WHAT ARE THESE?
Ants are eusocial insects, i.e. They have the highest level of organization of animal
sociality, belonging from the family Formicidae and, like the wasps and bees, belong to
the order Hymenoptera, the third largest order of insects. Ants evolved from wasp-like
ancestors in the mid-Cretaceous period between 110 and 130 million years ago and
diversified after the rise of flowering plants. More than 12,500 of an estimated total of
22,000 species have been classified. What distinguishes them are their elbowed antennae
and the node-like structure that forms their slender waists.
HOW DO THEY LIVE AND FUNCTION “EUSOCIALLY”?
Ants form colonies that range in size from a few dozen predatory individuals living in
small natural

Ants have a distinct morphology- elbowed antennae, metapleural glands, and a strong
constriction of their second abdominal segment into a node-like petiole. the three distinct
body segments are- The head, mesosoma, and metasoma. The petiole forms a narrow
waist between the mesosoma (thorax plus the first abdominal segment, which is fused to
it) and gaster (abdomen less the abdominal segments in the petiole). The petiole may be
formed by one or two nodes (the second alone, or the second and third abdominal
segments)1
Like other insects, ants have an external covering that provides a protective casing around
the body and a point of attachment for muscles. oxygen and other gases, such as carbon
dioxide, pass through their exoskeleton via tiny valves called spiracles. they have a long,
thin, perforated tube along the top of the body (called the "dorsal aorta") that functions
like a heart, and pumps haemolymph toward the head, thus driving the circulation of the
internal fluids. The nervous system consists of a ventral nerve cord that runs the length of
the body, with several ganglia and branches along the way reaching into the extremities
of the appendages.

Mary Cowhey’s Black Ants and Buddhists, explains how to implement a Multicultural Education into the primary grades. Her pedagogy encourages educators to take a step back from curriculum demands, and a step toward teaching children to think critically in the “organic happenings of life in the classroom” (Charney). This book is written in a memoir-like fashion to convey what a classroom looks like when students are encouraged to speak their mind, engage with their community, and learn through rich experiences.
The inspiring documentary film, E.O. Wilson—Of Ants and Men, showcases biologist Edward Osborne Wilson’s passion for preserving the biodiversity of our natural world. E.O. Wilson not only values the fascinating creatures (particularly ants) that he comes across during his research and in his daily life, but he also takes action and participates in the Gorongosa Restoration Project at Gorongosa National Park in Mozambique, Africa. The destruction of Gorongosa demonstrates the call for us—Homo sapiens—to realize how critical it is to concern ourselves with protecting the very ecosystems that have molded us into the complex species that we are; according to E.O. Wilson, “We adapted over millions of years to wild environments…We really need them” (CITE?). The better effort we make to understand that we are a part of this large, interdependent ecological community, the better equipped we become in not only being

