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.)
Ribosomes are the sites of protein synthesis, where RNA is translated into protein. When cells need large numbers of proteins, they must first build numerous ribosomes.Because protein synthesis is so important to cells, there are large numbers of ribosomes found throughout cells often numbering in the hundreds or thousands.In eukaryotic cells, three of the four ribosomal RNA strands are synthesized in the nucleolus, a structure in the nucleus. think its when it binds the mRNA together To put it in two sentences: 1. Ribosomes are the place where Protein Synthesis takes place. 2. In the Ribosome, the mRNA, tRNA, â¦ and Amino Acids meet to form a Protein. 3. The Ribosome is the main organizing center for Protein Synthesis.
