Crossing over and independent assortment allow individuals to be born which are not alike to another and their parents. As a result, genetic diversity is produced.
Part B:
The process 1 is meiosis. The process 3 is development by mitosis.
The reproductive organs form sperm and egg by the process of meiosis. During this process, the number of chromosomes is reduced so that the number of chromosomes of an individual can be maintained.
The zygote converts into an embryo in a process called germinal development. The zygote replicates by mitosis to form into an embryo.
Electric field , and if that’s wrong it should be electric force . Those are the only two that make sense
The intensity of light had greater impact on the rate of photosynthesis. It was observed that the jar in which the intensity of light was high, large amount of oxygen was produced as compared to the jar in which the intensity of light was low.
In the process of photosynthesis, oxygen is produced from the carbon dioxide. As the oxygen in the jar increases, the leaf disk rises with in the jar which also signifies the higher oxygen production with higher rate of photosynthesis in presence of high intensity of light.
