The functions of ___ are protection, absorption, secretion, and excretion.
- A.
Nerve tissue
- B.
Connective tissue
- C.
Epithelial tissue
- D.
Muscle tissue
Correct Answer
C. Epithelial tissueExplanation
Epithelial tissue is responsible for protection as it forms a barrier between the internal and external environment of the body. It also plays a role in absorption, as certain types of epithelial cells have specialized structures such as microvilli to increase surface area for absorption of nutrients. Epithelial tissue is involved in secretion, as certain cells produce and release substances such as hormones, enzymes, and mucus. Lastly, epithelial tissue is involved in excretion, as certain cells in the kidneys and other organs help in the elimination of waste products from the body.Rate this question:

This structure is the site of protein synthesis.
- A.
Ribosome
- B.
Lysosome
- C.
Mitochondria
- D.
Golgi apparatus
Correct Answer
A. RibosomeExplanation
The ribosome is responsible for protein synthesis in cells. It is a small, spherical structure found in the cytoplasm and on the rough endoplasmic reticulum. Ribosomes read the genetic information from mRNA and use it to assemble amino acids into proteins. This process is essential for the growth and maintenance of cells, as proteins are involved in various cellular functions. Therefore, the ribosome is the correct answer as it is directly involved in protein synthesis.Rate this question:

Which organ system is responsible for elimination of wastes and maintaining homeostasis, including electrolyte, water, and acid/base balance?
- A.
Endocrine
- B.
Reproductive
- C.
Urinary
- D.
Nervous
Correct Answer
C. UrinaryExplanation
The urinary system is responsible for the elimination of wastes from the body and maintaining homeostasis by regulating electrolyte, water, and acid/base balance. The kidneys filter waste products from the blood and produce urine, which is then excreted from the body. The urinary system also helps regulate the body's fluid levels and pH balance. The other organ systems listed (endocrine, reproductive, and nervous) do not have primary functions related to waste elimination or maintaining homeostasis in the same way as the urinary system.Rate this question:

- A.
Respiratory
- B.
Lymphatic
- C.
Cardiovascular
- D.
Digestive
Correct Answer
B. LympHaticExplanation
The correct answer is lymphatic. The lymphatic system is responsible for transporting antibodies and cells that protect the body from foreign substances. It helps in the immune response by filtering and removing waste, toxins, and pathogens from the body. Additionally, it transports proteins and fluids throughout the body, maintaining fluid balance and aiding in the absorption of fats from the digestive system.Rate this question:

- A.
Respiratory
- B.
Lymphatic
- C.
Cardiovascular
- D.
Digestive
Correct Answer
C. CardiovascularExplanation
The cardiovascular system's main function is to transport oxygen, carbon dioxide, deliver nutrients and hormones, and remove waste products. It consists of the heart, blood vessels, and blood. The heart pumps oxygenated blood to the body's tissues and organs, while carrying waste products such as carbon dioxide away. The blood vessels, including arteries, veins, and capillaries, transport the blood throughout the body. This system plays a crucial role in maintaining homeostasis and ensuring the proper functioning of all other organ systems.Rate this question:

- A.
Respiratory
- B.
Lymphatic
- C.
Cardiovascular
- D.
Digestive
Correct Answer
A. RespiratoryExplanation
The respiratory system is responsible for providing the body with oxygen and removing carbon dioxide. It consists of organs such as the lungs, trachea, and bronchi, which are involved in the process of breathing. Oxygen is inhaled through the respiratory system and transported to individual tissue cells through the bloodstream, while carbon dioxide, a waste product of cellular respiration, is expelled from the body through exhalation.Rate this question:

- A.
Lymphatic
- B.
Endocrine
- C.
Nervous
- D.
Cardiovascular
Correct Answer
B. EndocrineExplanation
The endocrine system contains the glands that produce hormones, which are chemical messengers that provide communication and control over various parts of the body. These hormones are released into the bloodstream and travel to target cells or organs, where they regulate processes such as growth, metabolism, and reproduction. The endocrine system plays a crucial role in maintaining homeostasis and coordinating the body's response to internal and external stimuli.Rate this question:

Which system transmits impulses, responds to change, is responsible for communication, and exercises control over all parts of the body?
- A.
Reproductive
- B.
Integumentary
- C.
Endocrine
- D.
Nervous
Correct Answer
D. NervousExplanation
The nervous system is responsible for transmitting impulses, responding to change, and exercising control over all parts of the body. It is the main communication system in the body, allowing different parts of the body to communicate and coordinate their functions. The reproductive system is responsible for reproduction, the integumentary system is responsible for protecting the body, and the endocrine system is responsible for producing and regulating hormones. None of these systems have the same functions as the nervous system, making nervous the correct answer.Rate this question:

Correct Answer
B. FlagellumExplanation
The flagellum is a structure found in human sperm cells that provides motility. It is a long, whip-like structure that allows the sperm to move and swim towards the egg for fertilization. The flagellum contains microtubules and motor proteins that work together to generate the necessary force for movement. This structure is essential for the sperm to reach and penetrate the egg, enabling successful fertilization.Rate this question:
