Answer: Natural Errors
Explanation: Mutagens can erase parts of DNA that then replicate, but is not a mistake made in copying DNA so that's not it. UV Radiation distorts DNA, but is not necessarily a mistake made in copying it. Natural Errors are mutations made by cells when they copy base pairs and ineffectively or for some other reason mutate/do not create the correct DNA, and the failure of cells to correct this is a mutation. This is also known as an error in DNA replication
The correct answer is A. Adequacy
Explanation:
In nutrition, the term "adequacy" refers to the necessary amount of nutrients or food a person needs to consume to be healthy which depends on the physical activity, requirements and medical conditions of the individual. In this way, Jamie's diet lacks adequacy because as an athlete she required 2.800 kilocalories; however, she is only consuming 1.600 kilocalories each day and this means she is not consuming the necessary amount of nutrients and food and therefore her diet is inadequate for her requirements and physical activity level.
The right answer is the large intestine.
The colon is part of the digestive system. Also called the large intestine, the colon follows the small intestine and forms the last part of the digestive system. It consists of several parts:
the caecum (from which leaves the vermiform appendage);
the ascending colon (right);
the transverse colon;
the descending colon (left);
the sigmoid colon;
and the rectum.
Its role is mainly to eliminate waste, absorb water, maintain the water balance and absorb certain vitamins. Chyle from the small intestine lacks almost all (90%) of the nutrients already absorbed by the digestive system. Chyle mixes in the colon with mucus and intestinal bacteria to form the feces. Bacteria capable of digesting the fibers form new molecules that the colon is then able to assimilate.
