What else can I help you with?
What stage of the cell cycle is the nucleolus always visible?
The nucleolus is always visible during interphase, particularly during the G1, S, and G2 phases of the cell cycle. This is when the cell is actively growing and synthesizing proteins.
What is a type of cell that does divide actively?
A meristematic cell
What phase of cell division is the cell not dividing?
During the interphase stage of the cell cycle, which includes G1, S, and G2 phases, the cell is not actively dividing. Instead, it is preparing for cell division by growing and replicating its DNA. It is only during the M phase, which includes mitosis and cytokinesis, that the cell actually divides.
What what happens during interphase?
the chromosomes are duplicated.
What activities are going on in the cell during interphase?
During interphase, the cell is actively growing, carrying out its normal functions, and preparing for cell division. DNA replication occurs, resulting in each chromosome being duplicated. Additionally, organelles are also replicated during this phase.
Why does penicillin kill only actively multipling cells and lysozyme will kill cells in any stage of growth?
Penicillin inhibits transpeptidase, and enzyme that is necessary for bacterial cell wall synthesis. If a cell is not actively multiplying, then no cell wall synthesis is occurring and, therefore, penicillin does not inhibit the bacteria.
How oxygen is passed from a red blood cell to an actively respiring muscle?
The oxygen passes through a bloodvessel called artery to an actively respiring muscle cell.
Animal cells actively replicate their genetic material during?
When the cell is splitting in two. Here is the order: the cell grows to twice its size, makes a copy of its genetic material, slices itself in the middle, and finally splits into two equal cells.
What actively regulates what enters and exits the cell?
the bladder
Which cell is most actively photosynthesising?
[object Object]
If you were examining a skin cell during one complete cell cycle which phase would you never observe?
You would never observe the G0 phase. Skin cells typically do not enter the G0 phase since they are actively dividing to replenish the skin. The G0 phase is a resting phase where cells are not actively dividing.
Small cell resulting from meiosis in female animals which usually does not participate in reproduction?
The small cell resulting from meiosis in female animals is known as a polar body. It typically does not participate in reproduction and eventually degenerates or is absorbed by the body. Its main function is to ensure that the larger egg cell receives most of the cytoplasm and organelles during meiosis.
