A singular point, which is of the form: (x−h)2a+(y−k)2b=0. … A line, which has coefficients A=B=C=0 in the general equation of a conic. … A degenerate hyperbola, which is of the form: (x−h)2a−(y−k)2b=0. What is the meaning of degenerate conics? In geometry, a degenerate conic is a conic (a second-degreeRead More →
A normal female karyotype is written 46, XX, and a normal male karyotype is written 46, XY. What is the gender of YY? Males with XYY syndrome have 47 chromosomes because of the extra Y chromosome. This condition is also sometimes called Jacob’s syndrome, XYY karyotype, or YY syndrome. AccordingRead More →

A precipitin reaction typically involves adding soluble antigens to a test tube containing a solution of antibodies. Each antibody has two arms, each of which can bind to an epitope. When an antibody binds to two antigens, the two antigens become bound together by the antibody. What are the limitationsRead More →
Some characteristics that have distinguished hominins from other primates, living and extinct, are their erect posture, bipedal locomotion, larger brains, and behavioral characteristics such as specialized tool use and, in some cases, communication through language. What evidence have scholars used to reconstruct early hominids history? Fossils: The most obvious wayRead More →
Viscosity is the measure of a substance’s resistance to motion under an applied force. The formula for measuring viscosity is fairly simple: viscosity = shear stress / shear rate. The result is typically expressed in centipoise (cP), which is the equivalent of 1 mPa s (millipascal second). What are theRead More →
Multiplying a decimal by 10 moves the decimal point one place to the right. Dividing a decimal by 10 moves the decimal point one place to the left. Multiplying or dividing by a power of 10 will move the decimal point equal to the number of 0s. Which way doRead More →
Near the top of the compression stroke, the spark plug fires. The piston reaches TDC. As the piston reaches TDC, the air/fuel mixture burns, increasing the pressure inside the cylinder. This forces the piston back down the cylinder. Is the piston at top dead center or bottom dead center? TDCRead More →
Why are Cepheid variables important in astronomy? Cepheids variables are pulsating stars whose pulsation periods are directly related to their true luminosities. Therefor they can be used as distance indicators. What is Hubble’s law? What makes a Cepheid variable? A Cepheid variable (/ˈsɛfiːɪd, ˈsiːfiːɪd/) is a type of star thatRead More →
