• B) The pH of the solution is equal to the pK_a of the conjugate base.

Definitions:

Sister Chromatids

Identical copies of a chromosome, connected by a centromere, that are created during DNA replication and separated during cell division.

Anaphase II

A phase of meiosis II where sister chromatids are separated and moved to opposite poles of the cell, leading to the formation of four haploid daughter cells.

Metaphase II

A phase of meiosis II where the chromosomes align at the metaphase plate, similar to metaphase in mitosis, but this process occurs in a haploid set of chromosomes.

Meiosis

Process in which a 2n cell undergoes two successive nuclear divisions (meiosis I and meiosis II), potentially producing four n nuclei; leads to the formation of gametes in animals and spores in plants.
