If you flip a penny 99 times and each time it came up heads then the chance of the penny coming up heads is ___
Helga [31]
The chances of heads as a result when flipping a penny will always be 50%. Although heads came up 99 times in a row, the events that occurred before will not affect the probability of the current event in terms of a coin flip.

There are 1 out of 2 chances of it occurring or 1/2. Divide that and multiply it by 100% to get the probability in percent. So the answer will be 50%.

The answer is B.

She notices that the muscle cells are loaded with mitochondria while the macrophages have abundant lysosomes. why is this so?
Kaylis [27]

The muscle cells are loaded with mitochondria to allow large amounts of ATP production while the macrophages have abundant lysosomes to digest the debris and dead organisms like bacteria.

Mitochondria are known as the powerhouse of a cell. This is because most of the ATP production used by various systems in their operation is produced by mitochondria. A chemical called NADH is produced in the mitochondrial matrix through the Krebs cycle. The enzymes embedded in the mitochondrial membrane use this chemical to produce Adenosine Triphosphate, generally known as ATP.

Macrophages are phagocytic white blood cells involved in engulfing and killing pathogens. They are involved in the innate immune response of the body. Lysosomes have specialized enzymes that can kill these pathogens.

Muscle cells need to contract or expand for which they require energy. Thus, they have abundant mitochondria. Whereas, the macrophages have abundant lysosomes to help them kill disease-causing pathogens like a virus or bacteria.

To know more about ATP production in mitochondria, refer to the following link:
