Noto 1 Nick Noto Dr. Strauch Fisheries and Wildlife 1100 14 February 2013 Homework #1 1. When cyanide is ingested and makes its way to the cellular level it messes up the  process of making ATP. The cyanide enters the cell and finds the mitochondria  and once it is in the mitochondria it inhibits production of ATP. Cyanide prevents  the Electron Transport Chain and oxidative phosphorylation from occurring.  When these processes are not allowed to occur, the electrons are not passed and  ATP is not produced, so the cell has no energy and it dies.  2. Through oogenesis one good new ovum is produced, while through  spermatogenesis four new cells are produces. When one ovum is produced, two to  three polar bodies are also produced to get rid of excess DNA and to help sustain  the life of the good ovum, which is bigger than the original cell because when it is  fertilized, it is what the new organism will grow in. The new sperm have their  DNA in the head and their mitochondria are stored in the middle section. When  the spermatid penetrates the ovum, only the head enters and its mitochondrial  DNA is left behind. Therefore, only the mother’s mitochondrial DNA is  transferred to the offspring and it can be observed to solve the problem with the  cattle.  3. When the dinosaurs went extinct, it opened up new resources and environments to  other mammals that previously competed with the dinosaurs. Durin
