Lipids are synthesized in:
- A.
The Golgi apparatus
- B.
The smooth endoplasmic reticulum
- C.
The rough endoplasmic reticulum
- D.
The liver
Correct Answer
B. The smooth endoplasmic reticulumExplanation
Lipids are synthesized in the smooth endoplasmic reticulum. This organelle is responsible for the synthesis of lipids, including phospholipids and cholesterol. The smooth endoplasmic reticulum lacks ribosomes, which are present in the rough endoplasmic reticulum. The Golgi apparatus is involved in modifying and packaging lipids, but not in their synthesis. While the liver plays a role in lipid metabolism, the actual synthesis of lipids occurs in the smooth endoplasmic reticulum.Rate this question:

Shafts of hair are composed of:
- A.
Living dermal cells
- B.
Dead dermal cells
- C.
Living epidermal cells
- D.
Dead epidermal cells
Correct Answer
D. Dead epidermal cellsExplanation
Hair shafts are composed of dead epidermal cells. The hair shaft is the visible part of the hair that extends above the surface of the skin. It is formed by the hair follicle, which is located in the dermis layer of the skin. As the hair grows, the cells in the hair follicle push upwards and harden, eventually becoming keratinized and forming the hair shaft. These cells lose their nucleus and other organelles, making them dead cells. Therefore, the correct answer is dead epidermal cells.Rate this question:

Tissues, cells, organs, organelles, systems
- C.
Organs, organelles, systems, cells, tissues
- D.
Organelles, cells, tissues, organs, systems
Correct Answer
D. Organelles, cells, tissues, organs, systemsExplanation
The sequence " Organelles, cells, tissues, organs, systems" reflects the increasing complexity in the field of anatomy and physiology. Organelles, like the nucleus and mitochondria, operate within cells. Cells are the basic building blocks of life, which then combine to form tissues. These cells and their organelles come together to create organs, and multiple organs work in unison to form systems. This hierarchy demonstrates the progressive organization and complexity in understanding the human body's structure and function within the field of anatomy and physiology.Rate this question:

How is oxygen used by living organisms?
- A.
It controls the amount of heat produced.
- B.
Its a source of energy.
- C.
It is used to release energy that is stored in food.
- D.
It is part of water and is necessary to keep organisms hydrated.
Correct Answer
C. It is used to release energy that is stored in food.Explanation
Oxygen is used by living organisms to release energy that is stored in food through a process called cellular respiration. During cellular respiration, oxygen combines with glucose (a sugar molecule) to produce carbon dioxide, water, and ATP (adenosine triphosphate), which is the energy currency of cells. This process occurs in the mitochondria of cells and is essential for the survival and functioning of living organisms.Rate this question:
