Which of the following is not hydrophilic?
A.
Carbohydrates
B.
Lipids
C.
Proteins
D.
Nucleic acid
Correct Answer B. Lipids
Explanation Lipids are not hydrophilic because they are nonpolar molecules that do not readily dissolve in water. Unlike carbohydrates, proteins, and nucleic acids, lipids have a hydrophobic nature due to their long hydrocarbon chains. This hydrophobicity makes lipids insoluble in water and causes them to aggregate together, forming structures such as cell membranes.

5.
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 reticulum
Explanation 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.

A basement membrane occurs between:
A.
Muscle and nerve tissue
B.
Epithelial and connective tissue
C.
Connective tissue and muscle tissue
D.
Brain and nervous tissue
Correct Answer B. Epithelial and connective tissue
Explanation A basement membrane occurs between epithelial and connective tissue. This membrane is a thin, specialized extracellular matrix that provides structural support and acts as a barrier between these two types of tissues. It helps to anchor the epithelial cells to the underlying connective tissue and also regulates the exchange of molecules and nutrients between them. The basement membrane plays a crucial role in maintaining the integrity and function of epithelial tissues throughout the body.

9.
Epithelial tissue functions in:
A.
Secretion
B.
Absorption
C.
Protection
D.
All of the above
Correct Answer D. All of the above
Explanation Epithelial tissue is a type of tissue that lines the surfaces of organs, blood vessels, and cavities throughout the body. It serves multiple functions including secretion, absorption, and protection. Epithelial cells can produce and release substances such as enzymes, hormones, and mucus. They also have the ability to absorb nutrients and water from the surrounding environment. Additionally, epithelial tissue acts as a barrier, protecting underlying tissues from mechanical injury, pathogens, and harmful substances. Therefore, the correct answer is "all of the above" as epithelial tissue performs all these functions.

Connective tissue fibers are produced by:
A.
Macrophages
B.
Mast cells
C.
Fibroblasts
D.
All of the above
Correct Answer C. Fibroblasts
Explanation Fibroblasts are responsible for producing connective tissue fibers. Macrophages and mast cells are types of immune cells that play a role in the immune response and inflammation, but they do not directly produce connective tissue fibers. Therefore, the correct answer is fibroblasts.

Adipose tissue is a specialized form of:
A.
Fibrous connective tissue
B.
Elastic connective tissue
C.
Loose connective tissue
D.
Reticular connective tissue
Correct Answer C. Loose connective tissue
Explanation Adipose tissue is a specialized form of loose connective tissue because it is composed of adipocytes, which are cells that store fat. Loose connective tissue is characterized by a loose arrangement of cells and fibers, allowing for flexibility and support. Adipose tissue is found throughout the body and serves as a source of energy storage, insulation, and cushioning for organs. It is not fibrous connective tissue, elastic connective tissue, or reticular connective tissue, as those have different structural and functional properties.

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 cells
Explanation 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.
