Answer;

C) A positive feedback loop.

Explanation;

-Biological systems operate on a mechanism of inputs and outputs, each caused by and causing a certain event. A feedback loop is a biological occurrence in which the output of a system amplifies the system (positive feedback) or inhibits the system (negative feedback)

-Oxytocin is controlled by a positive feedback mechanism where release of the hormone causes an action which stimulates more of its own release. When contraction of the uterus starts, for example, oxytocin is released which stimulates more contractions and more oxytocin to be released.

Harman [31]

Answer:

A. anaerobic respiration in muscle cells, forming lactic acid

Explanation:

Running marathon is a vigorous exercise, which often leads to excessive use of oxygen in the cells of the athlete. This causes the cells to switch from the aerobic (with oxygen) to the anaerobic (without oxygen) mode of respiration. This anaerobic respiration produces a product called LACTATE OR LACTIC ACID.

The lactic acid becomes excessive and gets stored in the muscle cells of the athlete. This often leads to cramps, muscle pulls etc. during the marathon. Therefore, an individual running a marathon may experience periods of oxygen deprivation that can lead to anaerobic respiration in muscle cells, forming lactic acid.
