Answer:

The structure and function of the chromosome are different in both the prokaryotic chromosome and eukaryotic chromosome. They differ in their size as the genetic information they carry is different from one another.

Eukaryotic chromosome have a different shape from the prokaryotic chromosome as the bacterial chromosome is circular and less complex due to no histone found in prokaryotes as we see in the eukaryotic chromosome. SIze of the bacterial or prokaryotic chromosome is also small and not found in condensed form as these cells carry less genetic information than eukaryotic cells.

Why would it be important to know the possible genotypic and phenotypic ratios of different genetic crosses?
OleMash [197]
It’s important to know the possible genotypic and phenotypic ratios of different genetic crosses because the the phenotype shows what the offspring will physically look like what the genotype is what genes the offspring carries. phenotype doesn’t always show what alleles the offspring carries because if the offspring is heterozygous for the gene only the dominant allele shows and the recessive allele won’t be visible. the genotype can see what alleles the offspring carries, both dominant and recessive. knowing the genotype helps to know what alleles are passed on. if one of the parents have a genetic mutation that is passed on, the phenotype helps see what ration of offsprings will have the mutation visible and the genotype will help see what ratio of offsprings will pass on the allele for the mutation

What happens if you drop some type of liquid on a cable such as a phone charger? Can you get hurt? Can you still use it?
ipn [44]

It really just depends. If the liquid got in any crevices it might not work. If it wasn't plugged in, no you cannot get hurt. But I've had chargers that I spilled water on and they still work fine, but again, it depends. Like if there's a tear in the cord that liquid got in, then no it probably won't work anymore.
