PLEASE HELP John had a science fair project that he needed to do. He wanted to test the effects that organic and chemical fertil

izers had on plant growth. John predicted that the organic fertilizer would make the plants grow taller. He used three pots, three of the same type of seed, soil, organic fertilizer, chemical fertilizer, water, and a ruler. John put soil in the pots. He added chemical fertilizer to the first pot, organic fertilizer in the second pot, and no fertilizer in the third pot. He then planted one seed in each pot. John had to water the pots daily. He also checked for growth and took measurements for a period of 10 days. He measured the height of the plants. Height of Plant Days No Fertilizer (cm) Chemical Fertilizer (cm) Organic Fertilizer (cm) 1 0 0 0 2 0 0 0 3 0 0 0 4 0 0 0 5 0 0.5 0 6 0 1.3 0 7 0 1.9 0.3 8 0 2.2 1.6 9 0 4.5 3.2 10 0.2 5.2 3.8 As a real-world application, how can this experiment be beneficial?

Question 1
noname [10]
1 - A ground level plant develops curling tendrils that wrap around other objects so it can "climb".

This is a species changing over time as it was originally a ground level plant but began to climb higher.

2 - Over many generations.

This is because diversity takes time and has to be integrated through generations; for instance, marriage. In a family, it becomes more diverse after the next generation as each generation is likely to marry someone of another ethnicity and allow the family tree to become more diverse.

3 - Mutate or Survive

It depends on what it means by mutate - develop a mutation to make it adaptable? If that's the case, then mutations within the DNA would be a result of adaptation and increase survival. Otherwise, survive is the obvious answer as adaption allows for species to move around and live longer.

Hope this helps!
