What classes are inlcuded in Myriapoda?
- A.
Chilopoda
- B.
Cubipoda
- C.
Diplopoda
- D.
Terapoda
- E.
Chelicerates
Correct Answer(s)
A. Chilopoda
C. DiplopodaExplanation
Myriapoda is a subphylum of arthropods that includes classes such as Chilopoda and Diplopoda. Chilopoda, also known as centipedes, are elongated arthropods with many legs and a single pair of legs per body segment. Diplopoda, also known as millipedes, are arthropods with two pairs of legs per body segment. Therefore, both Chilopoda and Diplopoda are included in the subphylum Myriapoda.Rate this question:

What classes are included in the Cheliceriformes?
- A.
Spiders
- B.
Scorpions
- C.
Merostomata
- D.
Eurypterida
- E.
Chilopoda
- F.
Pycnogonida
- G.
Arachnida
- H.
Worms
Correct Answer(s)
C. Merostomata
D. Eurypterida
F. Pycnogonida
G. ArachnidaExplanation
The Cheliceriformes class includes Merostomata, Eurypterida, Pycnogonida, and Arachnida. These classes are all part of the larger group of arthropods, which includes animals with jointed legs and a segmented body. Merostomata includes horseshoe crabs, Eurypterida includes extinct sea scorpions, Pycnogonida includes sea spiders, and Arachnida includes spiders, scorpions, and other arachnids. Worms and Chilopoda are not included in the Cheliceriformes class.Rate this question:

Except from insects, all Arthropod groups are ____ and have a ____ origin. They colonised ____ many times.
Correct Answer(s)
ancient marine land
ancient marine terrestrial environments
old sea landExplanation
Arthropods are a diverse group of animals that includes insects, crustaceans, arachnids, and others. This question is stating that all Arthropod groups, except insects, have an ancient marine origin and colonized terrestrial environments multiple times. This means that these groups originated in the ancient oceans and later adapted to live on land, while insects have a different origin and did not go through the same colonization process.Rate this question:

In Myriapoda, Chilopoda are carnivorous millipedes and Diplopoda are herbivorous centipedes.
- A.
True
- B.
False
Correct Answer

Chilopoda are carnivorous centipedes, and Diplopoda are herbivorous/detritivorous millipedes.Rate this question:

The Arthropod cuticle. ____ epicuticles limit water loss.
Correct Answer
waxy
WaxyExplanation
The Arthropod cuticle is a protective layer that covers the body of arthropods. The epicuticles, which are the outermost layers of the cuticle, play a crucial role in preventing water loss. They are composed of a waxy substance that forms a waterproof barrier, reducing the evaporation of water from the arthropod's body. This helps the arthropod to retain moisture and prevent dehydration. Therefore, both "waxy" and "Waxy" are correct answers as they accurately describe the nature of the epicuticles in limiting water loss.Rate this question:

Chelicerates have ____ their gills to form ___ ____.
Correct Answer
internalised book lungsExplanation
Chelicerates have internalized their gills to form book lungs. This means that their gills, which were originally located externally, have been brought inside the body and transformed into book lungs. Book lungs are respiratory organs found in some arachnids, such as spiders and scorpions. They consist of stacked, leaf-like structures that allow for gas exchange between the arachnid's body and the surrounding environment. This adaptation is believed to have evolved as a way for chelicerates to efficiently obtain oxygen while reducing the risk of desiccation.Rate this question:
- 9.
Gene expression says these (gills to book lungs) are very modified ___.
Correct Answer
limbs
legsExplanation
The correct answer is "limbs, legs" because gene expression indicates that gills and book lungs have undergone significant modifications, suggesting that they are highly adapted structures related to limbs and legs.Rate this question:
- 10.
What novel system has insects, millipedes, and some spiders developed which is not derived from limbs?
- A.
Limbs
- B.
Tracheal
- C.
Hairs
- D.
Book lungs
- E.
Gills
Correct Answer
B. TrachealExplanation
Insects, millipedes, and some spiders have developed a novel system called tracheal respiration, which is not derived from limbs. Tracheal respiration involves a network of tubes called tracheae that deliver oxygen directly to the tissues of the organism. This system allows for efficient gas exchange without the need for specialized respiratory organs like gills or book lungs.Rate this question:

In many insect groups, _____ allows adults and larvae to occupy different niches.
Correct Answer
metamorphosis
MetamorphosisExplanation
Metamorphosis is the process by which insects undergo a series of distinct developmental stages, allowing them to occupy different ecological niches as adults and larvae. This transformation involves significant changes in body structure, physiology, and behavior. Through metamorphosis, insects can adapt to different environments, exploit different food sources, and avoid competition between adults and larvae for the same resources. This strategy enhances their survival and reproductive success by maximizing their utilization of available resources and reducing competition within their species.Rate this question:

Arthropod origins, their ancestor was probably a 'lobopod' similar to what subphyla?
- A.
Trilobitomorpha
- B.
Myriapoda
- C.
Crustacea
- D.
Onychophora
- E.
Cheliceriformes
Correct Answer
D. OnychophoraExplanation
The correct answer is Onychophora. Onychophora is a subphylum of invertebrates that includes velvet worms. They share several characteristics with arthropods, such as segmented bodies and jointed legs, which suggest a close evolutionary relationship. Lobopods, which are worm-like organisms with fleshy, unjointed legs, are considered to be the probable ancestors of arthropods. Onychophora is the closest living relative to lobopods and is therefore believed to be the closest living relative to the ancestor of arthropods.Rate this question:
