Biology

1. What is the main function of dietary fiber in the digestive system?

Correct answer: C

Rationale: Rationale: Dietary fiber refers to the indigestible portion of plant foods that passes relatively intact through the digestive system. While fiber does not provide energy directly to the body, it plays a crucial role in promoting the growth of beneficial gut bacteria. These bacteria help in the fermentation of fiber, producing short-chain fatty acids that can be used as an energy source by the body. Additionally, fiber helps regulate bowel movements, maintain gut health, and support overall digestive function. Therefore, the main function of dietary fiber in the digestive system is to promote gut bacteria growth.

2. What is the main verb tense in the following sentence? "She had already left before I arrived."

Correct answer: D

Rationale: The verb "had left" is in the past perfect tense, indicating an action completed before another past action ("arrived").

3. Which statement accurately describes the Linnaean system of classification?

Correct answer: D

Rationale: Rationale: The Linnaean system of classification, developed by Carl Linnaeus, is based on a hierarchical ranking system where organisms are grouped into categories based on shared characteristics. This system organizes organisms into a hierarchy of increasingly specific categories, from broad to narrow, such as kingdom, phylum, class, order, family, genus, and species. This hierarchical approach allows for the systematic organization and classification of a wide variety of organisms based on their similarities and differences.

4. Which of the following is the main organ responsible for producing bile?

Correct answer: A

Rationale: Rationale: The liver is the main organ responsible for producing bile. Bile is a greenish-yellow fluid that is produced by the liver and stored in the gallbladder. It plays a crucial role in the digestion and absorption of fats in the small intestine. The gallbladder releases bile into the small intestine when needed to aid in the digestion of fats. The pancreas is responsible for producing digestive enzymes and insulin, not bile. The stomach is primarily involved in the digestion of food through the secretion of gastric juices.

5. What is the difference between a homozygous recessive genotype and a homozygous dominant genotype?

Correct answer: D

Rationale: Rationale: - Homozygous recessive genotype refers to an individual having two identical recessive alleles for a particular gene (e.g., rr for a trait where r represents the recessive allele). - Homozygous dominant genotype refers to an individual having two identical dominant alleles for a particular gene (e.g., RR for a trait where R represents the dominant allele). - The difference between the two genotypes lies in the specific alleles present in each case, with homozygous recessive having two recessive alleles and homozygous dominant having two dominant alleles. - This genetic difference results in different phenotypes being expressed, as the dominant allele typically masks the expression of the recessive allele in heterozygous individuals.

6. What is the measure of the total amount of space occupied by an object?

Correct answer: d

Rationale: Volume is the measure of the total amount of space occupied by an object and is typically measured in cubic units such as cubic meters or liters.
