Answer:
All living things are made of cells
Cells form from previously existing cells
Explanation:
According to the Cell Theory, all forms of life are composed of one or more cells, whereby cells are the fundamental building blocks in all living organisms. All cells are composed of inorganic molecules (e.g., water) and carbon-based organic molecules (e.g., carbohydrates, lipids, nucleic acids, etc). All the new cells arise from the division of pre-existing cells. Louis Pasteur showed cells would only grow in broth if they are exposed to air (oxygen), thus refuting the idea of spontaneous generation. In multicellular eukaryotic organisms, these cells can be organized in tissues, organs and organ systems.

Answer:
8,324,608 chromosome combinations
Explanation:
During meiosis, chromosomes separate independently so that only one chromosome came from the father and the other homologous chromosome came from the mother. This process of independent assortment produces a huge amount of possible combinations in the diploid zygote cell. In humans, the haploid number of chromosomes is n = 23, thereby there are 2²³ = 8,324,608 chromosome combinations. Thus, the independent assortment of chromosomes during meiosis is a key factor that contributes to genetic variation in the offspring.
