Answer:
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during cell division (mitosis/meiosis). There are three forms of nondisjunction: failure of a pair of homologous chromosomes to separate in meiosis I, failure of sister chromatids to separate during meiosis II, and failure of sister chromatids to separate during mitosis. Nondisjunction results in daughter cells with abnormal chromosome numbers (aneuploidy).
Explanation:
Describe the appearance of chromosome during the different stages of meiosis and mitosis?
Answer:
Chromosomes compress, thicken, shorten, and become more apparent during prophase. At the centromere, chromosomes appear as two sister chromatids fused together. Chromosomes line up on the equator during metaphase.

How does photosynthesis contribute to the organism’s energy needs
Answer:
Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as cellular respiration.
