Answer:
can we chat yes or no I think I can help with that
Because of their relatively simple genetic structure when compared to other organisms. Not to mention, they breed in extremely high numbers which is great for scientists looking to do many trials, as most are. Their life cycle is also very short which means we can observe their entire life span and witness the effects of testing at all stages.
Karyotype refers to the visual appearance and number of the chromosomes in the cell nuclei of a species or an organism. It is known that there are 46 chromosomes in a usual nucleus of a human that comprises 23 pairs of chromosomes. Of these, one pair is considered as sex chromosomes.
In females, the sex chromosomes are XX, while in males, the sex chromosomes are XY. So, the karyotype of a human male would comprise 22 pairs of autosomal chromosomes, an X chromosome, and a Y chromosome.
Well it depend on what type and also what they are trying to do
The dual nature of light is the property of light where it has both wave and particle properties.
The wavelength properties of light are such that light behaves as a set of electromagnetic waves that have different wavelengths.
The electromagnetic spectrum is the whole range of frequencies and wavelengths of electromagnetic waves.
<h3>What is the wave-particle dual nature of light?</h3>
The wave-particle dual nature of light is the property of light where it has wave-like properties such as reflection, refraction, diffraction, etc., and also has particle properties such as the photoelectric effect.
The wavelength of light is the distance between successive points in the wave.
The whole range of frequencies and wavelengths of light gives the electromagnetic spectrum.
