Test:

1. Which of the following is the largest gland in the human body?
a) Liver
b) Pancreas
c) Spleen
d) Gallbladder

2. What is the process by which plants convert sunlight into chemical energy?
a) Photosynthesis
b) Respiration
c) Transpiration
d) Fermentation

3. Which of the following is the primary function of the nephrons in the human kidney?
a) Blood filtration
b) Red blood cell production
c) Hormone secretion
d) Digestion

4. The process of breaking down complex food molecules into simpler substances is known as:
a) Absorption
b) Digestion
c) Assimilation
d) Excretion

5. Which of the following is a vestigial organ in humans?
a) Appendix
b) Pancreas
c) Stomach
d) Kidney

Solutions:

1. a) Liver - The liver is the largest gland in the human body, responsible for various functions such as detoxification, metabolism, and bile production.

2. a) Photosynthesis - The process by which plants convert sunlight into chemical energy is called photosynthesis. This process occurs in chloroplasts and involves the synthesis of glucose and oxygen.

3. a) Blood filtration - The primary function of nephrons in the human kidney is to filter waste products from the blood, reabsorb necessary substances, and maintain water and electrolyte balance.

4. b) Digestion - Digestion is the process by which complex food molecules are broken down into simpler substances that can be absorbed and utilized by the body.

5. a) Appendix - The appendix is considered a vestigial organ in humans as it no longer serves a significant purpose in digestion. It is believed to have played a role in the digestion of cellulose in our evolutionary ancestors.

By attempting and reviewing these questions, you can improve your understanding of important biological concepts and identify areas that require further study. Good luck with your exam preparation!
