Answer:
1. meiosis 2. meiosis 3. meiosis 4. Binary fission 5. mitosis and meiosis 6. mitosis 7. meiosis 8. mitosis and meiosis 9. mitosis 10. Binary fission 11. meiosis.
Explanation:
The process of mitosis ad meiosis is a type of cell division that occurs in eukaryotes. The type of cell division in prokaryotes including bacteria is the binary division in that they do not have nucleus.
Mitosis is a type of division that produces identical diploid cells as the parent diploid cell. It involves only one division and involved in replacement of damaged tissue and for growth and development.
Meiosis is a type of cell division that produces unique daughter cells with genetic variation as a result of genetic recombination that occurs in the crossing over event in the interphase 1 of meiosis. This type of division involves two division (meiosis II and II) and also produces haploid cells. The parent cell is a germ line cell that was first diploid and then undergoes this form division producing haploid cells to be transferred to offspring.

Answer:
Both facilitated diffusion and active transport are selective processes. Only selective molecules are allowed to cross the membrane. They utilize carrier proteins to move across the membrane.
Explanation:
Diffusion is the process by which molecules move across a membrane respective of the concentration gradient. The plasma membrane is a <em>selectively permeable membrane</em> which allows specific molecules to move across the concentration gradient.
Molecules migrate from a region of higher concentration to a lower concentration in case of diffusion. It can be classified into simple diffusion and facilitated diffusion. These are examples of <em>passive transport</em>.
In facilitated diffusion molecules move across the concentration gradient with the help of <em>carrier proteins or channel proteins</em>. The carrier proteins bind to the molecule which has to be transported and change conformation to allow it to cross the membrane. For example glucose molecule is carried across through <em>GLUT transporter</em>. <em>Channel proteins</em> open a channel inside the membrane and molecules get transported across the gradient.
Active transport carries molecules against the concentration gradient with the assist of energy. ATP hydrolysis is utilized to generate energy. As a result of active transport, the molecules are aggregated on one side of the membrane.
