A. cycles B. equilibrium C. change D. models E. scientific method
all these would be found in science.
Do you need specific sources on this for a paper? I️ would use easybib it is a great source to get bibliographies done quick.
Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types.
Biomolecules are organic compounds that are present as essential components of living things. There are four major biomolecules namely lipids, proteins, carbohydrates and nucleic acids. Proteins, lipids and glucose are usually used by organisms as energy sources as well as structural components among other functions in living organisms. Nucleic acids are important components that bring about heredity. In this case the appropriate molecule to be chosen by the long distance learner would be carbohydrate because it stores and may be used as a source of energy.
Answer:
1) To form a multicellular organism, a zygote must divide into 16 cells which produces ball structure called a morula. After that, morula is converted into a structure called blastula.
2) Adult stem cells are responsible for the maintenance of tissues and repair the damage tissues in the body. It is also called somatic stem tissue. It increase in number through cell division.
