Not So Ancient After All Trees Recycled for Navy, Parks Restoration Projects By Rich McManus
By Sharon Ricks
In a biology laboratory 3 miles from Spingarn High School, 10th grader Marvin
Bethea watches as a sharp lancet dives into his middle finger, and a drop of blood
appears. Under a binocular compound microscope, erythrocytes, leukocytes, and
neutrophils emerge 400 times their normal size. Marvin counts the odd doughnut
shapes, and with the help of an instructor learns why some cells have a nucleus
and others don't. |
