  • 2. 

    Aquatic annelids use parapodia to move through water.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Aquatic annelids, such as leeches and marine worms, use parapodia to move through water. Parapodia are fleshy appendages that extend from the sides of the annelid's body. These structures are equipped with bristles, called setae, which help the annelids to anchor themselves and propel forward in the water. The parapodia also provide a larger surface area for increased locomotion and better control of movement. Therefore, the statement "Aquatic annelids use parapodia to move through water" is true.

    Annelids have an open circulatory system.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Annelids actually have a closed circulatory system. In a closed circulatory system, the blood flows through a network of vessels and is contained within the vessels at all times. This allows for more efficient transport of oxygen and nutrients throughout the body. Annelids, such as earthworms, have a series of vessels that carry blood and a pumping organ called the aortic arches to help circulate the blood. Therefore, the statement that Annelids have an open circulatory system is false.

    Food travels like this : esophagus (pharynx) -> crop -> gizzard -> intestine -> coelom

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The given statement is true. The explanation is that food travels through the esophagus, which is connected to the pharynx. From there, it moves to the crop, which is a storage organ in some animals. Next, it enters the gizzard, which helps in grinding and breaking down the food. After that, it moves into the intestine, where further digestion and absorption take place. Finally, the digested food enters the coelom, which is the body cavity where nutrients are distributed to the rest of the body.

    Examples of annelids are: (check all that apply)

    • Leeches

    • Earthworms

    • Birds

    • Sandworms

    • Ants

    Correct Answer(s)
    A. Leeches
    A. Earthworms
    A. Sandworms
    Explanation
    Annelids are a phylum of segmented worms. Leeches, earthworms, and sandworms are all examples of annelids. Leeches are blood-sucking parasites that belong to the class Hirudinea. Earthworms are commonly found in soil and belong to the class Oligochaeta. Sandworms are marine worms that live in sandy sediments and belong to the class Polychaeta. Birds, ants, and other insects are not annelids and do not belong to this phylum.

    Circular muscles stretch an annelid's body to make it ____________________.

    • Shorter and fatter

    • Longer and thinner

    • Longer and fatter

    • Shorter and thinner

    Correct Answer
    A. Longer and thinner
    Explanation
    Circular muscles in annelids contract, causing the body to elongate and become thinner. This is because when the circular muscles contract, they constrict the body in a circular motion, resulting in the stretching and elongation of the body. As a result, the annelid becomes longer and thinner in shape.

    Annelids can live in _____________. (check all that apply)

    • Saltwater

    • The sky

    • Fresh Water

    • Soil

    Correct Answer(s)
    A. Saltwater
    A. Fresh Water
    A. Soil
    Explanation
    Annelids, which include earthworms and leeches, are known to be able to live in saltwater, fresh water, and soil. They are adaptable creatures that can thrive in various environments, including aquatic habitats like saltwater and fresh water, as well as terrestrial habitats like soil. This adaptability allows them to occupy a wide range of ecosystems and play important roles in nutrient recycling and soil health.

     Annelids _________________.(check all that apply)

    • Undergo sexual reproduction

    • Undergo self-fertilization

    • Like to dance

    • Like to fly

    Correct Answer(s)
    A. Undergo sexual reproduction
    A. Undergo self-fertilization
    Explanation
    Annelids are a phylum of worms that includes earthworms and leeches. They are known to undergo sexual reproduction, where two individuals exchange genetic material to produce offspring. Additionally, some species of annelids also have the ability to undergo self-fertilization, where an individual can fertilize its own eggs. This allows them to reproduce even in the absence of a mate. Therefore, the correct answers for this question are "undergo sexual reproduction" and "undergo self-fertilization".

    Annelids can breathe like this (check all that apply)

    • Through noses

    • Through their skin

    • Through gills

    • Through their brains

    Correct Answer(s)
    A. Through their skin
    A. Through gills
    Explanation
    Annelids can breathe through their skin because their skin is thin and moist, allowing oxygen to diffuse into their bodies. They can also breathe through gills, which are specialized structures that extract oxygen from water. However, they cannot breathe through their noses or brains as these organs are not involved in the respiratory process.

    Longitudinal muscles stretch an annelid's body to make it ____________________.

    • Shorter and fatter

    • Longer and thinner

    • Longer and fatter

    • Fatter and thinner

    Correct Answer
    A. Shorter and fatter
    Explanation
    Longitudinal muscles in annelids contract and shorten the body, causing it to become shorter. At the same time, these muscles also thicken and increase in diameter, making the body fatter. Therefore, the correct answer is "Shorter and fatter."
