how hydrogen bonding occurs between water molecules‚ and relate this and other properties of water‚ to the roles of water in living organisms. Water is a very small molecule‚ consisting of two hydrogen atoms covalently bonded to an oxygen atom. However the electrons shared are not done so equally‚ oxygen is more electronegative and has a firmer hold on the electrons and pulls them slightly towards its nucleus. Due to this‚ the charge across the molecule of water is not equally distributed‚ and the

concept of working memory and how it actually works and is able to function alongside all other kinds of memory. The beginning of this article starts off by trying to determine the relationship between working memory and cognitive abilities.

Clean water is extremely essential for a healthy living. It is life’s most important basic necessity while dirty water is one of the deadliest killers. UN has estimated that 10 people die every minute from contaminated water. The World Health Organization estimates that 80% of all sickness and disease in developing countries is due to unsafe water. As water pollution is one of the most widespread problems and it has deadly effects‚ I chose this topic. Water pollution is the contamination of water bodies

The Heart and Circulation of Blood In this research paper‚ I will be analyzing the process of blood circulation within the human body. I will be focusing on the pulmonary circuit and the systemic circuit‚ as well as the relationship with the hepatic portal system. The combination of these systems allows the body to function properly and maintain unconscious homeostasis. I will also be talking about the effects that fitness and diet have on these processes. The pulmonary circuit passes already-used
