It maintains homeostasis by controlling the body's temperature and releasing excess heat through sweat.
According to ChaCha.com, "Parthenogenesis is a form of agamogenesis in which an unfertilized egg develops into a new individual. Parthenogenesis occurs naturally in many plants and invertebrates. This differs from other forms of asexual reproduction because an egg is used."
Answer:
1. B - Aa x Aa = 25% chance AA, which is the only genotype that results in sickle-cell. Aa is called "sickle-cell trait'; it isn't the full disease.
2. A - Aa x aa = we know will produce no homozygous dominant
3. B - RR x Rr = 1/2 chance of Rr (same problem as #5)
4. A - Bb x Bb = 1:2:1 ratio
5. B - WW x Ww = 1/2 chance of Ww
6. D - AABbCC has 5 dominant alleles, which is the most out of the four options
7. C - the one with the fewest dominant alleles will be the most green and the most successful in the environment
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.
