Taste buds
Taste buds are actually very interesting. Taste buds are sensory organs that are found on your tongue and allow you to experience tastes that are sweet, salty, sour, and bitter.Taste buds have very sensitive hairs on them called microvilla. These tiny hairs are what makes you taste. They send signals to your brain telling it if its sweet, sour, salty etc. The average person has about 10,000 taste buds and they're replaced every 2 weeks or so but they decrease as you get older that's why certain foods may taste stronger to you than they do to adults. Smoking also can reduce the number of taste buds a person has. Taste buds are very interesting.
Slugs
Believe it or not slug's slime has a purpose. They use it to suction power and to travel upside down and up trees and other vertical surfaces. They leave a slime trail behind them as they move. When in danger the slug will let out a thick mucus coating and make their body shorter and fatter. This makes it difficult to eat them and gives them a coating with an unpleasant taste to potential predators. Slugs can fit into almost any space due to their ability to become very long and thin or short and fat. Their slime helps them fit through tight areas. They can avoid sunlight by crawling into small crevices and holes. Their slime also helps keep water in their bodies an important factor in their survival. Slugs actually are very interesting.
Woolly Mammoth
A baby woolly mammoth which spent 40,000 years frozen in the Siberian permafrost, has provided scientists with clues about how the species survived during the Ice. Age"Lyuba" was sucked to her death in a muddy river bed. She was so well preserved that traces of her mother's milk remained in her belly when she was discovered three years ago by nomadic reindeer herders. Lyuba who was about a month old when she died has already taught researchers much about mammoths that they had been unable to gain from fossils. They have learned so much just from this baby that they expect to have the knowledge to be able to clone these incredible animals by the year 2015
The water cycle
The water cycle, also known as the hydrologic cycle or H2O cycle, describes the continuous movement of water on, above and below the surface of the Earth. Water can change states among liquid, vapor, and solid at various places in the water cycle. The water cycle is probably one of the most important cycles there are.If there was no such thing as the water cycle,if the water had no way of getting from the ground to the clouds then there probably wound not be an earth as we know it.
carnivore
A carnivore is an animal that eats a diet consisting mainly of meat, whether it comes from live animals or dead one An omnivore is an animal that eats both plants and meat. A herbivore is often defined as any organism that eats only plants. By that definition, many fungi, some bacteria, many animals,vores lack the specialist behaviour of carnivores and herbivores. These three groups pretty make up our food chain. If it was not for these groups our world would be very different from how we know it today.
140 new relatives to our world!
in the year of 2011, researchers at the California Academy of Sciences added 140 new relatives to our world. The new species include 72 arthropods, 31 sea slugs, 13 fishes, 11 plants, nine sponges, three corals, and one reptile. This just goes to show that there are still plenty of places to explore and things to discover on Earth. These creatures were found all over the world. People had to go through great lenghts to find these. They went to six continents (all except Antarctica) and three oceans (Atlantic, Pacific, and Indian), to find them. This is important to our society because it lets us know more about the world we live on.
Wasps
Well-preserved fossil insect cocoons have allowed researchers in Argentina to describe how wasps bred in rotting dinosaur eggs. In 1989 scientists found the 70-million-year-old titanosaur eggs in southern Argentina, an area well known for fossils and dinosaur eggs They later saw that some of the broken eggs they found contained fossilized insect cocoons that were similar in size and shape to the cocoons of certain modern day wasps. There are many records of dinosaur eggs, and even several records of fossil cocoons. But author Jorge Genise says that "this is the first time that these cocoons are found closely associated with an egg." The results indicate that wasps probably participated in the food web, mostly composed of scavenging insects, which developed in the rotten egg. This is important to our knowledge because it gives us a better understanding on the world before humans.
Low-Fat Yogurt
A recent study showed that if pregnant mothers eat low-fat yogurt it can increase the risk of their children developing asthma and allergic rhinitis such as (hay fever). The reason that this was even found was scientists study was aimed to assess whether fatty acids found in dairy products could protect against the development of allergic diseases in children. They then found out that milk and dairy intake during pregnancy have monitored the prevalence of asthma and allergic rhinitis. The reason i have chosen this article is because i think it is very important to all pregnant mothers out there. This can help our world because if these rules were fallowed then it will decrease all the asthma kids.

