Biology

1. 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.

2. What is the main function of estuaries?

Correct answer: B

Rationale: Rationale: Estuaries are coastal areas where freshwater from rivers and streams mixes with saltwater from the ocean. They serve as important habitats for a variety of marine life, including fish, birds, and other wildlife. Estuaries provide shelter, breeding grounds, and food sources for many species, making them crucial for the overall health of marine ecosystems. While estuaries can help filter pollutants to some extent, their primary function is to support and sustain diverse populations of plants and animals. Storing carbon dioxide and generating wind power are not main functions of estuaries.

3. Which of the following is NOT a function of the nervous system?

Correct answer: C

Rationale: The correct answer is C: 'Producing insulin.' The nervous system is responsible for detecting touch (option A), regulating body temperature (option B), and controlling muscle movement (option D). Insulin production is actually regulated by the endocrine system, specifically the pancreas. Insulin helps regulate blood sugar levels, which is not a function of the nervous system. It is important to differentiate between the roles of the nervous system and the endocrine system in maintaining bodily functions.

4. Biodiversity is important for healthy ecosystems because it:

Correct answer: B

Rationale: Rationale: Biodiversity refers to the variety of living organisms in a particular area. A diverse ecosystem is better able to withstand and recover from disturbances such as natural disasters, climate change, or human impacts. This is because different species play unique roles in the ecosystem, and a higher level of biodiversity means there are more species available to fulfill these roles. For example, if one species is negatively affected by a disturbance, other species may be able to compensate for its loss, maintaining the overall functioning of the ecosystem. Therefore, biodiversity provides stability and resilience to disturbances, making ecosystems healthier and more sustainable.

5. The phrase "green alternative" suggests that bioremediation is...

Correct answer: C

Rationale: The passage contrasts bioremediation with "traditional methods," explicitly linking it to being environmentally friendly.

6. What is the purpose of genetic counseling?

Correct answer: C

Rationale: To provide information and support to individuals and families with genetic risks. Genetic counselors explain the implications of genetic testing, discuss risks and options, and offer emotional and psychological support.
