Answer:

Part A: The process of sexual reproduction is important because by this process organisms with varied genetic characteristics can be formed. 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.

Why is it difficult to observe individual chromosomes with a light microscope during interphase?
asambeis [7]

Answer:

They have uncoiled to form long, thin strands.

Explanation:

Chromosomes are present in cell nucleus and consist of chromatin. Genes are present in linear order on chromosomes.  The chromosomes become visible under the microscope as distinct structures during cell division. When cells are not dividing, the chromosomes decondense to loose their individuality and make the mass of chromatin.  

Chromatin is complex of DNA and packing proteins. As the cells enter the prophase stage of cell division, condensation of chromatin occurs and individual chromosomes become visible under microscope. Before that (during interphase), chromosomes are not visible as they are present in decondensed form.
