# Heredity

Heredity, the sum of all biological processes by which particular characteristics are transmitted from parents to their offspring. The concept of heredity encompassestwo seemingly paradoxical observations about organisms: the constancy of a speciesfrom generation to generation and the variation among individuals within a species. Constancy and variation are actually two sides of the same coin,…

# Parallel lines

What is Parallel lines? Parallel lines are the subject of Euclid‘s parallel postulate.[1] Parallelism is primarily a property of affine geometries and Euclidean geometry is a special instance of this type of geometry. In some other geometries, such as hyperbolic geometry, lines can have analogous properties that are referred to as parallelism.

# Parallel lines

Parallel lines In geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. By extension, a line and a plane, or two planes, in three-dimensional Euclidean space that do not share a point are said to be parallel.   :…

parallel lines what is parallel lines       Parsley lines are two lines that Arab always the same distance  apart are never touch. on order for two lines to  be parallel,they must be drawn in the same plane,a perfectly flat surface like a wall or sheet of paper. what are  interior angles  …

# what is heredity?

Heredity is only half the story Robert Plomin argues that ‘only DNA matters’, making it possible to ‘predict your future from birth’. It’s an outlandish claim that raises many ethical queestions The Romans invoked Fortuna, the goddess of luck, to explain the unexplainable; fortune-tellers study tea leaves to predict the unpredictable. In Blueprint: How DNA Makes…

# Parallel lines

1.Parallel lines What is parallel lines? Two lines that are stretched into infinity and still never intersect are called coplanar lines and are said to be parallel lines. The symbol for “parallel to” is //. If we have two lines (they don’t have to be parallel) and have a third line that crosses them as…

# Parallel lines

what is heredity Heredity is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents. Through heredity, variations between individuals can accumulate and cause species to evolve by natural selection. The study of heredity in biology

# Parallel line

Parallel Lines Parallel lines are always the same distance apart (“equidistant”) and will never meet. Examiners love to throw in a question or two about them. Angles Around Parallel Lines The arrows in the above diagram show the lines are parallel. When a line crosses 2 parallel line only 2 different angles are actually formed…

# parallel line

Parallel lines Parallel lines are lines in a plane which do not intersect. Like adjacent lanes on a straight highway, two parallel lines face in the same direction, continuing on and on and never meeting each other. In the figure in  below, the two lines AB  and CD are parallel. The symbol for parallel lines is ∥, so we can say…

# Parallel line and Perpendicular lines

Perpendicular lines and Parallel lines Perpendicular lines are lines that intersect at a right (90 degrees) angle. Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect. Let’s  draw Perpendicular lines and  Parallel lines. FIRST : Draw Perpendicular lines Use a set square to draw a line that is…
