Consider the following statements: 1. All Echinoderms are not marine 2. Sponges are exclusively marine 3. Insects are found in all kinds of habitats 4. Many primates are arboreal Which of the statements given above is/are correct? Correct Answer 3 and 4 only

The correct answer is option 2, i.e 3 and 4 only.

Echinoderms

  • The organisms belonging to the phylum Echinodermata or Echinoderms are exclusively marine. Hence statement 1 is incorrect.
  • Members of phylum Echinodermata (Spiny bodied) have an endoskeleton of calcium carbonate.
  • These are multicellular organisms with well-developed organ systems.
  • They have a star-like appearance and are spherical or elongated.
  • They possess the power of regeneration.
  • Starfish, sea cucumbers, sea urchins and brittle stars are examples of echinoderms.

Sponges

  • The Phylum Porifera mainly refers to the pore bearers or pore bearing species.
  • Poriferans are pore-bearing first multicellular animals, the pores are known as Ostia.
  • The poriferans have a spongy appearance and are therefore called sponges.
  • They are mostly found in marine water, only a few are found in freshwater. Hence statement 2 is incorrect.
  • Their body is usually cylindrical.

Insects

  • Insects are animals with segmented bodies, six jointed legs, and exoskeletons.
  • Some insects have wings, but not all. 
  • Insects live in every habitat on Earth, from the sands of hot deserts to cold snowy mountain streams. Hence statement 3 is correct.
  • Examples of insects include ants, butterflies, and beetles but not the scorpions, spiders, centipedes and millipedes

Primates

  • Primates belong to animal kingdom of class mammalian of phylum vertebrate.
  • Primate includes diversified group animals such as Lemurs, Lorises, Tarsiers, Monkeys, Apes and Humans.
  • Since all primates are descendent of tree-dwellers, they exhibit adaptive features which allow them to climb trees hence many of them are arboreal. Hence, statement 4 is correct.
  • Primate brains are large relative to their body size, compared to other mammals.
  • Almost all primates are diurnal.

In each of the following question below are given some statements followed by some conclusions. Taking the given statements to be true even if they seem to be at variance from commonly known facts, read all the conclusions and then decide which of the given conclusion logically follows the given statements. Statements: I. All insects are dangerous. II. All machines are dangerous. Conclusions: I. All dangerous are insects. II. All dangerous are machines. III. Some machines are insects.
"There are holes or 'pores', all over the body. They are commonly called 'sponges', and are mainly found in marine habitats."
The above statement signifies which of the following phylums?
The statements below are followed by two conclusions labeled I and II. Assuming that the information in the statements is true, even if it appears at variance with generally established facts, decide which conclusion(s) logically and definitely follow(s) from the information given in the statements. Statements: 1) Some men are insects. 2) Some larvae are insects. Conclusion I. Some insects are larvae. II. Some insects are men.
Bed bugs are parasitic insects in the genus Cimex that feed exclusively on blood. Cimex lectularius, the common bed bug, is the best known as it prefers to feed on human blood. The name bed bug derives from the preferred habitat of Cimex lectularius: warm houses and especially near or inside beds or other sleep areas. Bed bugs are mainly active at night, but are not exclusively nocturnal. They usually feed on their hosts without being noticed. A number of adverse health effects may results from bed bug bites, including skin rashes, psychological effects, and allergic symptoms. Bed bugs are not known to transmit any pathogens as disease vectors. Certain signs and symptoms suggest the presence of bed bugs; finding the adult insects confirms the diagnosis. Assuming the information in the given paragraph is true, choose the correct statement.
In the question three statements are given, followed by three conclusions, I, II and III. You have to consider the statements to be true even if it seems to be at variance from commonly known facts. You have to decide which of the given conclusions, if any, follows from the given statements. Statement I: All caterpillars are butterflies. Statement II: Some caterpillars are insects. Statement III: No butterflies are animals. Conclusion I: Some insects are butterflies. Conclusion II: All insects are animals. Conclusion III: Some animals are caterpillars.
Read the following passage carefully and choose the most appropriate answer to the question out of the four alternatives.
Riparian vegetation [the green band of vegetation along a watercourse] can help stabilize stream banks; filter sediment from surface runoff; and provide wildlife habitat, livestock forage,and scenic value. Well-developed vegetation also allows bank soils to absorb extra water during spring runoff, releasing it later during drier months, thus improving late-summer stream flows. In many parts of the arid West, trees and shrubs are found only in riparian areas. Woody plants are very important as winter cover for many wildlife species, including upland game birds such as pheasants and turkeys. Often this winter cover is the greatest single factor limiting game bird populations. Woody vegetation also provides hiding cover and browse for many other species of birds and mammals, both game and nongame. Dead trees ("snags") are an integral part of streamside habitats and should be left standing whenever possible. Woodpeckers, nuthatches, brown creepers, and other birds eat the insects that decompose the wood. These insects usually pose no threat to nearby living trees. Occasionally a disease organism or misuse of pesticides will weaken or kill a stand of trees. If several trees in a small area begin to die, contact your local extension agent immediately . How dependent are plants and animals on each other?
