These are called papillae
Answer:
There are prion-like particles in the brain normally, and when these become abnormal they can cause disease. (Ans. A)
Explanation:
Prions are proteins which can trigger normal proteins to fold abnormally, and they are present in the brain. They are causing many types of neurodegenerative diseases in both humans and animals. Which are known as transmissible spongiform encephalopathies.
Prions can enter the brain with the help of infection, also can arise from the gene mutation that encodes the proteins, and sometimes this affects humans by infected meat.
If a person infected from prion disease, it affects central nervous system tissues like brain, eye tissues and spinal cord.
None of them.
I'm assuming that you left off an option. a prokaryotic cell is a single-celled organism, generally a bacteria. an example would be e-coli.
The final product of Meiosis is haploid daughter cells in which each cell has 23 chromosomes. What happens in meiosis is that, the cell is divided twice and this produces four daughter cells. During this process that our sex cells are produced. So the answer for this would be option D.
