Answer:
The most appropriate answer would be "evidence of changing environmental conditions, with references".
As Mr. Potts claimed that great variations in environmental conditions over time were responsible for the adaptability of humans and the success of our species in his paper, he must have mentioned evidence of changing environmental conditions with references.
In addition, he must have shown the effects of changing environmental conditions on the adaptations made by human species due to those changes.
<span>True. The external air is empty until the ear drum, passing through into the middle ear by way of three small bones that vibrate against each other and into the inner ear, where sound vibrates through the bony labyrinth, all encased in a fluid that helps the sound move to sound detecting nerves in the inner ear.</span>
Answer: Botulism (Clostridium botulinum)
Botulism is caused by
a bacterial infection specifically <span>Clostridium botulinum,
an anaerobic, gram-positive spore forming rod, whose spores survive in soil and
water. This toxin acts by blocking nerve
function by inhibiting release of acetylcholine neurotransmitter that results
to muscular rigidity and spasms of respiratory, laryngeal, and abdominal
muscles, which may cause respiratory failure. </span>
