1. The Study of the human mind and human behaviour - to see how human emotions and thinking correlate and cause everyday actions and feelings such as "Why does someone who grew up here tend to think like this" or "Why does someone who was bad at acting feel at home on a stage in any other capacity". although its still hard to completely define though. For example, psychology could be defined as the science behind human mental thought processes but then behaviorist psychology approach has shown that animals with much simpler cognitions can learn to think in certain ways.

2. There are three main types of descriptive methods: observational methods, case-study methods and survey methods.

The second method is the Case study research involves an in-depth study of an individual or group of individuals. The last method is the survey method in which participants answer questions administered through interviews or questionnaires.

3. The Cerebrum
In the cerebrum, there are fifty hundred to one hundred thousand neurons, the telegram of information is sent from place to place like a telegram. The cerebrum is divided in to two hemispheres, the right and left hemispheres. The dividing point is a deep grove called the longitudal cerebral fissure. The different sides of the cerebrum do different things for the opposite sides of the body. The right side of the cerebrum controls things such as imagination and 3-D forms. The other side of the brain, the left side, controls numbering skills, posture, and reasoning. The hemispheres also consist of many other parts such as the lobes. The Cerebellum
The cerebellum is the part of the brain where the high level functions take place. The cerebellum conrtols posture, balance, and coordination. It is divided into two differene lobes which are connected by white fibers. Also in the cerebellum, there is folia, bundled nerve cells. The brain stem is located directly below the cerebellum. The Brain Stem
The brain stem connects the spinal cord with the spinal cord. It is also the part of the brain where the vital functions occur. The lowest part of the brain is located in the brain stem, the meddula oblangata. Directly above the meddula oblangata are the pons. The pons is the band of nerves that connect the cerebrum, the cerebellum, and the meddula oblangata. The meddula oblangata is in the middle of the brain and controls breathing. Above the pons is the mid brain.

4. Light enters your eye through a clear portion of the sclera, called the cornea. The cornea is curved, so it slightly bends the light as it goes through. Light then passes through the aqueous humor and then through the pupil. The pupil is simply a hole in the iris. The iris is a muscle that controls how large the pupil is. It is the colored part of the eye. In low light, the iris contracts and the pupil gets bigger; in bright light, the iris expands and the pupil gets smaller. Directly behind the iris is the lens. This is…
