Guts‚ and Brains Seminar Summary During the seminar “Bugs‚ guts and brains: How gut microbiota shapes your mind and body” on November 7‚ Physiologist from UC Davis‚ Dr. Helen Raybould discussed how gut microbes in humans and animals affects neurophysiology based primarily on the foods we eat and the genes expressed in the gut. There is an intersection between micro and host physiology that affects the overall health and behavior of the host. To understand this‚ the neural pathways by which macronutrients

Impulse and Momentum Lab Part I: As the first lab of the Physics 2 curriculum‚ our class completed a lab experiment that introduced us students to a new concept that would be a foundation to the future topics that we learn in this class. In this lab activity‚ we used a lab cart on a flat track to compare the collision of the cart with a force sensor with and without the plunger during different trials. The materials that we would need for this activity are a lab cart on a flat track‚ a timer

Your answer : d. An increase in muscle length will decrease the total force. Stop & Think Questions: Note the dip in total force at a muscle length of 90 mm. Why does this occur? You correctly answered: d. At this muscle length‚ active force has decreased in

Describe two variables that affect the rate of diffusion. Your answer: The two variable that affect the rate of diffusion are as follows: -the composition of the lipid layer which can vary from tissue to tissue -the size of the molecule(the larger the size the slower the rate of diffusion) 2. 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? Your answer: The urea was not able to diffuse through 20 MWCO membrane

Abstract Pyromania is an impulse control disorder categorized by the DSM-5 as “deliberate and purposeful fire-setting on more than one occasion” combined with “tension or affective arousal”‚ “pleasure‚ gratification or relief when setting fires or when witnessing or participating in their aftermath” (American Psychiatric Association‚ 2013). Also‚ those diagnosed with pyromania aren’t setting fires for monetary gain‚ to conceal crimes‚ as an expression of emotion or ideology‚ or because of impaired
