In eukaryotes, beta oxidation of fatty acids takes place where? A) Rough ER B) Plasma membrane C) Mitochondria D) Plasma membrane

Beta oxidation of fatty acids take place in the c) Mitochondria and it is the process by which fatty acids are broken down in the body.

The half-life of Beryllium-11 is 13.81 seconds. How many seconds will it take for 1 gram of this isotope to decay to 0.0625 grams? (a) 41.43 seconds (b) 55.24 seconds (c) 21.5 seconds (d) 52 seconds

The answer is B) 55.24 seconds. Half-life is the time required for exactly half of the substance to decay. It takes 4 half lives to get from 1 gram to 0.0625. Meaning, it goes 1 g --> 0.5 g --> 0.25 g --> 0.125 g --> 0.0625, each time you divide by 2 to get its half and you need to do that 4 times. If Beryllium-11's half life is 13.81 seconds, and there is 4 half-lives, meaning 4 X 13.81 sec.

Which of the following subcellular structure in an eukaryotic cell is inherited from the mother? 1) Golgi bodies 2) Mitochondria 3) Nucleus 4) Cilia

Mitochondria contains genetic material and multiple enzymes important for biochemical processes of cell metabolism and energy production. It has a double membrane, the inner layer being folded inward to form layers (cristae). It is the only The genetic material is passed down from mothers to both sons and daughters, but sons cannot pass along their mothers' mitochondria DNA to their children. This is because mitochondrial DNA is transmitted through the female egg.
