Concise Short Quiz on Biology 22 Second Exam Coverage
All questions are based on the student handbook by AV Hallare, PhD

Questions and Answers

1.

Syncitial Tegument is the invertebrate body covering found ___ .
- A.
  
  Trematodes
- B.
  
  Planarians
- C.
  
  Poriferans
- D.
  
  Annelids
- E.
  
  Coelenterates
Correct Answer
A. Trematodes

Explanation
Syncitial tegument is the invertebrate body covering found in trematodes. Trematodes, also known as flukes, are parasitic flatworms that infect a variety of hosts including humans. The syncitial tegument is a specialized outer layer of the fluke's body that allows for nutrient absorption and protection against the host's immune response. This unique tegument structure is an adaptation that enables the fluke to survive and thrive in its parasitic lifestyle.

2.

This is the special integument found in nematodes.
- A.
  
  Syncitial Tegument
- B.
  
  Non-Chitinized Cuticle
- C.
  
  Trichocysts
- D.
  
  Nematocysts
- E.
  
  Choanocytes
Correct Answer
B. Non-Chitinized Cuticle

Explanation
The correct answer is Non-Chitinized Cuticle. Nematodes have a unique integument called the cuticle, which is a tough, flexible, and protective outer covering. Unlike other organisms, the cuticle of nematodes does not contain chitin, a structural polysaccharide commonly found in the exoskeleton of arthropods and the cell walls of fungi. Instead, the cuticle of nematodes is composed of collagen and other proteins, making it non-chitinized. This non-chitinized cuticle provides support and protection to the nematode's body, allowing it to survive and thrive in various environments.

This is a layer of the amphibian integument that is also known as the Transitional Zone.
- A.
  
  Stratum Corneum
- B.
  
  Stratum Compactum
- C.
  
  Stratum Germinativum
- D.
  
  Statrum Malphigi
- E.
  
  Stratum Spongiosum
Correct Answer
D. Statrum MalpHigi

Explanation
The correct answer is Stratum Malphigi. The stratum Malphigi is a layer of the amphibian integument that is also known as the Transitional Zone.

This is a layer of the amphibian integument that contains chromatophores.
- A.
  
  Stratum Corneum
- B.
  
  Stratum Compactum
- C.
  
  Stratum Germinativum
- D.
  
  Stratum Malphigi
- E.
  
  Stratum Spongiosum
Correct Answer
E. Stratum Spongiosum

Explanation
The stratum spongiosum is a layer of the amphibian integument that contains chromatophores. Chromatophores are pigment-containing cells that allow amphibians to change their skin color for camouflage or communication purposes. The stratum spongiosum is responsible for housing these cells and facilitating their color-changing abilities.

This is the layer containing areolar connective tissue in human skin
- A.
  
  Stratum Lucidum
- B.
  
  Stratum Spinosum
- C.
  
  Stratum Germinativum
- D.
  
  Papillary Layer
- E.
  
  Reticular Layer
Correct Answer
D. Papillary Layer

Explanation
The papillary layer is the layer of the dermis that contains areolar connective tissue. It is located just below the epidermis and is responsible for providing nourishment to the epidermis. This layer contains blood vessels, lymphatic vessels, and sensory nerve endings. It also contains dermal papillae, which are small projections that increase the surface area for nutrient exchange between the dermis and epidermis. The papillary layer plays a crucial role in maintaining the health and integrity of the skin.
