In Snapdragon flowers, red flower color (R) is incompletely dominant over white flower color (r). The heterozygous plants have pink flowers. Make a Punnett Square for a pink flowered plant crossed with a red one. What are the resulting phenotype percentages?

Animal bodies (and even plant bodies for that matter) are complex enough that life couldn't exist without enzymes. enzymes are usually large, complex biological catalysts that are expensive to make. enzymes speed up the rate of chemical reactions without being used up during the reaction (they can be reused many times). they are highly specific in the reactions they regulate. knowing what enzymes are and how they function, why does this explain why complex life forms could not exist if there were no enzymes.

Organisms are classified, or grouped into categories, based on similarities in their characteristics and/or evolutionary relationships. the study of how organisms are classified is known as
