Why is fluidity of the membrane important? Fluidity is important for many reasons: 1. it allows membrane proteins rapidly in the plane of bilayer. 2. It permits membrane lipids and proteins to diffuse from sites where they are inserted into bilayer after their synthesis. How do membranes stay fluid? The cell membranes remain fluid due […]
Why is attribution important to psychology?
Why is attribution important to psychology? Attribution psychology helps to explain our behavior and how we perceive the way others act. It helps us sort out our personal biases-good and bad. What is attribution and why is it important? Marketing attribution is important because it makes the marketing realm a bit less complex and easier […]
Can you get paid with a private pilot license?
Can you get paid with a private pilot license? The private pilot license affords you a middle ground. The FAA permits private pilots to share flight expenses with passengers as well as get paid for a limited number of jobs like towing gliders or being an aircraft salesman. But if you think about it, your […]
How do you calculate the change in liquid temperature?
How do you calculate the change in liquid temperature? This is easy. You subtract the final temperature from the starting temperature to find the difference. So if something starts at 50 degrees Celsius and finishes at 75 degrees C, then the change in temperature is 75 degrees C – 50 degrees C = 25 degrees […]
Does sonar affect fish?
Does sonar affect fish? It is a finding that Popper says “should not be extrapolated to other fish species or the effects of other sound sources.” There is considerable concern that human-produced (anthropogenic) sounds added to the environment could have damaging effects on marine life. What is the basic principle of sonar? Sonar are electronic […]
What is the difference between the two types of igneous rocks?
What is the difference between the two types of igneous rocks? The two main categories of igneous rocks are extrusive and intrusive. Extrusive rocks are formed on the surface of the Earth from lava, which is magma that has emerged from underground. Intrusive rocks are formed from magma that cools and solidifies within the crust […]
Which best describes thermionic emission?
Which best describes thermionic emission? Thermionic emission is the emission of electrons from a heated metal (cathode). As the temperature increases, the surface electrons gain energy. The energy acquired by the surface electrons allows them to move a short distance off the surface thus resulting in emission. Where is the focusing cup located? A focusing […]
What is the process of a muscle contraction?
What is the process of a muscle contraction? Muscle contraction occurs when the thin actin and thick myosin filaments slide past each other. It is generally assumed that this process is driven by cross-bridges which extend from the myosin filaments and cyclically interact with the actin filaments as ATP is hydrolysed. What determines the strength […]
Do lions attack humans?
Do lions attack humans? Cases in Lindi have been documented where lions seize humans from the centre of substantial villages. It is estimated that over 250 people are killed by lions every year. Man-eating lions studies indicate that African lions eat humans as a supplement to other food, not as a last resort. Do lions […]
Is a potential energy?
Is a potential energy? Potential energy, stored energy that depends upon the relative position of various parts of a system. A spring has more potential energy when it is compressed or stretched. A steel ball has more potential energy raised above the ground than it has after falling to Earth. What are the units of […]
