  • come in many different shapes and sizes. They can be as small as four feet (1 1/4 meters) long weighing just 100 pounds (45 kilograms), or as large as 30 feet (nine meters) long weighing up to 11,000 pounds (950 kilograms). All dolphins, including even the largest, can move quickly through the water, using paddle-shaped forelimbs called flippers to steer, dorsal fins on their backs to stay balanced, and powerful tail fins called flukes to move forward. Their torpedo-shaped bodies flow smoothly in the water, so they don't make many waves. They use their flippers to make sharp turns and sudden stops. All dolphins have blowholes on the tops of their heads. These mammals breathe through their blowholes. They have to go to the surface of the water to breathe. Each dolphin has just one blowhole.

      Dolphins can be in many different shapes and size. Each one has just one blowhole, they go to the surface of the water to breath. The tail of the dolphin is called fluke, their tail makes them swim really fast. Dolphins swim flow smoothly so that they don't make big waves in the water.

  • The oxygen that fish and other animals with gills use is bonded to hydrogen molecules and is dissolved in the water.

stages sleep

  • Stage 1This is the lightest stage of sleep, the transition phase, where you feel yourself drifting off. If you were to forget about the alarm clock and allow yourself to wake up naturally, Stage 1 sleep would be the last stage before you fully wake up. You don't spend too much time in Stage 1 sleep, typically five to 10 minutes, just enough to allow your body to slow down and your muscles to relax.

      The stage 1 of sleep is when you are starting to relax your muscles and start to sleep. This stages is not very long it is about 5 to ten minutes. This stage is when you wake up more quickly for example if someone touches you you will easily wake up.
  • Stage 2The second stage of sleep is still considered light sleep. Your brain activity starts to slow down, as well as your heart rate and breathing. Your body temperature falls a little and you're beginning to reach a state of total relaxation in preparation for the deeper sleep to come.
  • Stage 3Stage 3 sleep is the start of deep sleep, also known as slow wave sleep. During stage 3, your brain waves are slow "delta waves," although there may still be short bursts of faster of brain activity (also known as beta-waves). If you were to get awakened suddenly during this stage, you would be groggy and confused, and find it difficult to focus at first.

      this stage is when your body is finishing to relax and example is: if someone trys to wake you up you would be confused and do not know what is happening because you were already finishing to completely relax

  • Stage 4Of the five stages of sleep, this is the one when you experience your deepest sleep of the night. Your brain only shows delta-wave (slow wave) activity, and it's difficult to wake someone up when they're in Stage 4 of sleep.

      this stage i when you are more hardly to be awaken. In this stage is when you start to dream and this stage is when the kids start having nightmares
  • It's during Stage 4 sleep that children are most likely to suffer from bedwetting or sleep terrors. Stages 3 and 4 can last anywhere from 5 - 15 minutes each, but the first deep sleep of the night is more likely to be an hour or so. This is the time when the body does most of it's repair work and regeneration.
  • Stage 5 This is the stage of sleep when you dream. It is also referred to as "active sleep" or REM sleep, which stands for the rapid eye movements that characterize Stage 5. During REM sleep, your blood flow, breathing, and brain activity increases. An EEG would show that your brain is about as active as it is when you're awake.Another aspect of Stage 5 sleep is that the muscles in your arms and legs will go through periods of paralysis. Scientists speculate that this may be nature's way of protecting us from acting out our dreams.The first period of REM sleep of the night usually begins about 90 minutes after you start drifting off, and lasts for about 10 minutes. As the night passes, the periods of REM sleep become longer, with the final episode lasting an hour or so.Babies may spend as much as half of the time they're asleep in the REM phase. For a healthy adult, Stage 5 occurs for about 20 to 25% of the time you are sleeping, and decreases with age.Scientists and researchers are continually learning more about the mechanics and physiological effects of sleep, and what happens during the five stages of sleep.

      This stage is when you are completly relaxed and many babies are many time during this tage and adults are abaut 25% of they sleep

  • Your family may be like a dolphin family. Dolphins live in big family groups, called pods. As soon as a baby dolphin, or calf, is born, her mother and father push her to the surface of the water so that she can breathe. The calf stays by her mother's side most of the time, but her father, aunts, uncles, brothers, and sisters all help to take care of her.

      The Dolphin family is really similar to people family's. The group of Dolphin's are called pods. A baby Dolphin is named calf. When they are big enough, their parents push her/him into the surface. All the family takes care of the baby. By family I mean aunts, uncles, brothers, sisters and obviously their parents.

      Inside the fish theres something called the lamellae (The lamellae is an organ that the fish has to help it breathe.) and theres tiny blood cells and theres a blood vessel that bring the blood really close to the surface. When water goes into the gills,oxygen goes to the fish. When blood carries oxygen to the lamellae it doesn't have a lot of oxygen. Blood swims through the blood vessels and water swims the opposite way to the lamellae. That way, blood swims through the gills but it was a little less oxygen than the water around it. When the blood can't hold any more oxygen it swims its way to the heart.

      To get oxygen the fish just moves with their mouth open or take a gulp of water

      The bigger the lamellae is the better blood can hit contact with water and the fish can get more oxygen

      The lamellae has evolved so much to have the most surface area it can have
