There were multiple parts to this experiment that were introduced together. In the first part of the experiment‚ we used a cup and a coin with both a heads and tails side‚ shook the coin‚ and looked at the side in which the coin landed on. After conducting these tests 20 times‚ we recorded which side that the coin landed on each time. In our results‚ we saw that the coin landed on heads 11 times and it landed on the tails side 9 times. We originally hypothesized that it would be an even mix between

placed a branch from one tree and place it on another one; it is now possible to buy an apple tree with six different branches and six different types of apples. The more common way to reproduce is sexual reproduction. In order for this to happen gametes must be produced and fertilized. Seeds‚ fruits‚ and embryos must also be developed. The two main advantages of reproducing this way are new genetic combinations and seeds spread over a large area. The following are the reproductive parts in this process

Coral reefs are a highly complex and diverse habitat‚ supporting a wide array of marine species. These particular structures also play an important role in the global economy through their involvement in different industries‚ especially fishing and tourism. However‚ over the past several decades‚ the influx of anthropogenic carbon dioxide (CO₂) as a result of mass fossil fuel combustion has resulted in the global degradation of these economically and ecologically crucial habitats. The key process
