2. Mendel's Principle of Segregation (In the formation of gametes, the paired hereditary determinants (genes) separate (segregate) in such a way that each gamete is equally likely to contain either member of a pair) was later supported by microscopic studies of chromosome movement during meiosis. Which of the following symbolic representations best depicts the Principle of Segregation? A. AaBb cells ---------→ roughly 50% Aa gametes and 50% Bb gametes B. Aa cells ------------→ 100% Aa gametes C. AaBb cells -------->...

Classify the characteristics of the three types of muscles. Some labels may be used more than once. Cardiac Muscle Skeletal Muscle Smooth Muscle Characteristics: Composed of spindle- shaped cells Composed of branching, striated cells Functions in voluntary body movements Found only in the walls of the heart Found in muscles attached to the body's bones Involuntary muscle Named for cells that lack striation Also called voluntary muscle Individual cells have multiple nuclei Individual cells have a single nucleus
