What is tolerance in a resistor? The tolerance of a resistor is the maximum difference between its actual value and the required value and is generally expressed as a plus or minus percentage value. For example, a 1kΩ ±20% tolerance resistor may have a maximum and minimum resistive value of: Maximum Resistance Value. What are […]

How can protein synthesis be increased? Ten grams of essential amino acids or twenty-five grams of a complete protein are sufficient to maximally stimulate protein synthesis. Type, timing and amount of protein are all factors in maximizing muscle mass. How do you explain protein synthesis to a child? Protein synthesis is a term that means […]

What is meant by 1 molar solution? A 1 molar (M) solution will contain 1.0 GMW of a substance dissolved in water to make 1 liter of final solution. Hence, a 1M solution of NaCl contains 58.44 g. How do you make 200ml of a 0.1 M solution? How do we make the 0.1 M […]

How is the movement of matter and energy different in an ecosystem? Nutrients can also cycle out of an ecosystem. Energy enters an ecosystem at any level and leaves at any level, while the flow of matter does not. The flow of matter cycles freely between trophic levels and between the ecosystem and the physical […]

Can a peregrine falcon kill a human? A peregrine has between 4 to 8 times as much mass as a baseball, and can move at twice the speed of a fastball. That’s between 16 and 32 times the kinetic energy of a baseball. It is difficult to estimate the time of the collision accurately, but […]

What is always true when there is sea breeze? Sea breezes occur during hot, summer days because of the unequal heating rates of land and water. During the day, the land surface heats up faster than the water surface. Therefore, the air above the land is warmer than the air above the ocean. Recall that […]

What are the 4 elements of science fiction? Science fiction contains the usual elements of the novel: a specific setting, character development, plot (central conflict, complications, climactic events, resolution), themes, and structure. How can you tell if a story is science fiction? Science fiction is a genre of fiction in which the stories often tell […]

Why does path of light beam become visible while passing through a smoked room? Smoke is made up of tiny particles. The particles reflect light rays to all directions, including where we stand. As a result, we can see the path of the beam on the side. What is the example of Tyndall effect? When […]

What produces new cells during growth and repair? The Purpose of the Reproduction Both sexual and asexual organisms go through the process of mitosis. It happens in the cells of the body known as the somatic cells and produces cells related to growth and repair. Mitosis is essential for asexual reproduction, regeneration, and growth. Do […]

What are the 3 causes of scarcity? In economics, scarcity refers to resources that a limited in quantity. There are three causes of scarcity – demand-induced, supply-induced, and structural. There are also two types of scarcity – relative and absolute. How does scarcity affect your life examples? Scarcity of resources can affect us because we […]
