What are the 5 types of gene mutations? What kinds of gene variants are possible? Missense. A missense variant is a type of substitution in which the nucleotide change results in the replacement of one protein building block (amino acid) with another in the protein made from the gene. Nonsense. Insertion. Deletion. Duplication. Frameshift. Repeat […]

What are 2 types of cellular respiration? There are two main types of cellular respiration—aerobic respiration and anaerobic respiration. Aerobic respiration is a specific type of cellular respiration, in which oxygen (O2) is required to create ATP. What is the fundamental difference between photosynthesis and cellular respiration? What is the relationship between photosynthesis and cellular […]

Is force dimensionless quantity? The ratio of the internal forces to the external forces will depend upon its speed, and the viscosity of the fluid, and the size of the body. But the ratio of the internal to the viscous forces is dimensionless, so it must depend on some combination of the viscosity, speed V […]

What are two sides of a ray called? In plane geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. How do you name a 3 point line? Collinear is when you have three or more points on a […]

What happens at the beginning of every roller coaster ride? What happens at the beginning of every roller coaster ride? The car is pulled up a long hill. [The roller coaster cannot go higher than the first hill because the total energy of the roller coaster cannot increase unless energy is added.] What happens to […]

What are the properties of ellipse? Key Takeaways An ellipse is formed by a plane intersecting a cone at an angle to its base. All ellipses have two focal points, or foci. All ellipses have a center and a major and minor axis. All ellipses have eccentricity values greater than or equal to zero, and […]

What are the 5 Rules of contour lines? Rule 1 – every point of a contour line has the same elevation. Rule 2 – contour lines separate uphill from downhill. Rule 3 – contour lines do not touch or cross each other except at a cliff. Rule 4 – every 5th contour line is darker […]

Who invented the electricity we use today? Benjamin Franklin What is the application of electricity in our daily life? Electricity is an essential part of modern life and important to the U.S. economy. People use electricity for lighting, heating, cooling, and refrigeration and for operating appliances, computers, electronics, machinery, and public transportation systems. What is […]

What happens to the resistivity of wire if it is stretched? The resistance of a wire is inversely proportional to its area and directly proportional to its length. When the length is tripled then resistance will also become three times. If The wire is stretched 3 times the original length, the cross-section of the wire […]

Which item will sound travel faster? Solids: Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air. Why […]
