Chameleon information.

Chameleons are reptiles whose scientific name is evasion. Mainly found on the African continent and Madagascar, it is a very peculiar animal with various characteristics and behaviors that are suitable for arboreal life.

It is about 25 centimeters long, with a flattened body on its sides, a spine on its back, and a blunt triangular protrusion on the occipital part of its head. The limbs are very long, and the fingers and toes are combined and divided into two opposite groups, the first three fingers of the forelimbs form the inner group, and the fourth and fifth fingers form the outer group; Hind limb.

The first and second toes form the inner group, and the peculiar three toes form the outer group, which is very suitable for holding branches. It has a long tail and can wrap around branches. It has a long, sensitive tongue that sticks out longer than its body length, and glands on the tip of the tongue that secrete a lot of mucus to stick to insects.

It has a pair of eyes that are very peculiar, the eyelids are very thick, ring-shaped, the two eyeballs are protruding, 180 degrees from side to side, and they can rotate freely up and down, left and right, and the left and right eyes can move separately and are not coordinated, which is rare in animals. The eyes are divided into different parts of the labor to look forward and backward, which is not only conducive to predation, but also can detect the enemy behind in time. Chameleons hunt with long tongues that are lightning and take only 1 25 seconds to complete.

Chameleon, also known as evasion, "service" in Chinese characters means "things that need to be contributed", and the meaning of avoidance means that you can eat food without exerting your strength. Hence the name of the refuge.

Commonly known as a chameleon, it is good at changing the color of its body at any time with changes in the environment. The discoloration is good for both hiding oneself and catching prey. Discoloration is a physiological change that is accomplished through the expansion or contraction of pigment cells in ** under the regulation of the autonomic nervous system.

1. With the rapid growth of population and the development of productive forces, the rapid development of science and technology, and the continuous increase of industrial and domestic wastes, the air, water quality, and soil pollution are becoming more and more serious, the natural ecological balance has been violently impacted and destroyed, and many resources are decreasing day by day, and they are facing the danger of depletion; Soil erosion, land desertification is also becoming more and more serious, food production and human health are seriously threatened, therefore, maintaining ecological balance and protecting the environment is a fundamental issue related to human survival and social development.

Second, China's environmental protection value chain has a prominent position in the entire national economy, but the problem of environmental pollution in the development of national economic construction is not slackened and despised; It is an urgent task to improve environmental protection policies so as to better manage and respond to environmental emergencies.

3. Conservation of biodiversityForests themselves are not only primary producers, but also provide a wide variety of food resources and habitats for consumers at all levels. Thanks to the unique and superior living environment of the forest, all kinds of animals and plants can reproduce, preserve and thrive. As a result, forests are home to a large number of biological species, especially rare flora and fauna.

The destruction and disappearance of forest ecosystems can have devastating consequences for biodiversity. Therefore, to a certain extent, the existence of forest ecosystems and their diversity play a decisive role in biodiversity conservation.

Fourth, with the development of China's economy, the effective use of energy, the reduction of environmental pollution, the reduction of the frequency of production safety accidents, the prevention of environmental emergencies, and the importance of ensuring life safety have become increasingly prominent. The formulation and implementation of environmental protection policies and measures to improve the quality of life of the people while protecting the environment has become the focus of China's livelihood projects. Protecting the environment is not only about people's living environment, but also affects economic development.

5. Environmental FunctionsForests are the tallest green plants on the earth, an important part of the earth's ecological balance, and an important factor in regulating the global water cycle and carbon cycle, with irreplaceable functions. It is mainly manifested in regulating the climate, purifying the atmosphere, conserving water sources, maintaining water and soil, preventing wind and fixing sand, etc.

Because there is only one earth, if we don't protect her, our home will not be safe, such as: sandstorms, **, mudslides, etc., are all caused by not protecting nature, so protecting nature is to protect ourselves!

Because nature is like our mother, who cares for our growth every day and every night, so that we do not suffer disasters and lead to death; Fill the world with weeping and death.

Kiss! Human beings protect nature is a long-term and arduous task, and the following are some methods and measures to protect nature:1

Reduce pollution: Humans should reduce pollution of the natural environment, including air, water, and soil pollution. This can be achieved by saving energy, reducing waste, using environmentally friendly products, etc.

2.Wildlife conservation: Humans should minimize the destruction and killing of wildlife.

To this end, wildlife can be protected by establishing nature reserves, prohibiting poaching, and restricting the development of shelters. 3.Promoting sustainable development:

Humanity should promote the concept of sustainable development, that is, to meet the needs of the present without destroying the living environment of future generations. This can be achieved through the use of renewable energy, the promotion of a circular economy, and the promotion of green mobility. 4.

