Fifth Grade Explanatory Essay 500 Words

I am a little bee. We bees live in colonies. There are three kinds of bees in a colony: a queen bee, a few males and thousands to tens of thousands of worker bees. I'm one of those tens of thousands of worker bees. My mother is the queen bee, and she's the largest of them all, almost incapable of flight. It doesn't matter, she has millions of children, so we can provide for her and do our duty! In my family, the queen bee is the only one who can lay eggs, and she can give birth to 15,000 to 20,000 brothers in a day and night. The life expectancy of the queen bee is about three to five years, so she is the longevity of our family. There is another bee in the colony, the male bee, which is very different from us: it is "big", with a thick body and long wings. His job is to mate with the queen bee. And after that, he's dead. We worker bees are the most numerous and responsible of the family. We are the main members of the colony and have the heaviest workload: collecting pollen and nectar, making our "food", nurturing our brothers, feeding our mothers, building our houses, protecting our homes, and regulating the temperature and humidity in our rooms. ...... Don't look at it like this, but we are very weak. Our bodies are very weak, and we live only six months, like shooting stars in the sky - a flash in the pan, with only a little time to shine. We bees are the hardest workers in nature. When the flowers are in bloom, we are so busy that we forget about morning and evening, and sometimes we even take advantage of the moonlight to collect flowers to make honey. Honey is very difficult to make. To make one kilogram of honey, we have to collect the raw material from one million flowers. If our hive is one and a half kilometers away from the flowers where we collect honey, then we have to fly 450,000 kilometers to collect one kilogram of honey, which is equivalent to 11 times around the earth's equator. It seems that our work is not inferior to that of the Apollo! Although it is difficult for us to collect honey, every year a colony of bees can cut dozens of pounds of honey. Our cousins in Guangdong are not idle all year round. If the animal world had an organization, we bees would be awarded the Medal of the Most Labor-loving. You may ask: How do you know what plants bloom and where they flow nectar in the boundless nature? To tell you the truth, we have a lot of "detectives", sent them to scout, and then come back to tell the results to their peers, our "language" is dance . Our family is like that. Our lives are short, but don't worry, we have brothers and successors. They will continue to work just like us. This is how our family continues to reproduce.

There are two types of camel camels, the dromedary with one hump and the bactrian camel with two humps. Dromedary camels are taller and can walk and run in the desert, carry cargo and pack people. Bactrian camels have short, stubby limbs and are better suited for walking on gravel and snow. Unlike other animals, camels are particularly resistant to hunger and thirst. People can ride a camel across the desert, so the camel has the name of "the boat of the desert". The camel's hump stores fat, which breaks down into the nutrients the camel's body needs to survive when it can't get food. Camels can go for four or five days without eating because of the fat in their humps. In addition, the camel's stomach has many small bottle-shaped bubbles, that is where the camel stores water, these "bottles" of water so that even if the camel does not drink water for a few days, there is no danger to the camel's life. The camel's ears have hairs, which can block the sand from entering; the camel has double eyelids and thick long eyelashes, which can prevent the sand from entering the eyes; the camel's nose can also be closed freely. These "equipment" make the camel is not afraid of the sand. The sand is soft, human feet step on it is easy to fall into, but the camel's paws flat, under the foot of a thick and soft cushion of flesh, such paws so that the camel in the sand walking freely, will not fall into the sand. The camel's fur is so thick that in winter, when the desert is very cold, the camel's fur is extremely powerful in keeping its body temperature up. The camel is familiar with the desert climate and will kneel down when a gale is about to strike, so that the traveler can be prepared in advance. The camel walks slowly, but can carry a lot of things. He is an important means of transportation in the desert, people see it as a boat across the desert sea, there is a "desert boat" reputation. It lived in North America 10 million years ago, and its distant ancestors crossed the Bering Strait to Asia and Africa, and evolved into the Bactrian camel and the human domesticated dromedary. The hump of a Bactrian camel can store up to 40 kilograms of fat, which breaks down into the nutrients and water the camel needs when it is hot and dehydrated. Camels can drink more than 100 liters of water in 10 minutes, while the drainage is small, only about a liter of urine in the summer day, and they only begin to sweat when their body temperature is about 40 degrees, and do not easily open their mouths, which makes the camel can stick in the desert for 8 days without drinking water will not die of thirst. In addition, when mammals lose too much water in their bodies, they need to extract water from their own blood to replenish it, but this will cause the blood to thicken and lead to a reduction in the speed of circulation, metabolic dysfunction and heatstroke. Camels, on the other hand, balance this with water in their muscles. Camels have broad pads of flesh on their feet and walk with toes splayed to ensure that they can walk in the desert without sinking into the sand. They have long eyelashes, nostrils that open and close automatically, and ears covered with dense hair, all of which protect them from the wind and sand. Bactrian camels mate in January and February, while dromedaries mate during the rainy season, when males become aggressive. The gestation period is 12 months for dromedaries and 13 months for bactrian camels, with a lactation period of 3-4 months. Young camels are born strong and can follow their mothers around in a day. Bactrian camels like to form small herds and can eat any plant, migrating north and south of their range in spring and fall. Wild camels are very rare and are classified as national protected animals.
