How long could you stand on Antarctic ice before your bare feet froze solid? A minute. Maybe two? If you're an emperor penguin, you can do it for two months in cruel winds at as low as-75 degrees Fahrenheit, but their special circulation acts as a kind of antifreeze to keep them warm enough.
Penguin legs and feet have evolved to lose as little heat as possible. Penguin feet preserve heat by restricting blood flow in really cold weather, keeping foot temperature just above freezing.
Blood vessels to and from the feet are very narrow and woven closely together, cooling the blood from the body on the way to the feet and heating the blood as it returns to the body..
This special ability is part of how penguins keep their eggs warm until they hatch. Each penguin egg's father balances it on his feet and covers it with his very warm layer of feathered skin to keep it cozy while females are out feeding at sea.. If females haven't returned with food by time the chicks hatch, male penguins feed their babies for a few days on a kind of "milk" made from special cells inside their throats.
Your hands get whiter during freezing weather because there's less blood in them which has been redirected to the central part of your body to make sure vital organs stay warm.
A. Penguin legs work like a heat exchange system
B. Those naked bird feet may look extremely cold
C. Therefore, the male penguins must stay together in groups
D. However, parenting doesn't stop there for these devoted fathers
E. Emperor penguins also have the ability to 'recycle' their own body heat
F. Feet get cool blood so there's less heat to lose, while the body stays warm and comfortable
G. In fact. humans have the ability to restrict blood flow to their hands and feet in cold weather too
The cultures of the East and the West really distinguish each other a lot. {#blank#}1{#/blank#}
The origin of the eastern cultures is mainly from two countries: China and India. Both of the two cultures are developed by rivers—the Yellow River in China and the Hindu River in India. {#blank#}2{#/blank#}
When the two mother rivers gave birth to the Eastern culture, another famous culture was brought up on the Mesopotamian Plain-the Mesopotamian Civilization. This civilization later on developed into the cultures of Ancient Greece and Ancient Rome. {#blank#}3{#/blank#} Like the Chinese culture, the European culture also crossed waters. When the British settled down in America, their culture went with them over, the Atlantic Ocean. So the American culture doesn't distinguish from the European culture a lot.
{#blank#}4{#/blank#} Take the language system for example. In the East, most languages belong to the pictographic language while the Western languages are mostly based on the Latin system. Other causes like human race difference counts as well. But what's more, due to the far distance and the steep areas between the East and West, the two cultures seldom communicate until recent centuries. So they grew up totally in their own ways with almost no-interference (干扰)from the other.
The differences are everywhere. {#blank#}5{#/blank#} But different cultures make the world of 21st century more colorful. The cultural gap should not be the obstacle to the civilization of human being. It ought to be the motivation of our going farther.
A. Let us work together to keep a variety of culture. B. One important thing is to learn about other cultures. C. And these two are well-known as the base of the European culture. D. At the same time, some other differences add to the cultural differences. E. This is because the culture systems are two separate systems on the whole. F. They helped the two cultures develop for centuries and form their own styles. G. They are obvious and affect people's ways of thinking and their views of the world. |
