Babies with very low or very high birth weight are less likely to survive. observe a graph of the data. a graph entitled percentage of babies born at different weights has weight in pounds on the horizontal axis, and percentage on the vertical axis. a small percentage of babies are born at the low and higher birth weights, and a greater amount are around 7 to 8 pounds. which statement is a valid claim that could be made using the data in the graph? directional selection is occurring because the graph favors an extreme. stabilizing selection is occurring because the average is favored. disruptive selection is occurring because the two extremes are favored. biodiversity selection is occurring because of the greater variation.

What causes the formation of ocean currents?

Newton's law of cooling states that the rate of change in the temperature t(t) of a body is proportional to the difference between the temperature of the medium m(t) and the temperature of the body. that is, startfraction dt over dt endfraction equals upper k left bracket upper m left parenthesis t right parenthesis minus upper t left parenthesis t right parenthesis right bracket , where k is a constant. let kequals0.04 left parenthesis min right parenthesis superscript negative 1 and the temperature of the medium be constant, m(t) font size decreased by 3 equivalent font size decreased by 3 294 kelvins. if the body is initially at 369 kelvins, use euler's method with hequals0.1 min to approximate the temperature of the body after (a) 30 minutes and (b) 60 minutes.

Each line (unit) on the horizontal axis represents: 5 years 10 years 20 years all of the above
