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 […]
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 […]
What is called self inductance?
What is called self inductance? Self-inductance: Self inductance is defined as the phenomenon in which a change in electric current in a circuit produces an induced electro-motive-force in the same circuit. What is coefficient of self inductance? Definition: coefficient of self inductance. The ratio of the back EMF to the rate of change of current […]
Which macromolecule is most important to life?
Which macromolecule is most important to life? proteins Which macromolecule has the most energy? There are four classes of biological molecules: fats, carbohydrates, proteins, and nucleic acids. Of these, fats produce the most energy per gram at a whopping nine calories per gram. Carbohydrates and proteins produce less than half of this, at only four […]
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 […]
What is the #1 cancer killer?
What is the #1 cancer killer? According to the American Cancer Society, lung cancer — and lung cancer caused by asbestos — is the number one killer, with 142,670 estimated deaths in 2019 alone, making it three times deadlier than breast cancer. What’s the most curable cancer? What are the most curable cancers? Breast cancer. […]
What is the change in velocity per time?
What can atoms do to achieve stability?
What can atoms do to achieve stability? To achieve greater stability, atoms will tend to completely fill their outer shells and will bond with other elements to accomplish this goal by sharing electrons, accepting electrons from another atom, or donating electrons to another atom. Why do atoms need 8 electrons to be stable? A complete […]
Can you drive car if brakes are grinding?
Can you drive car if brakes are grinding? Do your brakes make a grinding noise that you can feel in the pedal? If so, stop driving immediately and have your vehicle towed to a brake repair shop. Further driving could damage the brake discs or drums. Can Low brake fluid cause grinding? Can Low brake […]
