Electromagntic wave, such as an X-ray.
Explanation:
- Electromagnetic wave does not require any medium to travel. These waves propagate outwards from the source.
- They can travel even through the vacuum of outer space.
- The major source is the sun which emits radiation in the form of the Electromagnetic spectrum.
- These waves travel through oscillating electrical and magnetic fields generated by the oscillating charged particles.
- These waves oscillate in the perpendicular direction of planes concerning each other and are in form.
- Electromagnetic waves travel at speed of light.
Answer:
Viruses can replicate inside cells, while bacteria release toxins to destroy cells.
Explanation:
Viruses and bacteria are both considered microorganisms that can be pathogens. Bacteria are singled celled organisms, where as viruses are non-cellular. Therefore, viruses are sometimes considered non-living, or "on the edge of life"
Viruses consist of (at the minimum) a genome surrounded by a protein coat. To replicate, they have to insert their genome into a host cell. This is another reason they are sometimes considered non living.
In contrast, bacteria can release toxins but do not replicate inside cells.
Therefore, the answer is viruses can replicate inside cells, while bacteria release toxins to destroy cells.
