Dental Health

People begin to learn about dental health from a very young age, when teeth first begin to show up. But in spite of such early awareness, many people fail to maintain good dental health through their adult life. Good dental health comprises brushing and flossing your teeth every day, and regular visits to a dentist or dental hygienist as well. Besides, people supplement their dental care with the use of products like mouthwash or advanced mouth care systems. You should keep it in mind that the lack of adequate dental care practices will result in cavities and gum disease.

It is generally advised that you use a toothbrush with softer bristles so as to protect your gum. Some people, however, prefer power brush systems that help break up plaque and bacteria in your mouth. But it takes more than brushing to keep your teeth in good health. Some other steps need to be taken to ensure that people do not lose their teeth as they become old.

Cervical Cancer

One type of cancer is a scourge for the Eve is cervical cancer or cervical cancer. This cancer is a disease of the second most common cancer worldwide are common in women over the age of 15 years.
In fact, the world's approximately 500 thousand women diagnosed with cervical cancer and an average of 270,000 deaths annually, or in other words, every two minutes a woman died of cervical cancer.
While in Asia, cervical cancer is cancer in both women suffered the most, and more than half of Asian women who have died of cervical cancer. This is equivalent to 226 thousand women are diagnosed with cervical cancer and as many as 143 thousand causes of death, or in other words every 4 minutes, a woman in Asia Pacific, died of cervical cancer.

Cause of Cervical Cancer
Generally, cervical cancer began to attack from the cervix (part of the uterus or womb) and then reach the vagina. This cancer will spread gradually if not detected early and given treatment. So what causes cervical cancer? The most common cause is a virus HPV (human papillomavirus). There are 100 types of HPV viruses were identified and most are harmless and do not show symptoms. A total of 40 types of HPV can be transmitted through sexual contact.

Mesothelioma Cancer

 When a patient learns of a mesothelioma diagnosis, confusion is often one of the first emotions experienced. What exactly is mesothelioma? Is it a disease? A virus? Mesothelioma is actually a rare type of cancer. When people refer to mesothelioma disease, they are actually referring to mesothelioma cancer. Mesothelioma develops in the mesothelium, the membrane that surrounds several body cavities. The mesothelium is comprised of mesothelial cells, which become abnormal and divide uncontrollably if mesothelioma is present.

Four different types of mesothelioma exist. Pleural mesothelioma is the most common form of the cancer and develops in the lining of the lungs, known as the pleura. Peritoneal mesothelioma affects the lining of the abdomen, known as the peritoneum. Pericardial mesothelioma is very rare, as approximately 200 cases have been reported internationally. Pericardial mesothelioma develops in the pericardium, the membrane that surrounds the heart and protects the organ. Testicular mesothelioma is the rarest form of mesothelioma and develops in the lining surrounding the testicles, known as the tunica vaginalis.

 The bee is a large group of insects known for his gregarious although not all bees are so. All the bees go in the tribe / family Apidae (order Hymenoptera: winged insect membranes). In the world there are approximately 20 000 species of bees and can be found on every continent, except Antarctica.

Female insects have an important role in this insect group. The behavior of bees is largely determined by the behavior of female bees. Some females of certain species of bees live alone (solitary) and others are known to have a social behavior. Solitary bees build their own nest and foraging for offspring without the help of other bees and usually die or leave the nest at the time offspring not become adult bees. Sometimes a few species of solitary bees to feed and care for their children without giving up food for their children, form a relationship like this is known as sub social. While on a higher stage, bees live in groups and share duties in accordance with their respective physical form.

Ants are insects that come from a family eusosial Formisidae, and ants are included in the order Himenoptera along with bees and wasps. Ants are divided into more than 12,000 groups, with a large number of comparisons in the tropics. Ants are known to nest-nest colonies and orderly, which sometimes consist of thousands of ants per colony. Types of ants are divided into worker ants, ant males, and the queen ant. One colony may retain and use a large area to support their activities. Ant colonies are sometimes called superorganisme because the colony appears to operate as a unity.
Ant's body, like other insects, have exoskeleton or external skeleton that provides protection and also as a place of attachment of muscles, unlike the human skeleton and vertebrate animals. Insects have no lungs, but they have breathing holes called spiracles in the chest for air circulation in the nervous system. System ant respiration consists of a ventral nerve kind of muscle that lie along the body, with some fruit and branches of the ganglion associated with each part in the body.

