the fetus and there are no controlled studies in women. Drugs should be given only if the potential benefits justify the potential risk to the fetus. Category D: There is positive evidence of human fetal risk (unsafe)‚ however in some cases such as a life-threatening illness the potential risk may be justified if there are no other alternatives. Category X: Highly unsafe: risk of use outweighs any potential benefit. Drugs in this category are contraindicated in

maximum gravitational potential energy. As the pendulum falls the potential energy is transferred to kinetic energy. The speed increases as the pendulum falls and reaches a maximum at the bottom of the swing. Here the speed and kinetic energy are a maximum‚ and the potential energy is a minimum. As the pendulum rises the kinetic energy is transferred back to potential energy. The speed of the pendulum decreases and falls to zero as it reaches the top of its swing‚ with the potential energy a maximum again

Basic Biochemistry CP2085 Effect of Temperature‚ Study and Measure of Enzymes Activity Abstract This experiment investigates the effect that temperature has on the rate of activity of enzyme β-galactosidase and also the rate of β-galactosidase activity in different concentration of substrate over time. Ο-nitrophenylgalactoside (ONPG) is used as a substrate for β-galactosidase. A spectrophotometer is used to detect the change in colour of the substrate. Results show that increase in temperature

Half of the fans yell insults; the other half of the fans shout their approval. The event reminds you of the topic of today’s lecture in psychology class. What was the likely topic of the lecture? Student Answer: bias experiments psychoanalysis extraneous variables Instructor Explanation: Chapter 1

pump is a protein that hydrolyses ATP in order to transport a particular solute through a membrane in order to generate an electrochemical gradient to confer certain membrane potential characteristics on it. This gradient is of interest as an indicator of the state of the cell through parameters such as the Nernst potential. In terms of membrane transport the gradient is of interest as it contributes to increased system entropy in the co-transport of substances against their gradient. One of the

aircraft of mass 1200 kg is cruising at 250 km/h at an altitude of 2000 m. What is the gravitational potential energy (relative to the ground)‚ and what is the kinetic energy of the aircraft? m=1200 kg v=69.44 m/s Δh=2000 m Eg=mgΔh Eg=(1200)(9.8)(2000) Eg=23520000 J Ek=½mv2 Ek=½(1200)(69.44)2 Ek=2893148.16 J If the pilot puts the aircraft into a dive‚ what will be the gravitational potential energy‚ what will be the kinetic energy‚ and what will be the speed when the aircraft reaches an altitude
