Given what we know, we can confirm that the scenario that best demonstrates the mechanism of apoptosis is 1, "An immune cell Self-destructs once it is no longer needed by the immune system".
<h3>What is apoptosis?</h3>
- This is what we describe as a programmed cellular death.
- This means that when a cell is no longer needed or is damaged or old, it is programmed to automatically self-destruct in order to make room for new cells.
- This is also an effective way to reuse the resources the cell contained.
- When this mechanism fails, it can often lead to the formation of cancer.
Therefore, we can confirm that option 1 which states "An immune cell Self-destructs once it is no longer needed by the immune system" is the best description available of apoptosis given its definition as a programmed cellular death.

Answer:
In which stage of mitosis is it? Metaphase
What are the structures visible in green and blue fluorescence? green show Microtubules and blue Chromosome.
Explanation:
The chromosomes align themselves along the equatorial plane of the spindle. They are suspended by microtubules.
Answer:
46 chromosomes
Explanation:
Humans are diploid organisms i.e. they contain two sets of chromosomes (each set from each parent). Each set is 23 chromosomes, hence, two sets will be 23 pairs or 46 chromosomes. This means that each somatic/body cell will contain 46 individual chromosomes.
According to this question, DNA was extracted from a cheek cell. If one could magnify the extracted material, there would be 46 individual chromosomes from each of these cheek cells, considering that cheek cell is a somatic cell.

Radio waves cover a huge band of frequencies, and their wavelengths vary from tens of centimeters for high-frequency waves to hundreds of meters (the length of an athletics track) for lower-frequency ones. That's simply because any electromagnetic wave longer than a microwave is called a radio wave.</span><span>Microwaves: Obviously used for cooking in microwave ovens, but also for transmitting information in radar equipment. Microwaves are like short-wavelength radio waves. Typical size: 15cm (the length of a pencil).</span><span>Infrared: Just beyond the reddest light we can see, with a slightly shorter frequency, there's a kind of invisible "hot light" called infrared. Although we can't see it, we can feel it warming our skin when it hits our face—it's what we think of as radiated heat. If, like rattlesnakes, we could see infrared radiation, it would be a bit like having night-vision lenses built into our heads. Typical size: 0.01mm (the length of a cell).</span><span>Visible light: The light we can actually see is just a tiny slice in the middle of the spectrum.</span><span>Ultraviolet: This is a kind of blue-ish light just beyond the highest-frequency violet light our eyes can detect. The Sun transmits powerful ultraviolet radiation that we can't see: that's why you can get sunburned even when you're swimming in the sea or on cloudy days—and why sunscreen is so important. Typical size: 500 nanometers (the width of a typical bacteria).</span><span>X rays: A very useful type of high-energy wave widely used in medicine and security. Find out more in our main article on X rays. Typical size: 0.1 nanometers (the width of an atom).</span><span>Gamma rays: These are the most energetic and dangerous form of electromagnetic waves. Gamma rays are a type of harmful radiation. Typical size: 0.000001 nanometers (the width of an atomic nucleus).</span></span>