Blue-Ringed Octopus
The octopus is a cephalopod  of the order Octopoda. Octopuses have two eyes and four pairs of arms and like other cephalopods are bilaterally symmetric. An octopus has a hard beak, with its mouth at the center point of the arms. Most octopuses have no internal or external skeleton, allowing them to squeeze through tight places. Octopuses are highly intelligent, probably the most intelligent of all invertebrates.

The octopus inhabits many diverse regions of the ocean, especially coral reefs. For defense against predators, they hide, flee quickly, expel ink, or use color-changing camouflage. An octopus trails its eight arms behind it as it swims. All octopuses are venomous, but only the small blue-ringed octopuses are deadly to humans.

Metamorphosis in insects is often followed by destroying in tissues at larval phase is replaced by networks of cells that have differentiated new. Insect molting to grow in a way that is new cuticle growth with increasing body size. There are three types of growth in the Insecta:
  1. Ametabola, the stage is not the larval stage, the moth and sample like a fleas. 
  2. Hemimetabola, namely through the stages of metamorphosis pro-nimpha which occurred just after hatching. After that, the insects have nimpha stage. In hemimetabola metamorphosis, the wing rudiment, genital organs, and the structure characteristics of the other developments already formed but not yet perfect. However, these organs grow perfectly at the end of molting. An example can be found in locusts and vermin.  
  3. Holometabola, the metamorphosis that began with process larvae after hatching. Undergoing molting larvae will grow and large. Stages of suffering among larvae instar called molting. After the final instar stage formed pupa. During the formation of the pupa, there was the formation of adult structures.
Hormones that affect the metamorphosis of butterflies - butterfly Molting and metamorphosis are controlled by several effectors such as hormones, namely: Read More Here

Metamorphosis is a biological process by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body  structure through cell growth and differentiation. Some insects, amphibians, mollusks, crustaceans, Cnidarians, echinoderms  and tunicates  undergo metamorphosis, which is usually (but not always) accompanied by a change of habitat or behavior.

Scientific usage of the term is exclusive, and is not applied to general aspects of cell growth, including rapid growth spurts. References to "metamorphosis" in mammals are imprecise and only colloquial, but historically idealist ideas of transformation and monadology, as in Goethe's Metamorphosis of Plants, influenced the development of ideas of evolution.

Insect  growth and metamorphosis are controlled by hormones  synthesized by endocrine glands near the front of the body.

Single Cell

Living things is the simplest single-celled organisms. They were the first living creatures on earth, and until now still in the meet everywhere.

Cell is the smallest part of the life-support units. Living things are the simplest has only one cell, which contains all the information and processes necessary for survival and reproduction of such cells.

Cell has a thin outer wall, which can penetrate through which chemical substances. In the cell walls are jam-like fluid called the cytoplasm, which contains small structures or small organs, often called organelles, to perform specific functions. The structure is the central nucleus, which contains genes that determine cell shape and function. The rest are other structures releasing energy from food, remove the remaining substances, or protect the cells from other organisms attack.

More than 3000 million years ago, single-celled organisms first appeared in the waters of the earth. Chemical elements that make the creation of life is unknown. Now the simplest living things are classified in the Monera. There are two main groups, namely bacteria and cyanobacteria (algae green / blue algae). Its size is very small so can only be seen through a microscope with strong magnification.

Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis.
Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant.

Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis.
Chloroplasts are one of the many unique cells in the body, and are generally considered to have originated as endosymbiotic cyanobacteria.
In this respect they are similar to mitochondria, but are found only in plants and Protista.

A microorganism or microbe is an organism that is microscopic. The study of microorganism is called microbiology, a subject that began with Anton Van Leeuwenhoek’s discovery of microorganism in 1675, he using a microscope of his own design.

Microorganism are very diverse. They include bacteria, fungi, and protist. Micsroscopic plants or green algae, and animals such as plankton and the planarian. Some microbiologist are include viruses, but others consider these as non-living.

Most microorganism are unicellular (single-celled), but this is not universal, since some multicellular organism are microscopic, while some unicellular protists and bacteria, are macroscopic and visible to look with naked eye.