Protect water resources: Water is a necessity for human survival, and we should try to reduce pollution and waste of water resources. This can be achieved by strengthening water resources management and promoting awareness of water resource protection.

5.Protecting natural landscapes: Natural landscapes are an important part of human cultural and spiritual life, and the original appearance and uniqueness of natural landscapes should be protected as much as possible.

This can be achieved through the establishment of natural parks, the promotion of ecotourism, etc. Human beings need to start from many aspects to protect nature, and we need to work together to take effective measures to protect our common home.

Spring Breeze Dance.

The clear stream water is flowing quietly.

Fragrant flowers are quietly blooming.

Beautiful birds are singing happily.

They are singing about the sun tomorrow being more brilliant.

The spring breeze awakens every inch of the sleeping earth.

The spring rain moistened every silent face.

The growing grass looks forward to rain, dew and sunshine.

The stretched heart is pregnant with enthusiasm and unrestrainedness.

Sui Sui went to the clouds and came again.

There are always butterflies flying with flowers every year.

The spring breeze danced happily again.

Following its pulse, we jumped fast.

The awakening mood is bathed in the light of spring.

The memories of winter make it melt away from the snow.

The spring breeze danced happily again.

Following its pulse, we jumped fast.

The lotus flower comes out of the mud and is not stained, so du is telling us to clean ourselves up. The sea is a vast ocean, which is telling us that the open-minded version should be broad.

The tall Xiang Quan Sunflower holds his head high, which is teaching us to pursue.

The dull fool dares to move mountains, which is teaching us perseverance.

The plum as white as snow stands in the wind, which is teaching us to be brave.

The golden sunflowers face the sun, which is teaching us to go up.

A swarm of ants can carry away big bones, and that's teaching us unity.

Gentle droplets of water can drip through rocks, and that teaches us tenacity.

The grass silently retracted the leaves, which told us not to stretch the field too much.

Bees are busy shuttling among the flowers, which teaches us to be industrious.

Flea bai's jumping skills are very good.

Inspired by its vertical take-off and jumping methods, the aircraft manufacturing company has successfully built a Harrier that can take off and land almost vertically. Modern TV technology has created a large-screen color TV according to the structural characteristics of insects' single compound eyes, and can form a large screen of small color TV phosphor screens, and can frame several specific small pictures at any position on the same screen, which can not only broadcast the same picture, but also broadcast different pictures. According to the structural characteristics of the insect compound eye, scientists have successfully developed a multi-aperture optical system device, which is easier to search for the target, and has been applied in some important foreign systems.

According to the principle of mutual inhibition between the monoculars of the compound eye of some aquatic insects, the electronic model of side suppression made is used in various photographic systems, and the image can enhance the edge contrast and highlight the contour of the image, and can also be used to improve the display sensitivity of the radar, and can also be used for the pre-processing of text and recognition systems. The United States has developed an engineering model of the terminal guidance seeker of the insect compound eye homing with great practical value by using the principle of processing information and directional navigation of insect compound eyes. Japan has developed new construction methods for engineering machines and buildings such as hexapod robots using the morphology and characteristics of insects.

If you want to protect nature, you need to start from me, first of all, when we are outside, we don't litter, don't litter melon and fruit dander, and at the same time, we don't use disposable bags, disposable chopsticks and other disposable items, we need to use some easily degradable items, which is conducive to the development of nature, and at the same time we can plant trees every year, or do public welfare.

1. Save electricity and turn off the lights. 2. Save water, close the faucet, and don't waste or pollute water resources. 3. Don't litter when you go out. 4. Trees can be planted once a year. 5. Refuse leather products, do not kill animals and destroy plants.

How can we protect the environment?

Answer: If we want to protect the grassland, we must first fully understand the importance and urgency of strengthening the protection and construction of the grassland; Establish and improve the grassland protection system, and establish a basic grassland protection system. Grasslands with special ecological functions, such as artificial grasslands, improved grasslands, important grazing grounds, mowing grasslands, and grassland nature reserves, shall be designated as basic grasslands, and a strict protection system shall be implemented. No unit or individual may requisition, occupy or change the use of basic grassland without authorization.

Implement a grass-livestock balance system.

Secondly, according to the amount of forage provided by the grassland in the region in a certain period, the amount of livestock feeding should be determined, and the grass-livestock balance should be implemented. Stabilize and improve the production capacity of grasslands, strengthen the construction of grassland infrastructure focusing on fencing and water conservancy in pastoral areas, speed up the management of degraded grasslands, and improve disaster prevention and mitigation capabilities. adhere to the principle of "prevention first, prevention and treatment combined", and do a good job in grassland disaster prevention and mitigation; It is necessary to return reclaimed grassland to grassland, clarify the scope and key areas of returning farmland to grassland, and improve and implement various policies and measures for returning farmland to grassland.
