Pairs of identical chromatids are attached to each oher at
an area called the
• A. centriole
• B. centromere
• C. Spindle
• D. chromosome

 B) Centromere

I recommend looking at the wikipedia page for Chromatid. They show a diagram where the centromere is, which is basically where the chromosomes glue together more or less.

The scientific name or the binomial nomenclature has a number of advantages over using the common names. 1. Organise and classify - the organism can be easily categorised, this really helps making it easier to understand the characteristics of a specific organism in an organised chart.
