Aquaporins are "the plumbing system for cells‚" said Agre. Every cell is primarily water. "But the water doesn’t just sit in the cell‚ it moves through it in a very organized way. The process occurs rapidly in tissues that have these aquaporins or water channels." For many years‚ scientists assumed that water leaked through the cell membrane‚ and some water does. "But the very rapid movement of water through some cells was not explained by this theory‚" said Agre. Aquaporins selectively conduct

Before World War I‚ films were being made mostly European countries and in Japan. When the war interrupted European filmmaking‚ however‚ the American film industry began to dominate the world market. In the years between 1917 and 1927 the silent film reached the peak of its development. United States had the largest film industry and American films dominated the international market. Germany and Japan still had some movie industries but mostly left to domestic. Many nations found film production

Shanise Hawes 04/04/2012 Simple Harmonic Motion Lab Introduction: In this two part lab we sought out to demonstrate simple harmonic motion by observing the behavior of a spring. For the first part we needed to observe the motion or oscillation of a spring in order to find k‚ the spring constant; which is commonly described as how stiff the spring is. Using the equation Fs=-kx or‚ Fs=mg=kx; where Fs is the force of the spring‚ mg represents mass times gravity‚ and kx is the spring constant

all know that penicillin is one of the top known class of antibiotics prescribed today. Although this drug has been getting numerous applauds since the mid 1900s on its effectiveness; it did not start at that way. The biggest challenge to this discovery was it mass production‚ which later came down the road. This drug was discovered in a very unusual way by Alexander Fleming in 1920. Fleming had returned from a summer vacation and began sorting petri dishes‚ which contained colonies. Which are

Rosalind Franklin Crick and Watson‚ together with Maurice Wilkins‚ won the 1962 Nobel Prize in physiology or medicine for their 1953 determination of the structure of deoxyribonucleic acid (DNA) this was one of the most significant scientific discoveries of the 20th century. James Watson and Francis Crick discovered the molecular structure of DNA model of the structure resembled a twisted rope ladder. They proposed that the DNA molecule consisted of two spirally wound‚ helical chains. Rosalind

Through the use of numerical measure‚ the Motion Picture Industry can be analyzed more specifically. Descriptive statistics can assist analyst to measure data in terms of location‚ variability‚ association between two variables‚ as well as using data for exploratory analysis and the shape‚ relative location‚ and the identification of outliers. The data presented offers a look at four data sets including opening gross income‚ total gross income‚ number of theaters‚ and weeks in the top 60 movies

Lab {4} Free Fall Motion Abstract Within this laboratory students used a Macintosh computer‚ scientificwork interface‚ and photogate to measure the acceleration of gravity‚ g‚ in a free-fall experiment. Using a “picket fence” dropped through a photo gate with disregard for air resistance; students calculated the results from the charted data and compared it with the accepted value of 9.8 m/s2 discussing any variations and their

Now click and drag the red ball around the screen. Make 3 observations about the blue and green arrows (also called vectors) as you drag the ball around. The vectors appear to have both direct and inverse relationships with each other. When I move the ball one direction‚ both of the vectors move the

ROTATIONAL MOTION CENTRE OF MASS AND ROTATIONAL MOTION INTRODUCTION- For describing the motion of rigid bodies‚ we shall introduce the key concept of ‘centre of mass’. This concept enables us to understand how we can apply justifiably the Newton’s laws of motion‚ in essentially the same form to objects of large size including even the astronomical objects like the planets and the stars. KINDS OF MOTION OF A RIGID BODY- A rigid body may have three kinds of motion- (1) Pure Translation Motion- in such
