Anatomy
Major cavities of the body and their organs:
Our body is made up of solid structures and many cavities. The organs are packed in these cavities and they fill these cavities. The major cavities in our body are: the ventral cavity, which is surrounded by the rib cage and the abdominal musculature and dorsal cavity, which is surrounded by the bones of the skull and vertebral column.

Significance and Process of Protein synthesis:
The genetic material of life is DNA. It is present in all the organisms on the earth and it has genetic information, which the organism uses for producing the protein essential for life. The DNA, whether it is in prokaryotic or eukaryotic cells, it is in the iconic form of the double helix, and it uses the same common genetic code that permits it to be converted to proteins. The procedure of forming proteins from DNA, which is known as transcription and translation are the same in all organisms. DNA is transcribed into RNA, which is then translated to amino acid chain of polypeptide. (Lesson 1: From Genes to Proteins)
3. Glycolysis and ATP:
The transformation of food to energy by the energy molecule of the cell called Adenosine Tri Phosphate - ATP is called Glycolysis. ATP is a nucleotide. Glycolysis makes use of the...
Glycolysis also forms two three-carbon compounds called pyruvate that still has energy. Glycolysis ends in the addition of two hydrogens onto the energy carrier nicotinamide adenine dinucleotide - NAD to form NADH. Though glycolysis permits the formation of four ATP, two ATP are used in the process. This results in a net profit of two ATP from the process of Glycolysis. Glycolysis does not need molecular oxygen, as it is an anaerobic process. (How organisms convert food to energy)
4. Types of Muscle:
There are three types of muscles. They are: Cardiac muscle, which is represented by centrally located nuclei, and muscle fibers made up of many cells connected by intercelated discs; skeletal muscle represented by no nuclei located within the tissue, but are pushed to the sides; Smooth muscle, which has varied sizes of nuclei, but is not highly structured.

5. Human Skin Color:
In humans, the formation of the skin coloring agent melanin is regulated by two pairs of genes. It can be designated as Aa and Bb, in which the capital letter stands for dominant genes and the small letters the recessive genes. A and B. produce melanin very well, and a and b produce lesser levels. For…
