On a tour of African countries, Mark contracts a bad case of traveler's diarrhea. Because he can't eat very much, his body starts to use energy sources other than carbohydrates. This would result in

a. increased levels of urea in the blood.

b. ketosis and a decreased blood pH.

c. increased gluconeogenesis in the liver.

d. lipid metabolism.

e. All of the answers are correct.

Explanation:

Traveler's diarrhea is an intestinal infection that occurs as a result of eating or drinking contaminated food or water, food handlers who do not wash their hands after they use the bathroom can transmit the infection to people who consume the contaminated food

Due to diarrhea, kidney don't work properly and level of urea increases in blood

Due to the low carbohydrate intake, ketosis occurs in which stored fat is metabolized which results in build up of acids called ketones

If the body starts to use energy sources other than carbohydrates then it means it is using the stored energy, gluconeogenesis fulfills glucose requirement of cell by synthesis of glucose from non carbohydrate material

To supply with energy lipid metabolism occurs, fatty acids are oxidized and energy in the form of ATP is produced

compost can be added to topsoil as a:
