Document Summary
The biosphere: abiotic factors (non-living) include sunlight, temperature, humidity, wind speed, cloud cover, and rainfall. These factors contribute to a region"s climate, the weather conditions prevailing over an extended period of time. Seasonality: weather through the year: the earth"s tilt of 23. 50 from the perpendicular to the plane on which it orbits the sun produces seasonal variation in the duration and intensity of incoming solar radiation. Biotic factors: for example, competition among organisms, parasitism (a symbiotic relationship in which one organisms benefits at the expense of another), or mutualism, in which both organisms benefit. They still contain trace amounts of chlorophyll a but only one has both chlorophyll a and b. 2: existence of discrete variants of a character is called a polymorphism, we describe phenotypic polymorphism quantitatively by calculating the percentage or frequency of each trait. The hardy-weinberg principle is a null model that defines how. Diploidy can hide recessive alleles from the action of natural.
