I believe that the Loose uncoiled chromosomes are actually DNA in the form of Chromatin. Genes are made up of chromosomes and direct the formation of a specific characteristic DNA and genes are the same thing. Chromosomes contain 100 to 100 of genes in one very long strand of DNA. The DNA is coiled around proteins that are called histones. The DNA seems to form a bigger part of the chromosome than the histone and since the DNA consists of genes, then half of the chromosomes is genes.
The relationship between a leech and a crocodile is an example of parasitism, as the leech feeds on the alligator's blood.
The answer to this question would be: <span>by converting glucose to glycogen.
Brain cells only able to use energy from glucose, so if the body glucose level is too low the brain cells can't work as it doesn't get any energy/food. When glucose level is decreased, the liver will start to convert glycogen into glucose to keep the glucose level.</span>
