Diffusion is when molecules move into available space. It’s the spread of something more widely. Substances diffuse in high concentrated area to a low concentrated area. Water is one molecule that can diffuse freely in a cell. Other molecules need assistance through the cell membrane through a process called facilitated diffusion. Osmosis moves from an area of low concentration to high concentration. In osmosis water moves in the opposite way. Water flow is determined by the concentration‚ not

Biomedical engineering is a very broad kind of engineering‚ comprised of many elements. There are several different topics to research more in depth‚ like tissue engineering‚ genetic engineering‚ building prosthesis or even making artificial organs. Artificial organ building is an advanced technology to help improve the quality of life‚ but has many ethical arguments many people do not agree with. Dr. Alan Flake is the leader of a project at the Children’s Hospital of Philadelphia‚ where they are

cells can be used to treat a condition such as paralysis. Explain why. stem cells can differntiate to become any type of body cell so they could be used to replace the damaged nerve cells‚ (2) (b) During pregnancy‚ an umbilical cord and a placenta join the embryo to the mother. At birth the umbilical cord is cut. Stem cells can be obtained from the umbilical cord. Many people think that the stem cells for treating human conditions should be obtained from umbilical cords rather than human embryos

The aim of this paper is to critique recent research and literature around the use of paracetamol in treating PDA. Background In the foetal circulation‚ the primary role of the DA is to divert the ventricular output away from the lungs towards the placenta in utero by its connection between the pulmonary artery and the descending aorta. Its patency is regulated by low oxygen tension present in the foetal lung and prostaglandin‚ which is known for its vasodilating effect in the placental circulation
