General Biology In Class Quiz - Chapter 5 10 points 1. Explain the difference between chromatin‚ chromosome‚ nucleosome and histones. Chromatin- is the combination of DNA‚ histone‚ and other proteins that make up chromosomes. Chromosome- is minimally very long continuous piece of DNA which contains many genes regulatory elements and other intervening nucleotide sequences. Nucleosome- is considered to be one of the most stable particles in the DNA that helps in the compacting and transcripting

because if they had many then they would lose lots of water (by transpiration). Leafs must grow the correct amount of stoma (for gas exchange/water loss) to the light levels in an area (even if they are shaded) this gives them a balance. Method: 1. Obtain two leaves from a shrub‚ (One from the centre and one from the outer area) 2. Paint a thick patch of clear nail polish on each of the leaves surfaces (lower/upper epidermis) being studied. (Make a patch at least one square centimetre. 3. Allow
