Biophysicists use an arrangement of laser beams called optical tweezers to manipulate microscopic objects. In a particular experiment, optical tweezers exerting a force of0.373 pN were used to stretch a DNA molecule by 2.30 μm. What was the spring constant of the DNA?Express your answer with the appropriate units.

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.
