Functions of the Eyes Cornea : The cornea is the outer covering of the eye. This dome-shaped layer protects your eye from elements that could cause damage to the inner parts of the eye. There are several layers of the cornea‚ creating a tough layer that provides additional protection. These layers regenerate very quickly‚ helping the eye to eliminate damage more easily. The cornea also allows the eye to properly focus on light more effectively. Those who are having trouble focusing their eyes properly can

Introduction: Our environment plays a major role in contributing to the causes of the cancer disease. Taking a closer look at skin cancer for instance‚ we see how much of the effects of the sun’s dangerous UV rays can harm our bodies. What constitutes an environmental cause of cancer? When we talk about environmental causes of cancer‚ we are referring to the effects of environmental exposures or conditions that have direct or indirect effect on the origin or formation of the cancer disease in

concentration gradient. The molecular size vs the MWCO size of the membrane can either increase‚ decrease‚ or prevent diffusion. The greater the concentration gradient the greater the diffusion rate due to molecules moving from areas of higher concentration to areas of lower concentration. • Why do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction? My prediction was correct. The molecular weight of urea is 60.07

The following will discuss the male sexual anatomy‚ physiology‚ and overall sexual health. In examining the male sexual body‚ the anatomy encompasses both the external and the internal sex organs. The external sex organs consist of the penis and the scrotum. The internal sex organs consist of the testes‚ genital ducts‚ and the fluid producing

What is exercise physiology? Exercise physiology is the science that describes‚ explains and uses the body’s response to exercise and adaption to exercise to maximise human physical potential. Exercise physiology is very important in touch because the amount of physical activity our body can tolerate‚ the better we will play for the longest amount of time. ATP/CP system is used by the body to produce ATP quickly in the absence of oxygen. High intensity activities lasting for less than 10 seconds
