Simple Diffusion 1. The following refer to Activity 1: Simulating Dialysis (Simple Diffusion). Which solute(s) were able to pass through the 20 MWCO membrane? None According to your results‚ which solute had the highest molecular weight? Albumin Which solute displayed the highest rate of diffusion through the 200 MWCO membrane? NACI_ Using the data from Chart 1‚ explain the relationship between the rate of diffusion and the size of the solute. The smaller the solute particle‚ the greater

Week 7 Checkpoint: Physiology Assignment I chose to look up a diagram on a sea dwelling organism known as a Jellyfish. Jellyfish have many different forms and are often characterized in different groups. One jellyfish that stood out to me was the Aurelia or also known as the Moon Jellyfish‚ which is like the basic jellyfish that I’ve always seen in pictures and books growing up. Jellyfish are said to be very effective predators‚ as one point in the time they were considered to be at

Unit 1- Principles of Anatomy and Physiology Functions of the skeletal system There are five main functions of the skeletal system. To protect‚ to support‚ movement‚ cell production and storage. The skeletal system protects delicate and important organs from harm. An example of this is the ribcage. This protects your heart and lungs from anything that tries to harm it. Another example is the brain. The brain is protected by the skull. The skeletal system also provides support for the body as it

In general appearance‚ Gray Wolves resemble a large dog‚ but wolves have longer legs‚ larger feet‚ a narrower chest‚ and a straight tail. The gray wolf’s head is large and heavy‚ with a wide forehead‚ strong jaws‚ and a long muzzle. The ears are small and triangular. They carry their head at the same level as the back‚ raising it only when they’re alert. Their fur is thick‚ with an outer layer composed of coarse hair‚ and a soft undercoat. Their coat color is usually grey flecked with black but can

Review Sheet 1 Results 1. Describe two variables that affect the rate of diffusion. Your answer: Two variables that affect the rate of diffusion are the MWCO membrane and the solute concentration. Increasing the membrane size and solute concentration will also increase the average diffusion rate. Decreasing the membrane size and solute concentration will reduce diffusion rates and can even prevent all diffusion. 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane
