enough for you to see are made out of many cells, including ants. Some of the animals and plants that are too small for you to see are made out of just one cell each. Viruses are not made out of cells, but it is a tricky question to argue whether a virus is a living thing or not. For the purposes of this question I suggest you assume that viruses are not truly living things. This principle that "All living things are composed of cells and cell products" was first discovered and suggested by two scientists called Schleiden and Schwann. It is called the cell theory, and is one of the most important discoveries of modern biology.
What are two things made during cellular respiration?
Two by-products of cellular respiration are carbon dioxide (CO2) and water (H2O). Energy is also released. The inputs are typically organic compounds like glucose, and oxygen (O2).
What two things make up a virus?
Viruses are just protein shells that in some cases contain RNA and in others it's DNA.
