seen trucks out spreading a mixture of sand and salt on the streets after a snowfall to help deice the road. Do we sometimes dump ice cubes into a drink to help keep cool on a hot summer day? Have we ever watched the ice cubes melt and wondered how we could make them melt more slowly—or even faster? In this science activity we will get to try some different‚ common household substances to try and answer this question: What will help a solid ice cube turn into a liquid puddle the fastest? This basic chemistry project can give we some clues

Therefore because of this the political divisions increased‚ and by the end of the war the polarisation of German politics was explicit. Despite the demonstrations against the war held on the 28th and 29th of July in Berlin with crows

4.I believe that our observations are repressentative of cell division taking place in the oinon root tip. Firstly‚ this is because our numbers of the number of cells in each phase of mitosis are similar to the rest of the groups‚ so we can assume our results are most likely correct. We can also assume our calculations are right because we know that Interphase is the most active phase in the process of cell divison‚ which would agree with our calculations since we assume that approxiamtly 93% of

The division of labour is the specialization of certain tasks performed by labourers. According to Smith if a labourer specializes on a certain task‚ productivity will increased which benefits the factory system. Smith states three reasons as to why the division of labour is important to the production process: it increases dexterity‚ saves time‚ and it inspires new technology and

formed in order for an organism (whether a plant or animal) to be created. That becomes possible through cell division. Cell division happens when all of the DNA of a cell is replicated completely and then that complete replication (called a genome) is separated‚ breaking apart into two daughter cells that are identical to the original cell (Erster 3-4). There are different kinds of division depending on the type of cell involved (Erster 25). However‚ regardless of the type‚ all go through what are
