Perform at least one exercise for each major muscle group on a stability ball. On another day‚ perform the same exercises in a stationary position (i.e.‚ not on a stability ball.) Report the following. List the exercises you performed. Were you able to use the same weight on the stability ball? If not‚ why do you think you could not use as much resistance? What populations would benefit from stability ball training? Are there certain individuals who should not use a stability ball? How will this

Continental Temperature Ranges Introduction: There are large variations in average monthly temperatures among cities located at the same latitude. This suggests that factors besides the angle and duration of isolation affect the rate heating and cooling of any given location. Objective: You will graph the average monthly temperatures of costal and inland continental regions and interpret the range in temperatures. Vocabulary: Temperature range- Average daily temperature Average monthly

Transport Mechanisms and Permeability: Simulating Dialysis (Simple Diffusion) 1. Describe two variables that affect the rate of diffusion. Molecular weight affects the rate of diffusion because the bigger the size of the molecule the longer it will take to diffuse. Membrane size is another variable that affects the rate of diffusion because if the membrane’s pores are small it will take molecules longer to diffuse though it than if the pores were larger. Also‚ membrane thickness is a variable

Describe the structure and function of each of the eukaryotic organelles. ”A eukaryotic cell is sectioned by internal membranes into different functioning categories called organelles. For example‚ the nucleus houses DNA‚ the genetic component that controls the cells activities. (Boundless. “Introduction” Boundless Biology). The Cytoplasm is the material between the cell membrane and the nucleus. It has a lot of responsibilities within the cell. It contains enzymes for breaking down waste and also

Introduction: Temperature - Is a measure of the motion of particles‚ increasing the temperature will cause the particles to move faster because the reactant particles have more thermal energy from the heat. When particles move faster‚ more frequent collisions will occur and the collisions are more violent. This should increase the reaction rate. This will result in the particles colliding more frequently and increasing the speed of the reaction. Also when they have more energy there will be more

Premature Rupture of Membranes Article Review As the article states‚ premature rupture of membranes occurs when the amniotic membranes surrounding the growing fetus rupture causing a loss of fluid before 37 weeks of gestation and before the onset of natural labor. PPROM‚ preterm premature rupture of membranes is seen often in women who smoke and use recreational drugs. If PPROM occurs before 26 weeks of gestation it is considered extreme and more often than not leads to more serious complications

Chapter 15 & 16: Temperature‚ Heat & Heat Transfer Temperature is a measure of the average (not total) translational kinetic energy. ●ex: there is 2x as much total molecular kinetic energy in a 2L of boiling water than one‚ but the temp of the two volumes are the same (average of translational kinetic energy per molecule is the same in each → Internal Energy- the total of all molecular energies: kinetic+potential (SAME TEMP) ● Ex: apply a flame to 1L h2o for a certain time and its temp rises

through the epithelial cell membrane to enter into the epithelial cell’s cytoplasm – its charged cuz of side chains To get through the membrane the amino acid must cross the Simple columnar epithelial cells lining the apical surface of the small intestinal tract. These cells are impermeable to any harmful bacteria that may be ingested by the body‚ but permeable to necessary ions. Absorption of amino acids occurs through a process known as facilitated diffusion through membrane transporters (carrier protein)

1a. Aquaporins are membrane proteins that have fourteen various structures however the most common form is that of a homotetramer. The homotetramer is often found in the membrane and composed of four aquaporin membranes. The structural arrangement creates a fifth channel in the middle that allows for gas transportation. 1b. The direction of H2O molecular flow through a channel is determined by an osmotic gradient. 1c. One of the mechanisms that prevents proton channeling is due to the (ar/R) and
