Hello. It is not possible to make a report of your class in the laboratory, without having attended that class. For this reason, I will show you how this report can be written. I hope it helps you.
You should start your report with an introduction. This will be a short paragraph, where you will present the laboratory where the class was held, the time and date. Then you will give a brief presentation of what was observed during that class.
In a second paragraph, you will start by explaining better, all the elements of the class, what was discussed and what equipment was used. You should also show all the activities done in the laboratory in the most detailed way possible. This paragraph can be divided into more than one paragraph, if you have a lot of information to tell.
Finally, you should end the report with a conclusion, showing what you have learned from this experience.

Spines of thoracic vertebrae are longer and are directed downwards while that of the lumbar vertebrae project towards the posterior region. the sacrum is present below the lumbar region and consists of five fused sacral vertebrae. The last category of spine is coccyx. It has four fused coccygeal vertebrae.

Released energy of catabolism (in a form of ATP) is used for the maintenance and growth of cells. Examples of catabolic processes are glycolysis, the citric acid cycle or degradation of macromolecules: proteins into amino acids, lipids into free fatty acids...
