Answer the following question given this paragraph: DNA replicates in the S phase of interphase. After replication, the chromosomes are composed of two linked sister chromatids. When fully compact, the pairs of identically packed chromosomes are bound to each other by cohesin proteins. The connection between the sister chromatids is closest in a region called the centromere. The conjoined sister chromatids, with a diameter of about 1 m, are visible under a light microscope. The centromeric region is highly condensed and thus will appear as a constricted area. Q: What replicates in the s phase of interphase, resulting in chromosomes composed of two linked sister chromatids? Choices: - protein - hormones - RNA - dna A:
dna

Ques:Answer the following question given this paragraph: Did you ever rub an inflated balloon against your hair? You can see what happens in Figure below . Friction between the rubber of the balloon and the baby's hair results in electrons from the hair "rubbing off" onto the balloon. That's because rubber attracts electrons more strongly than hair does. After the transfer of electrons, the balloon becomes negatively charged and the hair becomes positively charged. As a result, the individual hairs repel each other and the balloon and the hair attract each other. Electrons are transferred in this way whenever there is friction between materials that differ in their ability to give up or accept electrons. Q: When a balloon is rubbed against hair, they attract each other because of a difference in what? Choices: - Force - Friction - actions - charges A:

Ans:charges
