lakkis [162]

Answer:

Dominance Hierarchy

Explanation:

Dominance hierarchy is when the lead male and female are given preferential treatment to resources such as food and potential mates.

Dominance hierarchy forms as a way for animals to coexist in an environment where threats are constant and resources like food, water, mates, and shelter are limited.

Radda [10]

Answer:

The correct answer is: Clostridium Tetani.

Explanation:

Clostridium tetani is a Gram-positive bacteria found in soil.

<u>C. tetani may grow and generate </u><u>tetanospasmin</u><u>, a powerful toxin that interferes with </u><u>motor neurons</u><u>, producing </u><u>tetanus</u><u>, if introduced into a </u><u>wound</u>.

Tetanospasmin travels throughout the body via the lymphatic and bloodstream, where it is taken up by different sections of the nervous system. Tetanospasmin inhibits the release of the inhibitory neurotransmitters glycine and gamma-aminobutyric acid at motor nerve terminals in the nervous system. <u>This blockage causes </u><u>extensive motor neuron activation and muscular spasming</u>. These muscle spasms usually start at the top of the body and work their way down, starting about 8 days after infection with lockjaw and progressing to spasms of the stomach muscles and extremities. The muscle spasms last several weeks.

Tetanus toxoid vaccinations, which are often given to children around the world, can inhibit the toxin's activity.
