The Skeletal system helped him move his hand away from the hot object.
Explanation:
The Skeletal system consists of our skeleton or the bones. The other options would be correct if the question asked about the<u> nervous system</u> instead of the skeletal system.
Answer:
Reproductive isolation occurs faster in deep-water shrimp than shallow-water shrimp.
Explanation:
Though in the same territory, the blockage caused by the isthmus would quickly and permanently isolate shrimps living in the deeper parts of the water, thus making them unable to breed. This situation would then caused lack of gene flow within the deep-water shrimps , and the emergence of new species that are genetically different (diverge) from one another
The shallow-water shrimp, on the other hand, experience minimal isolation due to the shallowness of water, and could still breed with one another. Thus, they experience a relatively lower reproductive isolation
(x-3)² = (x-3)(x-3)
= x² - 3x - 3x + 9
= x² - 6x + 9
