Answer: D. All living cells come from other living cells.

Explanation:

A is incorrect because organisms like bacteria and amoebas are unicellular, or have 1 cell.

B is incorrect because cells are specialized: nerve cells and muscle cells do not share the same function.

C is incorrect because inanimate objects are not alive and do not have cells.

D is correct because cells reproduce by mitosis, creating copies of themselves.

Answer:

Kinases would stop working too.

Explanation:

Cells work constantly to maintain homeostasis or equilibrium within themselves. One of the mechanisms used for this purpose is feedback. As mentioned in the question, kinases put phosphates on proteins, and then, phosphatases take them off. Therefore, for phosphatases to work, kinases must be working at the same pace. By inhibiting the phosphatases the number of phosphate-proteins will be too high. This can be perceived by the kinases and they will automatically stop working since there's an excess of product. That process is called feedback.

Which phase of mitosis is shown in the diagram
Lorico [155]

If there's this picture in the question, the right answer is metaphase.

A metaphase qualifies a phase of meiosis or mitosis (following prophase and preceding anaphase) during which chromosomes, or at least kinetochores, align with the equatorial plate of the spindle. At this stage, chromosomes are at their maximum condensation and karyotypes are usually established. In the first division of meiosis, the metaphase represents the phase during which meiotic analysis is usually accomplished.
