Choices: - bacteria poisoning - nutrition poisoning - meat poisoning - food poisoning A:

Ques: Q: Where does carbohydrate digestion begin in the body? Read this paragraph and choose the correct option from the provided answers: Digestion of Carbohydrates Carbohydrate digestion begins in the mouth (Figure 20.5 "The Principal Events and Sites of Carbohydrate Digestion"), where salivary -amylase attacks the -glycosidic linkages in starch, the main carbohydrate ingested by humans. Cleavage of the glycosidic linkages produces a mixture of dextrins, maltose, and glucose. (For more information about carbohydrates, see Chapter 16 "Carbohydrates". ) The -amylase mixed into the food remains active as the food passes through the esophagus, but it is rapidly inactivated in the acidic environment of the stomach. Figure 20.5 The Principal Events and Sites of Carbohydrate Digestion. Choices: - stomach - intestines - throat - mouth A:
Ans: mouth

Ques: Q: What has two chains of nucleotides, one more than rna? Read this paragraph and choose the correct option from the provided answers: RNA consists of just one chain of nucleotides. DNA consists of two chains. Nitrogen bases on the two chains of DNA form hydrogen bonds with each other. Hydrogen bonds are relatively weak bonds that form between a positively charged hydrogen atom in one molecule and a negatively charged atom in another molecule. Hydrogen bonds form only between adenine and thymine, and between guanine and cytosine. These bonds hold the two chains together and give DNA is characteristic double helix, or spiral, shape. Choices: - gna - fna - mna - dna A:
Ans: dna

Ques: Q: What is the plane that divides the body or an organ vertically into right and left sides? Read this paragraph and choose the correct option from the provided answers: The sagittal plane is the plane that divides the body or an organ vertically into right and left sides. If this vertical plane runs directly down the middle of the body, it is called the midsagittal or median plane. If it divides the body into unequal right and left sides, it is called a parasagittal plane or less commonly a longitudinal section. The frontal plane is the plane that divides the body or an organ into an anterior (front) portion and a posterior (rear) portion. The frontal plane is often referred to as a coronal plane. ("Corona" is Latin for "crown. ") The transverse plane is the plane that divides the body or organ horizontally into upper and lower portions. Transverse planes produce images referred to as cross sections. Choices: - median plane - parasagittal plane - anatomical plane - sagittal plane A:
Ans:
sagittal plane
