prokaryotic cells most likely bacteria or virus, etc.
It is difficult because viruses lack the ability to replicate themselves and theey lacks energy metabolism and other pathways that living things have. Viruses are totally depending on their host. If they want to replicate, they have to infect the host.
Lassa fever is a virus. It does not have a gram stain characteristic.
A solid that lacks the long-range order that is characteristic of a crystal. In some older books, the term has been used with glass
All matter has mass, and takes up space. Any other observed physical phenomena is defined as energy.
nope a virus requires a host cell in order to replicate. it lacks the mechanisms to reproduce copies on its own
the best characteristic of it is that it can change it's protein code,whenever it requires ..which is why it can fool our immune system.
No virus no matter what kind can perform metabolic activities independently.
Bacteria lacks a nucleus but have a fully developed DNA, thus they can be considered full cells. Virus also lack a nucleus, but they have not a fully developed DNA. Even virus having RNA only exist. For this reason virus are somehow in between cells and simple multiple molecular systems.
