How red blood cells survive without nucleus?
becas their life span is less
How can you stop being afraid of mice?
you need to hold the a mouse and be around a mouse. the more time you spend with them the less afraid you will be
What are animal eye rods used for?
There are two types of photoreceptors in the retina, cone cells and rod cells. There are 92 million rod cells in a retina. Rod cells function in less intense light and are important for peripheral vision and night vision.
What cells in the retina are primarily responsible for night vision as opposed to day vision?
Rod cells are primarily responsible for night vision, as they are more sensitive to low light levels and can detect dim light. Cone cells, on the other hand, are responsible for day vision and are less sensitive to light but can detect color and high levels of light.
Does hamsters really sleep for a long time?
Yes, hamsters are crepuscular creatures, meaning they are more active during dawn and dusk. However, they do spend a significant amount of time sleeping during the day and night, with an average sleep time of around 14-16 hours per day.
Where are rapidly reproduced cell found?
The reason why cancer cells reproduce more rapidly other then regular cells is because they spend less time in interphase.
Why do cells spend the greatest percentage of their cycle in interphase?
Cells spend the greatest percentage of their cycle in interphase because it is a phase of growth and preparation for cell division. During interphase, cells grow in size, replicate their DNA, and carry out normal cellular functions before entering mitosis. This ensures that the cell is in optimal condition for division.
In which phase does a cell spend less time in?
I believe this question is leaning towards the topic of Mitosis. Between each cycle of mitosis, the cells does all its cellular business during "Interphase" which is a way longer phase than Mitosis
What happens to chromatin during interphase?
During interphase, chromatin exists in a less condensed form, allowing for gene expression and DNA replication. It is loosely organized in the nucleus, ready to be transcribed into RNA for protein synthesis. This less condensed form of chromatin helps facilitate various cellular processes that occur during interphase.
In what type of cell is interphase NOT the longest part of the cell cycle?
In cancer cells, interphase is not the longest part of the cell cycle. This is because cancer cells can progress rapidly through the cell cycle, spending less time in interphase compared to normal cells.
Can chromosomes be seen only during cell division?
No, chromosomes can also be seen in non-dividing cells during interphase under a microscope. In interphase, chromosomes are less condensed and appear as long, thin, thread-like structures within the nucleus. During cell division, chromosomes condense further to become more visible as distinct structures.
Why are karyotypes prepared using cells in mitosis rather than cells in interphase explain.?
Karyotypes are prepared using cells in mitosis because chromosomes are most condensed and visible during this phase, making it easier to observe and analyze any abnormalities or mutations. In interphase, chromosomes are less condensed and more tangled, making it challenging to accurately identify and count the individual chromosomes necessary for a karyotype analysis.
Why do cells spend the most time in interphase?
Cells spend the most time in interphase because it is a period of growth and preparation for cell division. During interphase, cells replicate their DNA, increase their size, and prepare the necessary components for cell division. This ensures that when the cell eventually divides, each daughter cell receives a complete set of genetic information and the necessary organelles to function properly.
Why are individual chromosomes more difficult to see during inter phase than during mitosis?
During interphase, individual chromosomes are less condensed and more dispersed throughout the nucleus, making them harder to distinguish. In contrast, during mitosis, chromosomes are highly condensed and arranged in a more compact and visible manner. This condensed state allows for easier visualization of individual chromosomes.
Cells nucleus during interphase?
During interphase, the cell's nucleus undergoes activities such as DNA replication, transcription, and preparation for cell division. Chromatin is in a less condensed form during interphase, allowing for easier access to DNA for processes like gene expression. The nucleus also synthesizes RNA and proteins needed for cellular functions and growth.
Is it impossible to count individual chromosomes during interphase?
Yes, it is very challenging to count individual chromosomes during interphase because they are not condensed and visible as distinct units. Chromosomes are typically spread out and exist in a less condensed form during interphase, making them difficult to differentiate and count accurately.
Why chromosome observed in prophase but not in interphase?
Chromosomes are condensed and visible in prophase due to the coiling of DNA to form compact structures. In interphase, chromosomes are in their less condensed state, called chromatin, making them less visible under a microscope. This allows for gene expression and DNA replication to occur before cells enter mitosis and condense their chromosomes again.
