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: Option (1)
Explanation:
The extinction event played an important role in the creation of new diverse life forms on earth. After an extinction event, both globally and locally, more than 75% of animal species gets vanish and the only those highly resistant life supporting organisms survive and with due course of time, they undergoes evolution, thereby bringing changes to the existing life forms. This is how they initiates and helps in the increasing species diversity.
Thus, the correct answer is option (1).
Answer;
-A motor protein called dynein
Cilia and flagella bend because of a motor protein called dynein.
Explanation;
-Both prokaryotic and eukaryotic cells contain structures known as cilia and flagella. These extensions from the cell surface aid in cell movement. They also help to move substances around cells and direct the flow of substances along tracts.
-Cilia and flagella are formed from specialized groupings of microtubules called basal bodies. If the protrusions are short and numerous they are termed cilia. If they are longer and less numerous they are termed flagella.