Nature can be murderous. Yet, thousands of people can go down trying to fight it. Which almost happened in the story “Leiningen Versus the Ants” by Carl Stephenson. Brazilian army ants are the main antagonists in the story, that represent nature. When humans are forced into conflicts with nature, the struggle will be intense and unpredictable, as a result of this the person will fail because nature has the ability to adapt and outwit. approaching the profound bloodshed, Leiningen had a calm attitude to the army ants, in view of his attitude, it leads to his downfall.
The Structure and Functions of the Arteries Arteries are blood vessels that convey blood from the heart to the tissues of the body. The arteries expand and then constrict with each beat of the heart, a rhythmic movement that may be felt as the pulse. Arteries are usually named from the part of the body that they are found, for example; brachial artery found in the arms, metacarpal artery found in the wrist; or from the organ which they supply as the hepatic artery supplies the liver, pulmonary artery brings deoxygenated blood the lungs. The facial artery is the branch of the external carotid artery that passes up over the lower jaw and supplies the superficial portion of the face; the haemorrhoidal arteries are three vessels that supply the lower end of the rectum; the intercostal arteries are the arteries that supply the space between the ribs; the lingual artery is the branch of the external carotid artery that supplies the tongue. The structure of the artery enables it to perform its function more efficiently.
The human nervous system is divided into two parts, the central nervous system and the peripheral nervous system. The central nervous system, CNS, is just the brain and spinal cord. The peripheral nervous system, PNS, includes the nerves and neurons that extend outwards from the CNS, to transmit information to your limbs and organs, for example. Communication between your cells is extremely important, neurons are the messengers that relay information to and from your brain. Nerve cells generate electrical signals to transmit information.
The lymphatic system is very similar, and works with and directly at the side of the cardiovascular system. The lymphatic system has a network of vessels like the circulatory system which pump a plasma-like fluid called lymph around it’s own lymph vessels, and are found in most other tissues of the body, except the central nervous system.
The heart serves as a powerful function in the human body through two main jobs. It pumps oxygen-rich blood throughout the body and “blood vessels called coronary arteries that carry oxygenated blood straight into the heart muscle” (Katzenstein and Pinã, 2). There are four chambers and valves inside the heart that “help regulate the flow of blood as it travels through the heart’s chambers and out to the lungs and body” (Katzenstein Pinã, 2). Within the heart there is the upper chamber known as the atrium (atria) and the lower chamber known as the ventricles. “The atrium receive blood from the lu...
Fighting off a few million ants is not easy when they will eat you alive if you get in their way. In “Leiningen Versus the Ants,” Leiningen, originally a self-assured, courageous, and stern plantation owner, changes drastically after his deadly encounter with a caboodle of ants to become a boastful and yet still, courageous survivor.
Leiningen Versus the Ants tells the tale of a wiry old planter, Leiningen, and his fight to protect his plantation and workers against an army of millions of deadly Brazilian ants. The protagonist, a man of strong constitution and a brilliantly sharp mind, demonstrates remarkable tenacity when placed up against his foe. Throughout the story, he shows traits that enable his resolution of the conflict, including stubbornness, intelligence, courage, and physical strength.
Arthropods have an open circulatory system, in which blood is pumped through a tubelike heart and out into the body cavity. In comparison, vertebrates have a closed circulatory system, in which blood is contained inside a system of arteries, veins, capillaries, and a heart. In an open circulatory system, blood is pumped through the heart and into the body, where it comes in direct contact with organs and tissues. The stiff exoskeleton of arthropods also helps control blood pressure. Because an exoskeleton does not change shape, when the heart pumps blood out into the body, the exoskeleton keeps the blood contained, while body movements keep it
The water vascular system of echinoderms is a hydraulic system that they use for respiration, getting rid of waste, and a way of movement. This special system is made up of different canals that connect to various tube feet. It is activated by a calcareous plate called the madreporite. The madreporite is located on the aboral surface and takes in water to restore the whole system. The canals in this structure restrict what particles enter and the cilia are what catch the particles that are flushed back into the ocean. When water enters into an echinoderm, it goes through the radical canal and then into the lateral branches that are attached to the tube feet. For the tube feet to be able to move, the pressure created by the ampulla needs to occur. When this valve is closed the tube feet are able to stretch and when it is opened, pressure is released and the tube feet are able to come back in.
Ants have four growing stages, the egg, larva, pupa, and the adult. There are over 100,000 known species of ants. Each ant colony has at least one or more queens. The queens job is to lay eggs. How did she start her colony?
Insect, small, air-breathing animal characterized by a segmented body with three main parts—head, thorax, and abdomen. In their adult forms, insects typically have three pairs of legs, one pair of antennae, and in most instances, two pairs of wings. Insects rank among the most successful animals on Earth. About one million species of insects have been identified so far, which is about half of all the animals known to science. That is why for every pound of human on the earth there are 10 pounds of insects. So that is why there are many reasons why insects are so successful, their exoskeleton, their size, their body function, the way they reproduce, and their development of metamorphosis.
Male ants are winged as well, their sole purpose is to mate with the queens.
