Infected arthropods are more likely near water.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Arthropods are a group of invertebrate animals that include insects, spiders, and crustaceans. Many arthropods, such as mosquitoes and ticks, are known to transmit diseases to humans. These infected arthropods often require water sources for their breeding and survival. Mosquitoes, for example, lay their eggs in water, and ticks are commonly found in grassy or wooded areas near water sources. Therefore, it is true that infected arthropods are more likely to be found near water.Rate this question:

Adult arthropods are non feeding and the larva of these arthropod can directly absorb food through the body wall.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Adult arthropods are indeed non-feeding, meaning they do not actively consume food. Instead, the larva of these arthropods have the ability to directly absorb nutrients through their body wall. This is an adaptation that allows them to obtain the necessary nutrients for growth and development without the need for feeding.Rate this question:

- A.
Surface coat/glycocalyx
- B.
Striped zone: crypts to increase surface area
- C.
Facultative anaerobes
- D.
A and C
- E.
A and B
Correct Answer
E. A and BExplanation
The correct answer is A and B because the tegumental surface of Arthropods contains a surface coat/glycocalyx, which helps in protection and attachment, and a striped zone with crypts to increase the surface area, which aids in absorption and secretion.Rate this question:

The lacunar system of arthropods are
- A.
Hydrostatic
- B.
Hypotonic
- C.
Hypertonic
- D.
Hydrophilic
- E.
Hydrolytic
Correct Answer
A. HydrostaticExplanation
The lacunar system of arthropods is hydrostatic because it functions by using fluid pressure to support the body and aid in movement. This system consists of interconnected spaces filled with fluid, which creates a hydrostatic skeleton. This fluid-filled system allows arthropods to exert force against their muscles, enabling them to move and maintain their body shape.Rate this question:

Arthropods are Facultative anaerobes.
- A.
True (VERY true DAMN IT!!!)
- B.
False
Correct Answer
A. True (VERY true DAMN IT!!!)Explanation
Arthropods are organisms that have the ability to survive in both aerobic (with oxygen) and anaerobic (without oxygen) conditions. They can switch between these two metabolic pathways depending on the availability of oxygen. This flexibility allows them to adapt to various environments and survive in low-oxygen conditions. Therefore, it is true that arthropods are facultative anaerobes.Rate this question:

Hatching of Moniliformis eggs may cause the intermediate host:
- A.
To move slower
- B.
Cause animals to swim on the surface
- C.
All of the above
Correct Answer
C. All of the aboveExplanation
The hatching of Moniliformis eggs can cause the intermediate host to move slower and can also cause animals to swim on the surface. This means that both of these effects can occur as a result of the hatching of Moniliformis eggs.Rate this question:

Solenophages are
- A.
Mouthparts in direct contact with blood
- B.
Insect feeds on pool of blood that drains from blood vessels
- C.
Nucleotides (ADP, ATP) released by aggregating platelets
Correct Answer
A. Mouthparts in direct contact with bloodExplanation
Solenophages are mouthparts in direct contact with blood. This means that solenophages are structures or organs found in certain insects that come into direct contact with blood. This contact allows the insect to feed on a pool of blood that drains from blood vessels. Additionally, solenophages can also release nucleotides such as ADP and ATP, which are released by aggregating platelets.Rate this question:

The telmophage of Hemaphagus
- A.
Insect feeds on pool of blood that drains from blood vessels
- B.
Mouthparts in direct contact with blood
- C.
Lack peritrophic membrane
Correct Answer
A. Insect feeds on pool of blood that drains from blood vesselsExplanation
The correct answer is that the insect feeds on the pool of blood that drains from blood vessels. This is supported by the information provided in the question, which states that the insect's mouthparts are in direct contact with blood and that it lacks a peritrophic membrane. These characteristics suggest that the insect is adapted to feed on blood that is already outside of the blood vessels, such as blood that has pooled or leaked out.Rate this question:

Borrelia recurrensis's life cycle is as followed:spirochaete in bloodïƒ louse (in hemocoele) ïƒ person infected by crushing louse and scratching into skin
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The given statement is true. Borrelia recurrensis, a spirochaete, has a life cycle that involves being present in the blood, then being transmitted to a person through a louse. The louse carries the spirochaete in its hemocoele, and when the louse is crushed and the person scratches their skin, the spirochaete can enter the person's body. This cycle allows for the transmission of Borrelia recurrensis from lice to humans.Rate this question:

Causes Murine Typhus
- A.
Rickettsia mooseri
- B.
Borrelia recurrensis
- C.
Rochalimaea quintana
Correct Answer
A. Rickettsia mooseriExplanation
Rickettsia mooseri is the correct answer because it is the causative agent of Murine Typhus. Murine Typhus is a bacterial infection that is transmitted to humans through fleas that infest rats. Rickettsia mooseri infects the fleas, and when the fleas bite humans, the bacteria are transmitted. This infection can cause symptoms such as fever, headache, rash, and muscle aches. Therefore, Rickettsia mooseri is the correct answer as it is the specific bacterium that causes Murine Typhus.Rate this question:

The Nervous system of the Phylum Nematoda is a(n):
- A.
Posterior nerve ring
- B.
Anterior nerve ring
- C.
Mid-intestinal ring
Correct Answer
B. Anterior nerve ringExplanation
The correct answer is the anterior nerve ring. The nervous system of the Phylum Nematoda is characterized by a ring of nerves located in the anterior part of the body. This nerve ring serves as the main control center for coordinating sensory and motor functions in the nematode. It receives signals from sensory receptors located throughout the body and sends out motor signals to control muscle movement. This arrangement allows for efficient communication and coordination within the nervous system of the Phylum Nematoda.Rate this question:
