Answers:
1.)
Solution: c) Arthropoda
Organisms of Arthropoda have jointed appendages of jointed foot and it is the largest group of organism. All the ticks, mites, crustaceans, millipedes and insects are included in the phylum Arthropoda.
2.)
Solution: d) Arthropoda
Arthropoda is the largest phylum of animal kingdom because it consist of over two third of all named species on this planet.
3.)
Solution: d) Blood
Body cavity of most of arthropods is a Hemocoel which is filled with blood. Where, hemo means blood and coel mean body cavity.
4.)
Solution: a) Open
Open type of circulatory system is present means all the tissue and cells are directly bathed into the blood stream.
5.)
Solution: c) Respiration by Parapodia
Respiration by Parapodia is incorrect because it takes place in the Annelids. Arthropods are allowed to respire by book lungs, via tracheal tubes, gills, and book lungs.
6.)
Solution: c) Malpighian tubules
In arthropods excretion occurs through malpighian tubules which work as a kidney to excrete uric acid as waste material from the body.
7.)
Solution: a) Spiders
An example Spider belongs to the subphylum Chelicerata. Crab belongs to Crustacea, Centipedes belong Myriapoda and Springtails belong Hexaposa.
8.)
Solution: b) They are all oviparous
This option is incorrect because few members of arthropods are viviparous also which directly gives birth to the young ones such as aphids.
9.)
Solution: c) 6
Total six pairs of appendages are present in the animals of Chelicerata. 1st pair helps in feeding, Have a pair of pedipalps. Remaining four pairs help in walking.
10.)
Solution: b) Chitinous
The body of arthropods is covered by a chitinous exoskeleton which is made up of an n-acetyl glucosamine unit.
11.)
Solution: d) Venom
All the spiders possess fangs that are connected to venom glands. It produces venom to dispatch its prey.
12.)
Solution: c) Head, thorax, abdomen
The body of arthropods is properly segmented into head, thorax and abdomen.
13.)
Solution: b) Webs
Spiders do have spin silk which they use and make webs. Spider webs help to trap prey.
14.)
Solution: b) Limulus
Limulus is called as the living fossil because it continues to remain unchanged from past 190 million years.
15.)
Solution: c) Spiracles holes
In the Arthropods, trachea is lined tube in spiracles and this is lined by chitin. Spiracle holes are the small openings that exchange gas.
16.)
Solution: b) Caterpillar
The female Bombyx mori or silkworm lays egg from which after sometime larvae hatch which are called as caterpillars.
17.)
Solution: d) Uniramia- very few species than other phyla
Uniramia is phyla that contains more species when compared to all other groups of organisms that are living.
18.)
Solution: d) Both (a) & (b)
Apis is the scientific name of honey bee which produces honey that can be sold in the market at high prices due to which it becomes economically important.
19.)
Solution: a) Class Pycnogonida
Sea spiders belong to class Pycnogonida. Horseshoe crabs represent class Merostomata, Ticks and Scorpions represent class Arachnida and Trilobites represent class Trilobita.
20.)
Solution: a) Apis, Bambyx, Culex
These three belong to the same phylum of Arthropoda.
21.)
Solution: d) Spiders
Spiders belong to the subphylum Chelicerata. All the remaining animals belongs to the subphylum Uniramia.
22.)
Solution: a) True
Balance organ or statocyst provides movement-related information to the brain which further helps in maintaining the balance or stability of the organism.
23.)
Solution: b) Double branch
In the appendages of Arthropods, two types of branches are there. First one is Uniramous and other one is Biramous. Where, Biramous show two branches.
24.)
Solution: b) Bilateral
Bilateral symmetry is present in arthropods which divides the body into identical left and right halves.
25.)
Solution: b) Egg- larva- pupa- adult.
Egg- larva- pupa- adult this is the complete metamorphosis. Egg- juvenile- adult is the incomplete metamorphosis.
26.)
Solution: c) Royal jelly
Royal jelly is secreted from mandibular and hypopharyngeal gland of nurse worker bees to provide nourishment to the young larvae and the adult queen bee.
27.)
Solution: d) Blue
The blood of spiders is blue in color. Blood of spider contains a copper-based protein.
28.)
Solution: a) Segmented, coelomate
Segmented means the body is divided into proper segments and coelomate because the body consist of a coelom lined by mesoderm.
29.)
Solution: d) Merostomata – Horseshoe crabs
Sea spider is included in the Pycnogonida. Ticks and whip scorpions are included in the Arachnida. Merostomata include Horshoe crabs.
30.)
Solution: b) Uricotelic
Cockroaches excrete uric acid as waste material as it requires less water for excretion so they are called as uricotelic.
