qaws [65]

The tetanus infection is considered to be a Droplet infection.

<h3>What is Tetanus?</h3>

Tetanus is a neurological disease which is characterized by the occurrence of spasms in the muscle.

Tetanus can be caused if initial care does not take place after the wound occurs and therefore, it is very important to immediately take care of the wound.

To treat the wound tetanus immunoglobulin and tetanus toxoids are given to the person, however, it is necessary to give the two injections using different syringes and at different sites, because the immunoglobulin can cause neutralization fo the toxoid.

Which of the following are thought to be most closely related to humans?
Oxana [17]

The correct answer is: sea stars

All animals listed above are invertebrates. One of the characteristic of invertebrates are that they are protostomes with the exception of Echinodermata (sea stars). The difference between protostomes and deuterostomes is in their embryonic development (orgin of mouth and anus).

In protostomes the mouth forms first: the oral end of the animal develops from the first developmental opening. On the other hand in deuterostomes the first opening (the blastopore) becomes the anus, and the oral end of the develops from the second opening.

Humans are also deuterostomes.
