Where and when would you expect to find dividing cells in the body of a multicellular organism?
Cells dividion occurs in all body cells except neuronal cells and the dividind cells cand be found in every organ of the body in a multicellular organism. cells division occurs to replace old, dead, or damaged cells. cells are also dividing to grow the living things. When any organism grows in size, weight and age, its beacuse the signals it is getting from the body for the cell division. Cell division is a continuos process. It always happens due to internal or external signals.

Where in the body would you expect to find the enzyme aromatase. A. In neurons that are converting estrogen into testosterone. B. In ovaries that are producing high amounts of estrogen. C. In the cerebellum controlling sexually dimorphic movement patterns. D. In the olfactory cells specialized to control libido.
Virtually every multicellular organism, including you, goes from a single-celled fertilized egg to a large, multicellular organism. How does mitosis explain this process? Is all growth through mitosis? If every cell in your body is a copy of that original fertilized egg, how is it that some cells are so different than other cells? What are some examples of differentiated cells, and how does mitosis help explain their differences?
No spacing Heading 1 Heading 2 Title 7. Where in the body would you find a simple cuboidal epithelium? (1) 8. What anatomical feature is found in an exocrine gland that is lacking in an endocrine gland? (1) 9. The connective tissue underlying the epidermis would be classified as: (1) a. Dense regular b. Dense irregular C. Loose d. Cartilage e. None of the above 10. What feature is common to all forms of connective tissue? (1) 11. Explain how...
in what type of cells would you expect to find a large amount of smooth endoplasmic reticulum?
how would the rates of exocytosis and pinocytosis differ between cells that aren't dividing and cells that are constantly dividing ?
In some organisms, such as the multicellular green algae Ulothrix, the zygote is the only diplodce" the life cycle, all others are haploid. While Ulothrix can reproduce sexually it can also reproduce asexually. One of the cells in a multicellular stage of the life cycle divides to produce free swimming cells called zoospores which germinate and grow into another multicellular body. 15a. Think about Ulothrix, In this organism where you know the only diploid cell is the zygote which of...
Would you expect the elemental composition of Earth's crust to be the same as that of the human body? How does high temperature affect protein structure? When an organism is exposed to high temperature, it often makes a special class of molecular chaperones called heat shock proteins. How do you think these proteins work?
As an animal’s body size increases, the number of cells in the organism also increases. Why must the number of cells increase in order to increase body size? Why can’t there simply be the same number of cells, each with larger volume? All animals begin life as a single-celled zygote, but become multicellular through development. The increase in number of cells must come from an increased number of mitotic divisions and this in turn may increase the risk of developing...
If you labeled a healthy population of actively dividing cells with a DNA stain like propidium iodide (PI) or DAPI diagram the expected results for a graph of cell number versus DNA stain fluorescence intensity. Relate the peaks on the graph to the various portions of the cell cycle and include a separate peak to show where apoptotic cells would fall relative to healthy cells in the population. Please answer in detail and show the graph clear. Thank you very...
