Question

Please answer two questions. These are two topics my classmates talked about in class, I want you to compare and contrast and write what is interesting in them

first topic: comparison of locomotive patterns between seals and flying birds based on muscular outputs.

second topic: comparison of the physiology of camouflage in octopus and chameleons

Compare and contrast and write something interesting about them in EXACTLY 250 words

Answer 1

First topic: the comparison of locomotive patterns between seals and flying birds based on muscular outputs.As flying birds generally used the flapping and gliding movements to reduce the mechanical requirements of level flight while undergoing cyclical changes in flight attitude known as undulating flight. Seal shows intermittent gliding movements interspersed with power locomotion to reduce mechanical force on horizontal motion.

Second topic: The octopus is sometimes called as chameleons of the sea. The octopus belongs to cephalopods and octopus also can change colour and appearance to attract the mate or send a warning message. The warning message is send so that prey is away from predator. Ocotopus can do this as it consists of chromatophores under the skin and using the combination of muscles, nerves and pigments the animal manipulate their chromatophores to exchange their external appearance The colour change is totally dependent on neuronal activation. As the brain send the signal the colour change ripples through the animal's body. On the other hand chameleons changes their colour gradually. It takes only few minutes to change its whole transformation and may be called as a chameleons jungle octopuses or dirt squids.
