Answer:
Tetanus patients exhibit <u>opisthotonos</u> when muscle spasms cause them to arch their backs.
Explanation:
Tetanus is a bacterial infection caused by the bacterium Clostridium tetani The disease causing bacteria is found in dust, manure soil and saliva. This infection is characterized by muscle spasms that start at the jaw and progress to rest of the muscles of the body.
Tetanus patients may also exhibit extreme arched pose due to severe muscle spasms. This state of hyperextension and spasticity is known as opisthotonus.
<span>Meiosis in simple terms is the process by which gametes (sperm and egg) fuse together to produce a fertilised egg. Haploid is a word that refers to how many chromosomes a certain cell has. In this case the gametes have a haploid number of chromosomes, which is half the number a normal cell has. A normal cell has a diploid number of chromosomes. So in meiosis the two gametes come together with their hapoid number of chromosomes each to create an egg that has a diploid (standard) number of chromosomes.</span>
Asexual reproduction creates offspring that are identical to the parent.
If the Na+ voltage-gated channels in a muscle cell open, the Na (sodium) ions rush inside the muscle cell and makes the cell more positive as Na ions carry positive charge on it. Due to the entry of positively charged ions inside the cell, the cell becomes less negative and more positive. This is called depolarization of cell.
The density of the water causes pressure, which causes water to move.
