16. what are the substances that constitute the chromatin? what is the difference between chromatin and chromosome?

Tchromatins make up chromosomes. Chromatins are just a combination of DNA, histones(a type of proteins) and RNA. Strands of DNA are considered as chromatins and when these strands combine, this forms the chromosome. Chromatin is untangled and unfolded DNA, while chromosome is condensed DNA. The chromatin, dispersed in the nucleus, is a set of filamentous DNA molecules associated to nuclear proteins called histones. Each DNA filament is a double helix of DNA and thus a chromosome.  

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
