Answer:
The correct answer will be option-A
Explanation:
Colchicine is the drug that prevents the assembly of the mitotic spindles which halts or stops the cell cycle.
The colchicine acts by inhibiting the microtubule polymerization thus mitotic spindles which takes place after the condensation of the chromosomes during prophase and pre-metaphase.
This acts as checkpoint which can halt the cell cycle at the phase of chromosome condensation.
Thus, option-A is the correct answer.
Answer:
This process is called phosphorylation(addition of phosphate) and since the energy comes from photons, this process is termed as photophosphorylation. Yes, the same NADPH donates its hydrogen to combine with CO2 to form glucose (C6H12O6) to become NADP again.
Explanation:
The electromagnetic radiation with wavelengths between 380 nm and 700 nm is visible light (option D).
<h3>What is electromagnetic spectrum?</h3>
Electromagnetic spectrum is the entire range of wavelengths of all known electromagnetic radiations extending from gamma rays through visible light, infrared, and radio waves, to X-rays.
The electromagnetic spectrum is made up of the following radiations separated by differing ranges of wavelengths;
- ultraviolet (400 nm - 1 nm)
- visible: (750 nm - 400 nm)
- near-infrared: (2.5 μm - 750 nm)
- infrared: (25 μm - 2.5 μm)
- microwaves : (1 mm - 25 μm)
- radio waves : > 1 mm
Therefore, the electromagnetic radiation with wavelengths between 380 nm and 700 nm is visible light (option D).

I'm guessing here but, some advantages are, embryonic stem cells are very effective at repairing damaged tissues, but they are difficult to obtain, and either have to be obtained from umbillical chords of babies, or from fertilized embryos from a laboratory. So I am guessing they would be expensive/difficult to source because you would either have to collect umbillical chords from babies, or have to purchase eggs from women, and they are ethically questionable to use because you are essentially making potentially viable embryos and then killing them. Hope this helps.
Explanation:
The correct answer is D. Nuclei
During this process, multiple nuclei are created and they all exist at the same time until the cytoplasm separates and starts forming new cells, which is when the nuclei enter these new cells and separate, forming thus new cells.
