The muscular system. The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction. Exceptions to this are the action of cilia, the flagellum on sperm cells, and amoeboid movement of some white blood cells. The muscular system in vertebrates consists of three different types of muscles: cardiac, skeletal and smooth.
Welfare Statistics by Race, State and Payment. There are approximately 12.8 million Americans on welfare, accounting for 4.1% of the US population. An estimated $131.9 billion is spent by the government on welfare each year. The following percentages are recipients of welfare based on race. â¢ White â 38.8%.
Say we lived in a state with 100 whites and 10 blacks. Let's then say a quarter (25) of the whites are on welfare. Lets also say ALL (all 10 of them) the blacks are on welfare. 25 whites and 10 blacks are being supported by the working 75 whites. Technically, that's more whites on welfare than blacks. If you look at the population statistics though, it's only a minority of whites but the vast majority of blacks.