Energy cycle
Energy is one of the most important things on this earth. There would not be any living creatures anywhere if there was no energy.The sun is the energy source of all life on our earth. Every form of energy, except for atomic energy, can be traced back to the sun. Luckily the earth is at the perfect distance from the sun for the it to heat and provide energy for human life. The cycle starts with plants.The suns energy it gives off is stored by plants who are the primary producers in ecosystems. When the herbivores come around and eat the energy filled plants the energy is now passed on to that animal. Eventually when that animal dies or gets eaten the energy is passed on again. This cycle is extremely important because it gives us life! If it was not for this cycle we would not have plants, animals,and most importantly humans.

spider brains
Reaserch shows that the brains of tiny spiders are so large that they fill their body cavities and overflow into their legs. The STRI discovered that the central nervous systems of the smallest spiders fill up almost 80 percent of their total body cavity, including about 25 percent of their legs. in some species of spiders the smaller the spider the more bulgy there body is. This is like that because there is so much excess brain in there bodies. Spiders are acually very smart for there size. They need a lot of brains to be able to web those complicated webs.
Spider plant
Spider plant are very popular mostly because they are one of the easiest plants to grow. These plants usually grow naturaly in certine areas. It is native to tropical and southern African climates. Spider plants are cool because they are herbaceous perennial which means they grow all year around. The average hight of these plants are around 60 cm(24in). Spider plants prefer bright light, and tend toward scorching in direct sunlight. However, they will grow in conditions ranging from semi-shady to partial direct sun. These plants will have a hard time growing in 50 deg. or below. Spider plants are a big help to our world because they are very easy to grow and they produce a steady sorce of oxygen for us.

Food Chain
The Food chain is a very interesting system. Basically what it is, is a system that puts all animals and plants into a less to greatest spot. It starts out as a decomposers that are not big enough to eat other things other then bacteria and things like that. Then it goes to producers that eat the decomposers and everything it excreats. A lot of animals are in between but it is bascally just animals and what eats thos animals to survive.

oil spill
The Oil Spill in the Mexico Gulf has been a terrible incident. On April 20, 2010 an oil rig working for a company called BP struck an oil pocket about one mile under the surface of the ocean. This coused millions of gallons of oil to pour out and leak into the ocean. As soon as possible they got a clean up crew down there and started to capture som of the oil that was rising to the surface. At first they didnt make much of it they thought it wasnt going to be such a big deal but they were wrong. As of the 27th of september it has oozed more then five times the guessed amount. as a result of all of this hundreds of animals that made there homes anywhere near the spill have died or had to find new homes. The oil spill has gotten better but it is still hard to know for a fact when its going to stop.

Cancer
Cells are a very important part of your body. They pretty much controll everything even cancer.
Cancer grows out of normal cells in the body. Normal cells multiply when the body needs them, and die when the body doesn't need them. Cancer appears to occur when the growth of cells in the body is out of control and cells divide too quickly. It can also occur when cells forget how to die. So if you have a surplus of cells you have the chance of getting cancer. Depending on what kind of cancer it is depends on what the cause it is.

Genetics is a big part of biology. Genetics allow us to understand why some humans have some traits and others dont. Such as blue eyes or different color hair. Genetic traits come from past generations. You usally have simular properties as your parents or grandparents. If both of your parents have brown hair it means there is a very high probably that you will have brown hair. Another thing that genetics helps us with is crossbreading. When people crossbread anything from plants to animals they need to intake the possibilities of genetics.
Anatomy
Biology is very interesting! what makes it so interesting is that there is so many different kinds and types of biology. There is Cell biology, Astrobiology, Genetics and many many more. But the one type that really stood out to me and made me interestsed is Anatomy. Anatomy is baseically the study of how things work. Mainly animals and the human body. This allows us to figure out and comprehend how the human body works and what body parts does what. Without this particular type of biology we would be lost in the world. If we did not have Anatomy there would be a lot less population because it allows us to find out what is acually arong with you when your sick. A lot of people would die for things we now think is no big deal.
