  • 2. 

    Infected arthropods are more likely near water.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    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.

    Adult arthropods are non feeding and the larva of these arthropod can directly absorb food through the body wall.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    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.

    Hatching of Moniliformis eggs may cause the intermediate host: 

    • To move slower

    • Cause animals to swim on the surface

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    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.

    Arthropods are Facultative anaerobes.

    • True (VERY true DAMN IT!!!)

    • 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.

    Dioctophyme renale is a parasite of aquatic birds and terrestrial mammals

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Dioctophyme renale is a parasite that can infect both aquatic birds and terrestrial mammals. This means that it can be found in both water-dwelling birds and land-dwelling mammals, making the statement true.

    Drug that inhibits mitochondrial electron transports by binding with tubulin to interfere with mt related processes

    • Piperazine

    • Benzimidazole

    • Ivermectin

    Correct Answer
    A. Benzimidazole
    Explanation
    Benzimidazole is the correct answer because it is a drug that inhibits mitochondrial electron transport by binding with tubulin to interfere with mitochondrial-related processes. This means that benzimidazole disrupts the normal functioning of mitochondria, which are responsible for producing energy in cells. By interfering with mitochondrial electron transport, benzimidazole can have various effects on cellular processes and may be used as a targeted therapy for certain conditions.

    What are the characteristics of Nemataphores???

    • Horsehair worm (gordian worms)

    • Larvae parasites of terrestrial invertebrates

    • Pseudocoelomates

    • Dioecious

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    The given answer, "All of the above," is correct because nemataphores, specifically horsehair worms, exhibit all of the mentioned characteristics. Horsehair worms are larvae parasites of terrestrial invertebrates, they are pseudocoelomates (having a fluid-filled body cavity), and they are dioecious (having separate male and female individuals). Therefore, all of these characteristics apply to nemataphores.

    Causes Murine Typhus

    • Rickettsia mooseri

    • Borrelia recurrensis

    • Rochalimaea quintana

    Correct Answer
    A. Rickettsia mooseri
    Explanation
    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.

    The telmophage of Hemaphagus

    • Insect feeds on pool of blood that drains from blood vessels

    • Mouthparts in direct contact with blood

    • Lack peritrophic membrane

    Correct Answer
    A. Insect feeds on pool of blood that drains from blood vessels
    Explanation
    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.

    The Nervous system of the Phylum Nematoda is a(n):

    • Posterior nerve ring

    • Anterior nerve ring

    • Mid-intestinal ring

    Correct Answer
    A. Anterior nerve ring
    Explanation
    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.

    The lacunar system of arthropods are

    • Hydrostatic

    • Hypotonic

    • Hypertonic

    • Hydrophilic

    • Hydrolytic

    Correct Answer
    A. Hydrostatic
    Explanation
    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.

    Solenophages are

    • Mouthparts in direct contact with blood

    • Insect feeds on pool of blood that drains from blood vessels

    • Nucleotides (ADP, ATP) released by aggregating platelets

    Correct Answer
    A. Mouthparts in direct contact with blood
    Explanation
    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.

    The tegumental surface of Arthropods contain:

    • Surface coat/glycocalyx

    • Striped zone: crypts to increase surface area

    • Facultative anaerobes

    • A and C

    • A and B

    Correct Answer
    A. A and B
    Explanation
    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.

    Ivermectin inhibits:

    • Mitochondrial electron transport

    • Esophageal pumping

    • Scolices attachement

    Correct Answer
    A. Esophageal pumping
    Explanation
    Ivermectin inhibits esophageal pumping. This means that it prevents the movement of the esophagus, specifically the pumping action that helps in the movement of food from the mouth to the stomach. By inhibiting esophageal pumping, Ivermectin can interfere with the normal functioning of the digestive system and potentially disrupt the feeding and survival of certain organisms, such as parasites.

    Acanthocephala like Nemataphores contain pseudocoelomates but differs from Nemataphores by having _____ ________ with hooks and ___________ (i.e. a constant number of nuclei).

    Correct Answer
    eutely
    -proboscis retractable
    Explanation
    Acanthocephala, like Nemataphores, are pseudocoelomates. However, they differ from Nemataphores in two ways. First, Acanthocephala exhibit eutely, which means they have a constant number of nuclei in their cells. Second, Acanthocephala have a retractable proboscis that contains hooks.
