Answer:
c. inner cell mass
Explanation:
The inner cell mass of the blastocyst forms the embryo while the outer layer, the trophoblast forms the placenta.
Answer: When your vocal cords produce a louder sound, it is known that the vibrating vocal cords produce sound waves.
Explanation:
Explanation:
Mitosis is the nuclear division followed by cytokinesis, which leads to the production of two daughter cells.
<u>It includes the following phases -
</u>
1. Interphase - In this process the Cell actively metabolizes and prepare itself for the process of mitosis and the Chromosomes are not clearly discerned .
2. Prophase - In this phase , the Chromatin gets to condense and can be visualized under a light microscope and Nucleolus gets disappeared , Centrioles begins to move to opposite ends of the cell .
3. Metaphase - In this phase the Spindle fibers gets align the chromosome along the middle of the nucleus of the cell thereby creating a metaphase plate .
4. Anaphase - In this phase , the chromosomes which got paired up gets separate at the kinetochores and move to the opposite directions of the cell , the Spindle microtubules and physical interaction among polar microtubules is responsible for kinetochore movement.
5. Telophase - In this phase , the Chromatids completely move to the opposite poles of the cell , and new membranes start forming around the daughter nuclei and the Chromosomes disperse and become invisible. Cytokinesis starts.
6. Cytokinesis - In this final process the Actin fiber ring around the center of the cell contracts and create the cell into two daughter cells.
