Climate Zones Objectives: 1. Describe Earth's major climate zones. 2. Explain how climate zones are characterized. Notes: According to the three cell convection model of each hemisphere the Earth neatly separates itself into three distinct climate zones; the polar, temperate, and the tropical zones.limate Zones Objectives: 1.

The nucleus is a large roundish organelle. It is bounded by a double membrane which has numerous pores. Inside the nucleus are chromosomes and a dark region called a nucleolus which makes ribosomes. (Ribosomes are necessary for protein synthesis.)
    The organelle which is the site of protein synthesis for the cell is the ribosome. DNA in the nucleus has the code for building protein, mRNA picks up the code and â¦ brings it to the ribosome where the code is translated into a sequence of amino acids that makes up specific proteins.1 person found this useful.Answered.or the purpose of this questi â¦ on the actual synthesis occurs at the Ribosomes as these are small multiple part cellular machines that interpret (Translate) RNA into the final proteins. This question implies a bound site however and the Ribosomes can be free moving in the cytoplasm of the cell.
