... ingest the parasite larval stages and carry them around as a form of arrested development accumulating them until they have a chance of infecting a host. Pollination does not guarantee the transfer of the right type of pollen (compatible pollen of the same species as the stigma). Why flatworms are called acoelomates? The tear-free force (•) and crab release force ( ) of Octopus vulgaris plotted against its body weight. Ctenophores have a diffuse subepidermal net of non-polar neurons; beneath the comb rows, these neurons form an elongate mesh resembling nerve fibers. A large concentration of nerve tissue is also found around the mouth. Diverse invertebrate species have been used for studies of learning and comparative cognition. Body having meshwork of cells, internal cavities (AIPMT 2015) lined with food filtering flagellated cells and indi-rect development are the characteristics of phylum (a) Mollusca … Often, pollen of the wrong type, either from other species or from the same plant (if it is self-incompatible), also land on the stigma. Any true … Cephalopods have good visual discrimination learning abilities (Sanders 1975) and visual control is important in the predatory behaviour of cuttlefish (Messenger 1968). 30. The several physiopharmacological studies on the venoms of urolophus, trachinus, pterois, scorpaena, and synanceja suggest that these toxins produce certain identical reaction patterns, which differ for the most part only in their degree of reactivity. The break-free force of two octopuses (0.150 and 0.395 kg), calculated from earlier observations on isolated suckers, is shown as ( ). Members of Type I and II have similar locations of the six half-Cys (which form three disulfide bonds), as well as several other residues thought to play a role in biological activity or maintenance of the tertiary structure . Nv1-Nv6 PLA(2)s have identity with secreted human group (G)IB and GIIA PLA(2)s and PLA(2)s of the sea anemones Adamsia carciniopados and Urticina crassicornis. The neuroglial cell which constitute the rest of the neural system protect and support neurons. Projection neurons thus express higher calcium-dependent K+ currents. Projection neurons thus express higher calcium-dependent K+ currents. MCQs on Neurons Nerve Impulse. Next-generation transcriptome sequencing allows robust characterization of venom diversity and exploration of functionally unique tissues. Choose the term that does not belong in the following group and explain why it does not belong? Our experiment showed that once cuttlefish have experienced inedible prey, they can recognize and avoid it for a long time, emphasizing the flexibility of their feeding preference. What type of symmetry does this animal exhibit?-Bilateral Symmetry c. Is this animal Cephalized? Here is the compilation of all previous year question of General Awareness -Biology – with answers. Download : Download full-size image; Fig. Worms have specialised chemoreceptors (taste receptors) which react to chemical stimuli. These sense organs are located on the anterior part of the worm. The use of venom in intraspecific aggression is uncommon and venom-transmitting structures specifically used for intraspecific competition are found in few lineages of venomous taxa. What type of symmetry does this animal exhibit?-Bilateral Symmetry c. Is this animal Cephalized? a. Wilson. - radial symmetry (chordates are bilaterally symmetrical.) Data deposition: The raw data generated in this project have been deposited at the Sequence Reach Archive on GenBank under accessions SRS886541 (Anemonia sulcata), SRS891948 (Heteractis crispa), and SRS901540 (Megalactis griffithsi).Assembled transcriptomes, candidate toxin gene BLAST search results, candidate toxin genes sequence alignments, GO outputs, and differential gene expression … 1.The term biodiversity was first introduced by Walter Rosen (1985), and defined by E.D. Kerala Plus One Zoology Model Question Paper 5. Type III have … Relative expression levels for each of the tissue-specific transcriptomes were calculated using the program RSEM (Li and Dewey 2011) within the Trinity programming suite (Grabherr et al. 5. An icon used to represent a menu that can be toggled by interacting with this icon. Answer. The Cnidaria phylum includes organisms that are among the most venomous animals. 3.Aristotle is called the father of taxonomy (classical) and Carolus Linnaeus is the father of modern taxonomy. 4.Aristotle (384 to 322 BC), was the first to classify all animals in his Entomology Paleontology Ichthyology Histology Correct Answer : Histology Ques 2) _ is the branch of zoology concerned … General Awareness -Biology SSC CGL … Identify the animal-Adamsia(Sea anemone) b. General Instructions to candidates : There is a ‘cool off time’ of 10 minutes each for Botany and Zoology in addition to the writing time of 1 hour each.

Nautilus does not have suckers on its numerous prehensile arms. These analyses revealed that the various neurons of the honeybee olfactory pathway in vitro have different current phenotypes, which may reflect functional differences between the neuron types in vivo.

The class Scyphozoa, or true jellyfish, are characterized by a predominant medusa life-stage consisting of a bell and venomous tentacles used for hunting and defense, as well … ¾ Animals which do not possess a body cavity are called acoelomates. Respiratory system Tracheal system of dissected cockroach. Neurons have been identified in a wide range of invertebrate species, including annelids, molluscs, nematodes and arthropods. Ø Adamsia (Sea anemone) ... Neurons, the unit of neural system are excitable cells. Although we have gained invaluable information from this, in this study we argue that our approach to comparative learning research is rather deficient. -No d.
