Activity One: 1. The two major variables that affect the rate of diffusion: a. The composition of the lipid bilayer (eg. more cholesterol‚ less permeability to polar substances) b. The structure of the molecule undergoing diffusion (eg. steric conformation‚ size‚ polarity‚ amount and strength of hydrogen bonding) 2. Urea was not able to diffuse through the 20 MWCO because the pores of the membrane were too small for the urea to pass through. The molecular weight of urea is 60.06 g/mol‚ over

with a piece of string‚ to travel a distance h is equal to the calculated time of the same height. An example of flywheel applications is the replacement of substations in railway systems with flywheel systems. The number of passenger on trains are increasing‚ increase the weight load on the train‚ the spacing between trains decreases and voltage drops are becoming more common on rail systems. Substations can be upgraded to add power conditioning equipment‚ space constraints and difficulty of increasing

Metabolic rate refers to the “amount of oxygen consumed by the body cells” (Farlex‚ n.d.). it can be affected by numerous factors‚ some of which being the mass of the animal‚ its physical activity and temperature. Invertebrates are able to live in highly variable conditions due to their metabolism having evolved over time. Homeotherms are animals that are able to maintain a specific body temperature without relying on the temperature from its surroundings. Poikilotherms on the other hand do the exact

Our heart pump approximately 20% of blood in our brain. The brain needs constant blood flow in order to keep up with the heavy metabolic demands of the neurons. The brain is the main control center for all individual activities. It controls our muscular activities or movements and similarly it stores our happy and sad memories. It correspondingly provide emotions like happiness‚ sadness‚ angriness and other emotions that we feel. The brain is main part of our nervous system. Nervous system is a

There are 206 bones in the human body of the adult skeleton. The adult skeleton is broken up in two divisions: the axial skeleton‚ and the appendicular skeleton. The axil skeleton is made up of 80 bones‚ and the appendicular skeleton is made up of 126 bones. As for the different systems of the body‚ we dissected a fetal
