Mitosis and cytoplasmic division function in ___. a. asexual reproduction of single-celled prokaryotes b. development and tissue repair in multicelled species c. sexual reproduction in plants and animals 1. Why are cells from a blastula used to examine mitosis? \\ 2. How fast do you think...
How are epithelial cells adapted to their function? How is cell differentiation different in plants and animals? Why are muscle cells different from blood cells? How do cells form tissues? How do hormones reach target cells? How is mitosis the same for animal and plant cells? How are endothel...
And, as in animals, the mechanisms that restrict the proliferation of somatic cells in plants can fail, leading to tumours. There are intriguing similarities in tumorigenesis between plants and animals, including the involvement of the retinoblastoma pathway as well as overlap with mechanisms that ...
Some animals, such as the sea cucumbers, even have yellow blood. What could make blood yellow? The yellow coloration is due to a high concentration of the yellow vanadium-based pigment, vanabin. Unlike hemoglobin and hemocyanin, vanabin does not seem to be involved in oxygen transport. Which...
Although ancient in biology, and particularly in zoology, the “species problem” has been renewed in the recent decades, in part because of the development of cladistic thinking, and in part through the discovery in animals of many unexpected evolutionary situations and “strange species”, often...

This coincides well with the fact that Chk-1 inhibition sensitizes colon carcinoma HCT116 cells to lidamycin through abrogation of a G2/M checkpoint and induction of a caspase-2-dependent apoptotic pathway. In addition, a distinct mechanism of caspase-2 inhibition during mitosis has been ...

How is meiosis similar to mitosis? a. Both produce daughter cells that are genetically identical. b. Both produce daughter cells that are genetically different. c. Both occur in human, other animals, and plants. d. Both occur asexually. ...
How are somatic cells in animals and plants categorized? Why do cells go through cell differentiation? According to the cell theory, where do cells come from? How do Schwann cells form the myelin sheath? What is the function of columnar epithelial cells?
