Answer:
The process in cell division by which the nucleus divides, typically consisting of four stages, prophase, metaphase, anaphase, and telophase, and normally resulting in two new nuclei, each of which contains a complete copy of the parental chromosomes.
almost any living organisms like animals and humans. Im not so sure about plants though. happy studying! :)
Answer:The predicted population of brain coral in a reef covering 120m² is ; ≈ 40
First step : Calculate the value of the default population density
Population density = population size (dive 1) / total area
= 4 / 12 = 0.33
Total area ;
∑ Area of each reef quadrant = length * width = 2 * 2 = 4m²
∴ Total area = 4 + 4 + 4 = 12m².
Final step : Determine the value of the predicted population of brain coral
Population density = ( predicted population ) / predicted area
0.33 = ( pp ) / 120m²
∴ Predicted population ( pp ) = 0.33 * 120
= 39.6 ≈ 40 brain corals
Hence we can conclude that the predicted population of brain coral is 40

Yes it is true you are very smart :) let me know if this is helpful
Explanation:
1.Structure of virus- Schleiden and Schwann could not explain the structure and functioning of virus cell. They said that the function of body is coordinated function of cell which is not true in the case of virus because it only starts it's functioning when hosted by bacterial, plant or animal cell.
2.Prokaryotic cells- The cell theory do not holds true in the case of Pk cells because they do not have any well defined nucleus.
3.Multinucleate condition- The cell theory says that each cell have A NUCLEUS, but there are certain cells like tapetal cells that are coenocytic.
4.Cells without nucleus- Acc to cell theory there should be a nucleus in every cell, but human RBCs, sieve tubes of angiosperm are some of the cells lacking nucleus.
