1.
Myriapods have a tail.
Correct Answer
B. False
Explanation
Myriapods do not have a tail. They are a group of arthropods that include centipedes and millipedes. While they may have long segmented bodies, they do not possess a distinct tail like some other animals. Therefore, the correct answer is False.
2.
Myriapods have both sperm sack and ovaries.
Correct Answer
A. True
Explanation
Myriapods, such as centipedes and millipedes, have both sperm sacks and ovaries. This means that they have both male and female reproductive organs, allowing them to produce both sperm and eggs. This is a characteristic feature of myriapods, distinguishing them from other groups of arthropods.
3.
There are five groups of Myriapods.
Correct Answer
B. False
Explanation
The statement is false because there are four groups of Myriapods, not five. Myriapods are a group of arthropods that include centipedes, millipedes, and other similar organisms. The four groups of myriapods are Chilopoda (centipedes), Diplopoda (millipedes), Pauropoda, and Symphyla.
4.
Myriapods have up to 400 pairs of legs.
Correct Answer
A. True
Explanation
Myriapods are a type of arthropod that includes millipedes and centipedes. They are known for their numerous legs, with some species having up to 400 pairs of legs. This makes the statement "Myriapods have up to 400 pairs of legs" true.
5.
Myriapods have been on the earth for up to 400 million years.
Correct Answer
A. True
Explanation
Myriapods have been on the earth for up to 400 million years. This statement is true because myriapods, which include centipedes and millipedes, are among the oldest groups of land-dwelling arthropods. Fossil evidence suggests that they have existed for hundreds of millions of years, making them one of the earliest terrestrial organisms.
6.
Myriapods mean many footed in:
Correct Answer
B. Latin
Explanation
The correct answer is Latin because "myriapods" is derived from the Latin words "myria" meaning many and "podos" meaning footed. Therefore, "myriapods" literally translates to "many footed" in Latin.
7.
Myriapods can live in sea water.
Correct Answer
B. False
Explanation
Myriapods are a group of arthropods that include millipedes and centipedes. They are primarily terrestrial organisms and are not adapted to live in sea water. They lack the necessary physiological adaptations to survive in a marine environment, such as the ability to regulate salt concentrations in their bodies. Therefore, the statement that myriapods can live in sea water is false.
8.
Most are Herbivores.
Correct Answer
A. True
Explanation
Most animals are herbivores, meaning they primarily consume plants as their source of food. This statement is generally true as many species, such as cows, deer, and rabbits, have adapted to a diet consisting mainly of plants. However, it is important to note that there are also many animals that are omnivores or carnivores, meaning they consume both plants and animals. Nonetheless, the statement holds true in terms of the overall distribution of herbivorous animals in the animal kingdom.
9.
Myriapods grow by shedding their skin.
Correct Answer
A. True
Explanation
Myriapods, which include creatures like centipedes and millipedes, do indeed grow by shedding their skin. This process is known as molting, and it allows them to shed their old exoskeleton and grow a new one. During molting, the myriapod secretes a new, soft exoskeleton underneath the old one. Once the new exoskeleton has hardened, the myriapod breaks out of the old one, leaving it behind. This allows the myriapod to continue growing and accommodate its increasing size.
