Nevertheless, the search for life on Mars continues, in part because it shows signs of having been wetter in the past. Water is necessary for all known forms of life. It is possible that microscopic life once existed on Mars. Today the surface is too cold and the air is too thin for liquid water to exist there for long. It is also bombarded with ultraviolet radiation from the Sun, which is very harmful to living things.

The earth is divided in 24 time zones. Time zones go north south pole to north pole, they are meridians, They are 360 that are degrees. Thats why they are different times. They are the same minute but different hour to the west of it and highest hour to the east. Smaller goes to west and bigger to east. The earth rotates. Thats why the hour changes. Like the sun is up it has a different hour than when the moon is up. The earth soins 15 degrees per hour. The sun rises in L.A. at the same minute than N.Y. when it is getting dark.

Five Stages Of Sleep ... Sleep Cycles Explained - 2 views
-
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.
-
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.

Dolphin Families - 0 views
-
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.
