What triggers the sodium-potassium pump? The sodium–potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell. […]
What organisms are responsible for nitrogen fixation?
What organisms are responsible for nitrogen fixation? Two kinds of nitrogen-fixing microorganisms are recognized: free-living (nonsymbiotic) bacteria, including the cyanobacteria (or blue-green algae) Anabaena and Nostoc and genera such as Azotobacter, Beijerinckia, and Clostridium; and mutualistic (symbiotic) bacteria such as Rhizobium, associated with leguminous plants. How is nitrogen produced? Commercial production of nitrogen is largely […]
What are the five styles of acculturation?
What are the five styles of acculturation? Five Different Strategies and Outcomes of Acculturation Assimilation. This strategy is used when little to no importance is placed on maintaining the original culture, and great importance is put on fitting in and developing relationships with the new culture. Separation. Integration. Marginalization. Transmutation. What are the 4 types […]
Why is it important to specify both magnitude and direction?
Why is it important to specify both magnitude and direction? To fully describe the object’s velocity, both magnitude (25 m/s) and direction (e.g., south) must be stated. In order for such descriptions of vector quantities to be useful, it is important that everyone agree upon how the direction of an object is described. What is […]
What animal has the best regeneration?
What animal has the best regeneration? Axolotl. A relative of the salamander but even more skilled at regenerating is the axolotl. This animal can regenerate not just its tail but also limbs, skin and almost any other body part. Researchers found that each time a limb was removed, it regrew almost perfectly. Which animal can […]
Why do cells form tissues?
Why do cells form tissues? Cells are grouped together to carry out specific functions. A group of cells that work together form a tissue. Your body has four main types of tissues, as do the bodies of other animals. These tissues make up all structures and contents of your body. How do cells specialize? Cell […]
What is difference between potential and voltage?
What is difference between potential and voltage? Electrical potential is the energy per unit charge gained or lost when a charge is moved from some reference point at which the potential is defined to be zero. Voltage is the difference in potential between two arbitrary points at which the potential is not necessarily zero. What […]
What is the basic principle for increasing friction?
What is the basic principle for increasing friction? The basic principle for increasing friction is by increasing the roughness of the surfaces in contact. What is principle of friction? 1) The force of friction always acts in a direction, opposite to that in which the body tends to move, if the force of friction would […]
Are transverse waves faster than longitudinal?
Are transverse waves faster than longitudinal? No, longitudinal waves travel faster than transverse waves. The longitudinal wave transmission is faster than transverse wave transmission. This speed difference between the longitudinal and transverse wave can be noticed during an earthquake. What is the difference between transverse and longitudinal waves BBC Bitesize? The direction of these oscillations […]
What do you mean by deductive method?
What do you mean by deductive method? Deductive reasoning, also deductive logic, is the process of reasoning from one or more statements (premises) to reach a logical conclusion. If all premises are true, the terms are clear, and the rules of deductive logic are followed, then the conclusion reached is necessarily true. What is induction […]
