Nicole was as diagnosed with Leigh Syndrome (LS). Leigh syndrome is said to be “a severe neurological disorder that is characterized by the degeneration of the central nervous system and is associated with a nuclear mutation in the SURF1 gene”. Which leads to a defect in a protein found in the mitochondria. It affects a protein normally found in cellular organelles, most likely the Mitochondria organelle which is involved in energy production. The aforesaid syndrome is passed down through autosomal recessive conditions. In the case of Kenneth and Vicki (Nicole’s parents), both of them may have working and nonworking copies of the gene and unfortunately, both of them passed down the nonworking gene to Nicole.
The option D is correct :The gametophytes of seed plants are never exposed to the external environment. Unlike spores, The gametophyte in seed plants is often tiny and is kept in the tissues of the sporophyte. The integument refers to the layers of sporophyte tissue that encircle the megasporangium.
seeds carry food reserves that can be used to support a young plant. While spores are distributed by the wind, seeds can be spread by animals. While spores only live a few days, seeds can slumber for weeks or even years. Seeds contain a supply of food in storage, in contrast to spores. If the conditions are right, seeds that have been transported far from the parent sporophyte may germinate and rely on stored nourishment to develop into seedlings. Spores and seeds vary primarily in that seeds have stored nourishment in their endosperm, which allows them to germinate in adverse conditions whereas spores do not, making them more dependent on good conditions for germination.
