New problem. Suppose we have two positively charged particles a distance of 2 m apart from each other. Particle 1 has a charge of 3 C and particle 2 has a charge of 1.3 x 10^3 C. What
amount of electrostatic force exists between these two particles?
8.7 x 10^12 N
3.51 x 10^13 N
1.3 x 10^3 N

During crossing-over, a. genetic material is exchanged between nonsister chromatids, resulting in new combinations of alleles. b. nonsister chromatids from each homologous chromosome of a tetrad are exchanged, resulting in new combinations of alleles. c. one homologous chromosome of a tetrad is exchanged with another tetrad, resulting in new combinations of alleles. d. sister chromatids from each homologous chromosome of a tetrad are exchanged, resulting in new combinations of alleles. e. genetic material is exchanged between sister chromatids, resulting in new combinations of alleles.
