I think there is a 50% chance of the coin landing on either side because the labelling of the coin will not affect the balance of the coin, and therefore won’t alter the flip. Labelling the coin ‘b’ and B’ will result in a coin flip no different from if the coin remained unlabelled.
The sun provides the energy for photosynthesis. Cells use sugar as a source of energy. The products of cellular respiration are CO2 and H2O. These products are used by plants to make sugar and oxygen through photosynthesis.
Evolution is the change in an animal over time. Evolution causes this one animal to branch out into many different species of animals.
How evolution starts- There is a mutation in the genes of one animal. If the mutation helps the animal, than the animal breeds and passes on this mutation. This is natural selection. Natural selection is the starting point of evolution because all of the helpful mutations get passed down to change the species over time for the animals' benefit.
I really hope this helps you
