A Three Second Memory? There is a common belief that fish only have a three second memory and that they cannot be trained to compete tricks, and this may be caused by the short lifespan of some species of fish, making testing for long term memory difficult (Reebs, 2008, p.1). Moreover, many assume that goldfish do not have a memory since goldfish always seem like they are hungry, since they are always seen foraging for food. However, as a long time goldfish owner, I have witnessed my goldfish…

Bowen (1913-1990), developed in the early 50 's theory of natural systems, based on observation of the processes that take place in humans from a natural point of view.

Giving Up a Sense Out of the five senses, sight, hearing, taste, smell, and touch, I would choose to give up smell. Giving up smell also includes giving up taste. Although I love the taste of food, or the smell of the different seasons, I feel that smell and taste are the senses that I least need and will make less of an impact on my daily life, rather than if I took one of the other senses away. Being able to not go out with friends and enjoy food, or discuss how something tastes would be…

There is no clear predetermined linkage between a specific subtype and a unique mode of transmission. Therefore, different subtypes could have been influenced by a combination of different genetic, demographic, economic and social factors that separate the different risk groups for HIV-1. HIV is not an airborne virus and cannot be transmitted through casual contact, kissing, urine or even insect vectors [17]. The transmission is only possible if bodily fluids come in contact with a mucous…

I find it very funny that every age is mocking the elders and title them as being stereo type, I used to laugh -in my secret of course- when my mother put her thick glasses and try hardly to dive in her IPhone options, that she got recently, and after a while, she gets tired and shouts for someone of us to help her to access to her Facebook account, it seems to no matter how many times we try to teach her something, she forgets the other. Every are has its own trend or known for something, and…

The human immune response is a complex, layered system that uses multiple defense mechanisms which function in harmony to protect the body from infection and illness. There are two main types of immune response, the innate and acquired, and while these responses are related and sometimes overlap, they use separate processes to defend against invaders. Working as a whole, innate and acquired immune responses protect the body from infectious organisms. Infectious organisms that can cause disease…

What is “reinforcement”? There are two types of reinforcement: positive reinforcement and negative reinforcement. With positive reinforcement, you add something desirable in order to increase a certain response. For example, when a child uses manners, the parent rewards the child with praise or a sign of approval. The child will then do more in order to get that response from their parent. With negative reinforcement, you add an uncomfortable situation or take something away to make the…
