There are 4 types of viruses with different shapes. Tobacco Mosaic Virus - Rod-shaped due to its helical capsid. Adenoviruses - Icosahedral capsid with glycoprotein spikes edging out at each vertex. Influenza Viruses - Spherical. Outer envelope studded with glycoprotein spikes. Bacteriophage T4 - Consists of an icosahedral head, a long tail sheath and small tail fibers (leg-like appearance).
It is because viruses are not made up of cells
Viruses are made by tiny micro organism( germs) that basically float in the air or surround you. You can get it from people sneezing or being by an sick person/ etc.
Bacteria and viruses
Any other organelles, Or a cell membrane
Because HIV is a virus. Viruses have spikes because it is their way of reproducing.
spikes.
Your question is unclear but most spikes are made with materials other than gold.
The spikes you are referring to I am assuming concern viruses. They are located on the envelope surrounding the capsid, typically made up of the host cell material. The spikes themselves are of protein and match with receptors on the host cell. This is kind of like a key to a door. The virus sheds the envelope when entering the host cell, then sheds the capsid, releasing the nucleic acid (DNA/RNA) causing a viral infection to occur.
Bone.
i think its metal.
to run faster obviously
No, tissues are made up of cells and viruses are not even cells.
The Stegosaurus had very large, pointy spikes at the end of its tail. These spikes could have been used for defence against predators, like Allosaurus or Ceratosaurus. Its spikes were made of bone.
Inoculations (for immunization) are substances made from weakened viruses or bacteria.
The Stegosaurus's tail spikes are called thagomizers. They have a bony core but may have been covered in a thick layer of keratin.
Vaccines for the prevention of the specific viral infection can be made with inactive "dead" viruses. They are also made with live, but attenuated (weakened), viruses. See more below about vaccines.
